HKN, Inc. is a company engaged in hydrocarbon exploration headquartered in Southlake, Texas . It is notable for the Harken Energy scandal , which involved allegations of insider trading by George W. Bush in 1990. The company was known as Harken Energy Corporation until 2007.
68-427: In 1973, the company was founded as an unprofitable collection of Texas oil wells for investors seeking tax write-offs . In 1986, the company acquired Spectrum 7 for 200,000 shares from George W. Bush. After the sale of his company, Bush served on the board of directors of the company and received $ 80,000-$ 100,000 per year in consulting fees. Bush remained on the board through 1993. In 1987, Talat Othman joined
136-412: A drilling rig , which contains all necessary equipment to circulate the drilling fluid, hoist and rotate the pipe, remove cuttings from the drilling fluid, and generate on-site power for these operations. After drilling and casing the well, it must be 'completed'. Completion is the process in which the well is prepared to produce oil or gas. In a cased-hole completion, small perforations are made in
204-480: A "sweep" effect to push hydrocarbons out of the reservoir. Such methods require the use of injection wells (often chosen from old production wells in a carefully determined pattern), and are used when facing problems with reservoir pressure depletion or high oil viscosity, sometimes being employed early in a field's life. In certain cases – depending on the reservoir's geomechanics – reservoir engineers may determine that ultimate recoverable oil may be increased by applying
272-400: A 20-year concession to exploit resources offshore Costa Rica . After pressure from indigenous tribes and environmentalists, operating as Acción de Lucha Anti-Petrola , the government instituted a moratorium on exploration. In September 2003, the company filed a dispute seeking $ 57 billion from the government of Costa Rica for lost earnings. The lawsuit was thrown out of court and the concession
340-412: A V0-rated, gas-tight seal that cement cannot provide. Some abandoned wells are subsequently plugged and the site is remediated; however, the cost of such efforts can be in the millions of dollars. In this process, tubing is removed from the well, and sections of wellbore are filled with cement to isolate the flow path between gas and water zones from each other, as well as from the surface. The wellhead
408-401: A disposal problem at wells that are developed to produce oil. If there are no pipelines for natural gas near the wellhead it may be of no value to the oil well owner since it cannot reach the consumer markets. Such unwanted gas may then be burned off at the well site in a practice known as production flaring , but due to the energy resource waste and environmental damage concerns this practice
476-422: A high pressure, high-temperature well of duration 100 days can cost about US$ 30 million. Onshore wells can be considerably cheaper, particularly if the field is at a shallow depth, where costs range from less than $ 4.9 million to $ 8.3 million, and the average completion costing $ 2.9 million to $ 5.6 million per well. Completion makes up a larger portion of onshore well costs than offshore wells, which generally have
544-473: A large number of neglected or poorly maintained wellheads is a large environmental issue: they may leak methane or other toxic substances into local air, water and soil systems. This pollution often becomes worse when wells are abandoned or orphaned – i.e., where wells no longer economically viable are no longer maintained by their (former) owners. A 2020 estimate by Reuters suggested that there were at least 29 million abandoned wells internationally, creating
612-516: A marked avoidance of areas near oil wells and seismic lines due to disturbances. Drilling often destroys wildlife habitat, causing wildlife stress, and breaks up large areas into smaller isolated ones, changing the environment, and forcing animals to migrate elsewhere. It can also bring in new species that compete with or prey on existing animals. Even though the actual area taken up by oil and gas equipment might be small, negative effects can spread. Animals like mule deer and elk try to stay away from
680-424: A mud motor while drilling to achieve a depth of over 12,000 metres (12 km; 39,000 ft; 7.5 mi). Until the 1970s, most oil wells were essentially vertical, although lithological variations cause most wells to deviate at least slightly from true vertical (see deviation survey ). However, modern directional drilling technologies allow for highly deviated wells that can, given sufficient depth and with
748-450: A raw form known as associated petroleum gas , is almost always a by-product of producing oil. The short, light-gas carbon chains come out of solution when undergoing pressure reduction from the reservoir to the surface, similar to uncapping a bottle of soda where the carbon dioxide effervesces . If it escapes into the atmosphere intentionally it is known as vented gas , or if unintentionally as fugitive gas . Unwanted natural gas can be

