Major Hydrocarbon Field Discovered in Kazakhstan

A major hydrocarbon field has been discovered in Kazakhstan’s Atyrau Region, with reserves potentially comparable to those of the Kashagan oil field, the country’s largest oil source, according to Kurmangazy Iskaziyev, First Deputy Chairman of the Management Board of KazMunayGas. The site is located on the Zhylyoi Platform near the Caspian Sea coast. Its onshore location could significantly reduce development costs, although the deposits are believed to lie at considerable depths. Kashagan has long stood as the symbol of both Kazakhstan’s oil wealth and the technical difficulty of extracting it. The offshore field cemented the country’s position as a major crude producer, but also became known for cost overruns, delays, and the engineering challenges of operating in the northern Caspian. Any onshore discovery mentioned in the same breath immediately raises expectations that it could avoid some of those constraints while delivering comparable scale. Kashagan, discovered in the northern Caspian Sea, remains one of the largest oil fields found globally in recent decades. Its recoverable reserves are estimated at 9–13 billion barrels of oil, with gas reserves exceeding 1 trillion cubic meters. Development is carried out by the North Caspian Operating Company consortium, which includes Shell, TotalEnergies, ExxonMobil, Eni, China National Petroleum Corporation, Inpex, and KazMunayGas. Speaking at the Geoscience & Exploration Central Asia forum, Iskaziyev said the resource potential of the Zhylyoi Block, including Karaton, Kazhygali, and Zhylyoi, is estimated at 4.7 billion tons, with total geological potential reaching up to 20 billion tons of oil equivalent. At this stage, such figures reflect geological potential rather than proven, recoverable reserves. In Kazakhstan, as elsewhere, moving from estimate to production depends on depth, pressure, sulfur content, and the cost of drilling and processing. Large discoveries can take years to confirm commercially, particularly in high-pressure or technically complex formations. KazMunayGas has already begun exploration work. A well 5,750 meters deep has been drilled at the Karaton site, and five promising targets have been identified as part of a joint project with Tatneft. During testing at one of these sites, a gas flow containing hydrogen sulfide was recorded. The main challenge remains the depth of the deposits, which may reach up to 9 km. According to Iskaziyev, these conditions are comparable to projects undertaken by KazMunayGas’s Chinese partners, including Sinopec and China National Petroleum Corporation, where drilling depths can reach up to 11 km. The company plans to expand geological exploration into neighboring areas, including Kazhygali, and is negotiating subsoil use contracts. The timing is significant. Kazakhstan is under growing pressure to demonstrate that its oil sector can still deliver major new projects as existing fields mature. A large onshore discovery in Atyrau would reinforce the region’s role as the core of the country’s energy system and support efforts to sustain export volumes and investor interest. At the forum, a memorandum of understanding was also signed between KazMunayGas and BP on cooperation in geological exploration and the development of the Ustyurt Block in the Mangistau Region.

Kazakhstan Expands Kashagan Legal Fight as Arbitration and Claims Mount

For several years, Kazakhstan has been engaged in arbitration proceedings worth billions of dollars, many of which have been conducted behind closed doors. Recently, new details have emerged about one of the largest disputes, involving the North Caspian Operating Company (NCOC). The dispute stems from environmental violations identified during a 2022 inspection at the Kashagan field. Environmental authorities found that the operator, NCOC, had stored approximately 1.2 million tons of sulfur in excess of permitted limits. As a result, the company faced a fine of around $5 billion. Kashagan is one of the largest and most technically complex offshore oil fields ever discovered, with proven hydrocarbon reserves estimated at 4.65 billion tons. The consortium includes seven major international energy companies: KazMunayGas (16.88%); Eni (16.81%); Shell (16.81%); ExxonMobil (16.81%); TotalEnergies (16.81%); CNPC (8.33%); and INPEX Ltd (7.56%). A lawsuit was filed by all consortium members except KazMunayGas, Kazakhstan’s national oil company. The field has long been central to Kazakhstan’s oil production and relations with international investors. Kazakhstan