Factors such as sagebrush cover and precipitation seemed to have little effect on count changes. These results align with other studies highlighting the detrimental impact of oil and gas development on sage-grouse populations. Orphan wells Orphan , orphaned, or abandoned wells are oil or gas wells that have been abandoned by fossil fuel extraction industries . These wells may have been deactivated because had become uneconomic, failure to transfer ownerships (especially at bankruptcy of companies ), or neglect, and thus no longer have legal owners responsible for their care. Decommissioning wells effectively can be expensive, costing several thousands of dollars for

Thus the burden may fall on government agencies or surface landowners when a business entity can no longer be held responsible. Orphan wells are a potent contributor of greenhouse gas emissions , such as methane emissions , contributing to climate change . Much of this leakage can be attributed to failure to have them plugged properly or leaking plugs. A 2020 estimate of abandoned wells in

Much of this leakage can be attributed to failure to have them plugged properly or leaking plugs. A 2020 estimate of abandoned wells in
1020-523: A shallower reservoir. Such remedial work can be performed using workover rigs – also known as pulling units , completion rigs or "service rigs" – to pull and replace tubing, or by the use of well intervention techniques utilizing coiled tubing . Depending on the type of lift system and wellhead a rod rig or flushby can be used to change a pump without pulling the tubing. Enhanced recovery methods such as water flooding, steam flooding, or CO 2 flooding may be used to increase reservoir pressure and provide
1088-543: A significant source of greenhouse gas emissions worsening climate change. The earliest known oil wells were drilled in China in 347 CE. These wells had depths of up to about 240 metres (790 ft) and were drilled using bits attached to bamboo poles. The oil was burned to evaporate brine producing salt . By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to
1156-645: A similar technique used by Enron that led to the Enron scandal . In September 1989, the company made an offer to acquire Tesoro Petroleum . The offer was withdrawn in February 1990. In 2007, the company changed its name to HKN, Inc. Harken attracted attention because of the role played in its affairs during the 1980s by George W. Bush, later the President of the United States . On June 22, 1990, while he

Orphan , orphaned, or abandoned wells are oil or gas wells that have been abandoned by fossil fuel extraction industries . These wells may have been deactivated because had become uneconomic, failure to transfer ownerships (especially at bankruptcy of companies ), or neglect, and thus no longer have legal owners responsible for their care. Decommissioning wells effectively can be expensive, costing several thousands of dollars for
1292-399: A well depends mainly on the daily rate of the drilling rig, the extra services required to drill the well, the duration of the well program (including downtime and weather time), and the remoteness of the location (logistic supply costs). The daily rates of offshore drilling rigs vary by their depth capability, and the market availability. Rig rates reported by industry web service show that
1360-410: Is becoming less common. Often, unwanted (or 'stranded' gas without a market) gas is returned back into the reservoir with an 'injection' well for storage or for re-pressurizing the producing formation. Another solution is to convert the natural gas to a liquid fuel. Gas to liquid (GTL) is a developing technology that converts stranded natural gas into synthetic gasoline, diesel or jet fuel through
1428-601: Is cut off, a cap is welded in place and then the stub is buried as the land contours are restored. The primary method of plugging wells is through elastomer and cement plugs. Government-led campaigns to plug wells are expensive but often facilitated by oil and gas taxes, bonds, or other fees applied to production. Environmental non-profit organizations, such as the Well Done Foundation , also carry out well-plugging projects and develop programs alongside government entities. Oil and gas companies on public land in

These orphaned wells can allow gas and oil to contaminate groundwater due to improper sealing. Orphan wells in Alberta, Canada are inactive oil or gas well sites that have no solvent owner that can be held legally or financially accountable for
1564-559: Is far more costly than a comparable onshore well. These wells dot the Southern and Central Great Plains, Southwestern United States, and are the most common wells in the Middle East. Another way to classify oil wells is by their purpose in contributing to the development of a resource. They can be characterized as: At a producing well site, active wells may be further categorized as: Lahee classification [1] The cost to drill
1632-688: Is not possible to determine. Once a well is abandoned, it can be a source of toxic emissions and pollution contaminating groundwater and releasing methane , making orphan wells a significant contributor to national greenhouse gas emissions . For this reason, several state and federal programs have been initiated to plug wells; however, many of these programs are under capacity. In states like Texas and New Mexico , these programs do not have enough funding or staff to fully evaluate and implement mitigation programs. North Dakota dedicated $ 66 million of its CARES Act pandemic relief funds for plugging and reclaiming abandoned and orphaned wells. According to
1700-495: Is often difficult mechanically and expensive. Traditionally elastomer and cement plugs have been used with varying degrees of success and reliability. Over time, they may deteriorate, particularly in corrosive environments, due to the materials from which they are manufactured. New tools have been developed that make re-entry easier; these tools offer higher expansion ratios than conventional bridge plugs and higher differential pressure ratings than inflatable packers, all while providing
1768-597: Is underfunded by at least several hundred million. The total estimate for cleaning up all existing sites is as much as $ 260 billion. Remediation is paid for through federal and provincial bailouts, a PPP violation. Though different jurisdictions have varying criteria for what exactly qualifies as an orphaned or abandoned oil well, generally speaking, an oil well is considered abandoned when it has been permanently taken out of production. Similarly, orphaned wells may have different legal definitions across different jurisdictions, but can be thought of as wells whose legal owner it

These valves regulate pressures, control flows, and allow access to the wellbore in case further completion work is needed. From the outlet valve of the production tree, the flow can be connected to a distribution network of pipelines and tanks to supply the product to refineries, natural gas compressor stations, or oil export terminals. As long as

Proponents claim GTL fuels burn cleaner than comparable petroleum fuels. Most major international oil companies are in advanced development stages of GTL production, e.g. the 140,000 bbl/d (22,000 m /d) Pearl GTL plant in Qatar, scheduled to come online in 2011. In locations such as
1972-601: The Government Accountability Office , the 2.1 million unplugged abandoned wells in the United States could cost as much as $ 300 billion. A joint Grist and The Texas Observer investigation in 2021 highlighted how government estimates of abandoned wells in Texas and New Mexico were likely underestimated and that market forces might have reduced prices so much creating peak oil conditions that would lead to more abandonment. Advocates of programs like
2040-576: The Green New Deal and broader climate change mitigation policy in the United States have advocated for funding plugging programs that would address stranded assets and provide a Just Transition for skilled oil and gas workers. The REGROW Act, which is part of the Infrastructure Investment and Jobs Act , includes $ 4.7 billion in funds for plugging and maintaining orphaned wells. The Interior Department has documented

These places were described by Marco Polo in the 13th century, who described the output of those oil wells as hundreds of shiploads. When Marco Polo in 1264 visited Baku, on the shores of the Caspian Sea , he saw oil being collected from seeps. He wrote that "on

2176-402: The United States must post financial assurance to cover the cost of plugging wells if they go bankrupt or cannot plug the well themselves. The current financial assurance requirement, which has been in place for 60 years, is $ 10,000 per well. This is significantly less than the cost of plugging a well, ranging as high as $ 400,000. Thus many federal oil and gas leases have a bond that cannot cover

Wells can be located: Offshore wells can further be subdivided into While the location of the well will be a large factor in the type of equipment used to drill it, there is actually little downhole difference in the well itself. An offshore well targets a reservoir that happens to be underneath an ocean. Due to logistics and specialized equipment needed, drilling an offshore well
2448-520: The added cost burden of a surface platform. The total costs mentioned do not include the those associated with the risk of explosion and leakage of oil. Those costs include the cost of protecting against such disasters, the cost of the cleanup effort, and the hard-to-calculate cost of damage to the company's image. The impacts of oil exploration and drilling are often irreversible, particularly for wildlife. Research indicates that caribou in Alaska show

In 1989, the company's subsidiary Aloha Petroleum was sold to company insiders for $ 12 million, most of which was borrowed from Harken. The sale of the subsidiary for an exorbitant price helped the company show a profit that year and disguise losses,
2584-400: The borehole. Screens also control the migration of formation sands into production tubulars, which can lead to washouts and other problems, particularly from unconsolidated sand formations. After a flow path is made, acids and fracturing fluids may be pumped into the well to fracture , clean, or otherwise prepare and stimulate the reservoir rock to allow optimal production of hydrocarbons into
2652-404: The case of horizontal wells. These new systems allow casing to run into the lateral zone equipped with proper packer/frac-port placement for optimal hydrocarbon recovery. The production stage is the most important stage of a well's life: when the oil and gas are produced. By this time, the oil rigs and workover rigs used to drill and complete the well will have moved off the wellbore, and the top
2720-775: The casing from corrosive well fluids. In many wells, the natural pressure of the subsurface reservoir is high enough for the oil or gas to flow to the surface. However, this is not always the case, especially in depleted fields where the pressures have been lowered by other producing wells, or in low-permeability oil reservoirs. Installing a smaller diameter tubing may be enough to help the production, but artificial lift methods may also be needed. Common solutions include surface pump jacks , downhole hydraulic pumps or gas lift assistance. Many new systems in recent years have been introduced for well completion. Multiple packer systems with frac ports or port collars in an all-in-one system have cut completion costs and improved production, especially in

2856-431: The cost of cleanup. New rules related to the Infrastructure Investment and Jobs Act will increase the financial assurance requirement to a minimum of $ 150,000 per well. This will help ensure that oil and gas companies have the financial resources to plug wells if they can no longer do so themselves. Unused wells, especially from natural gas might be used for carbon capture or storage. However, if not sealed properly, or

With deepwater drilling rig rates in 2015 of around $ 520,000/day, and similar additional spread costs, a deepwater well of a duration of 100 days can cost around US$ 100 million. With high-performance jackup rig rates in 2015 of around $ 177,000, and similar service costs,

The target (the endpoint of the well) will be matched with a surface location (the starting point of the well), and a trajectory between the two will be designed. There are many considerations to take into account when designing
3128-464: The economic limit is increased, the useful life of the well is shortened and proven oil reserves are lost. Conversely, when the financial limit is lowered, the life of the well is lengthened. When the economic limit is reached, the well becomes a liability if not abandoned . At the economic limit, a significant amount of unrecoverable oil is often left in the reservoir. It might be tempting to defer physical abandonment for an extended period, hoping that

Ignacy Łukasiewicz , a Polish pharmacist and petroleum industry pioneer drilled one of the world's first modern oil wells in 1854 in Polish village Bóbrka, Krosno County who in 1856 built one of the world's first oil refineries . In North America, the first commercial oil well entered operation in Oil Springs, Ontario in 1858, while the first offshore oil well

The Sage-grouse is another example of an animal that tries to avoid areas with drilling, which can lead to fewer of them surviving and reproducing. Different studies show that drilling in their habitats negatively impacts sage-grouse populations. In Wyoming , sage grouse studied between 1984 and 2008 show
3332-650: The oil price will increase or that new supplemental recovery techniques will be perfected. In these cases, wells are merely shut in, or temporary plugs may be placed downhole. There are thousands of "temporarily abandoned" wells throughout North America, waiting to see what the market will do before permanent abandonment. However, lease provisions and governmental regulations often require quick abandonment; liability and tax concerns also may favor abandonment. Theoretically, an abandoned well can be re-entered to restore production (or converted to injection service for supplemental recovery or downhole hydrocarbon storage), but reentry
3400-403: The portion of the casing across the production zone, to provide a path for the oil to flow from the surrounding rock into the production tubing. In open hole completion, often a 'sand screen' or 'gravel pack' is installed in the last-drilled but uncased reservoir section. These maintain structural integrity of the wellbore in the absence of casing, while still allowing flow from the reservoir into
3468-409: The potential to contaminate land, air and water, potentially harming ecosystems, wildlife, livestock, and humans. For example, many wells in the United States are situated on farmland, and if not maintained could contaminate soil and groundwater with toxic contaminants. A well is said to reach an "economic limit" when revenue from production does not cover the operating expenses, including taxes. If

#17327880219263536-439: The pressure in the reservoir remains high enough, the production tree is all that is required to produce the well. If the pressure depletes and it is considered economically viable, an artificial lift method mentioned in the completions section can be employed. Workovers are often necessary in older wells, which may need smaller diameter tubing, scale or paraffin removal, acid matrix jobs, or completion in new zones of interest in
3604-435: The price of oil and gas, a well may be unproductive, but if prices rise, even low-production wells may be economically valuable. Moreover, new methods, such as hydraulic fracturing (a process of injecting gas or liquid to force more oil or natural gas production) have made some wells viable. However, peak oil and climate policy surrounding fossil fuels have made fewer of these wells and costly techniques viable. However,

Cement slurry will be pumped down the inside to rise in the annulus between the borehole and the outside of the casing. The casing provides structural integrity to that portion of the newly drilled wellbore, in addition to isolating potentially dangerous high pressure zones from lower-pressure ones, and from
3740-448: The proper tools, actually become horizontal. This is of great value as the reservoir rocks that contain hydrocarbons are usually horizontal or nearly horizontal; a horizontal wellbore placed in a production zone has more surface area in the production zone than a vertical well, resulting in a higher production rate. The use of deviated and horizontal drilling has also made it possible to reach reservoirs several kilometers or miles away from

An operator's liability for surface reclamation issues continues for 25 years following the issuance of a site reclamation certificate. There is also a lifelong liability in case of contamination. Once the current environmental legislation
3876-562: The storage site is not sufficiently sealed, there is a possibility of leakage. A 2014 study in China evaluated the use of abandoned wells for geothermal power generation. A similar study followed in 2019 for natural gas wells. Hydraulic fracturing, also known as fracture treating or fracking, is the process of fracturing bedrock with pressurized liquids. This creates cracks in rock formations that allow natural gas , petroleum , and brine to flow more effortlessly. When hydraulic fracturing

With these zones safely isolated and the formation protected by the casing, the well can be drilled deeper (into potentially higher-pressure or more-unstable formations) with a smaller bit, and then cased with a smaller size pipe. Modern wells generally have two to as many as five sets of subsequently smaller hole sizes, each cemented with casing. This process is all facilitated by

These assumptions are used by a well engineering team designing the casing and completion programs for the well. Also considered in the detailed planning are selection of the drill bits, Bottom hole assembly , and the drilling fluid Step-by-step procedures are written to provide guidelines for executing
4080-406: The trajectory such as the clearance from any nearby wells (anti-collision) or future wellpaths. Before a well is drilled, a geologic target is identified by a geologist or geophysicist to meet the objectives of the well. When the well path is identified, a team of geoscientists and engineers will develop a set of presumed characteristics of the subsurface path that will be drilled through to reach

With the interplay with many of the elements in a well's design, trajectories and designs often go through several iterations before the plan is finalized. The well is created by drilling a hole 12 cm to 1 meter (5 in to 40 in) in diameter into the earth with a drilling rig that rotates a drill string with a bit attached. At depths during
4284-481: The wellbore. Usually the area above the producing section of the well is packed off inside the casing, and connected to the surface via a smaller diameter pipe called tubing. This arrangement provides a redundant barrier to leaks of hydrocarbons as well as allowing damaged sections to be replaced. Also, the smaller cross-sectional area of the tubing gives reservoir fluids an increased velocity to minimize liquid fallback that would create additional back pressure, and shields

The process of modern drilling for wells first started in the 19th century but was made more efficient with advances to oil drilling rigs and technology during the 20th century. Wells are frequently sold or exchanged between different oil and gas companies as an asset – in large part because during falls in

The earliest oil wells in modern times were drilled percussively, by repeatedly raising and dropping a bit on the bottom of a cable into the borehole. In the 20th century, cable tools were largely replaced with rotary drilling , which could drill boreholes to much greater depths and in less time. The record-depth Kola Borehole used

OWA's Inventory does not include legacy wells which are more complex, time-intensive and costly to remediate. Following the 2014 downturn in the global price of oil, there was a "tsunami" of orphaned wells, facilities, and pipelines resulting from bankruptcies. As of March 2023, oil and gas companies owe rural municipalities $ 268 million in unpaid taxes; they owe landowners "tens of millions in unpaid lease payments". Original owners of what are now orphan wells "failed to fulfill their responsibility for costly end-of-life decommissioning and restoration work"; some sold these wells "strategically to insolvent operators". Landowners suffer both "environmental and economic consequences" of having these wells on their property. OWA funding
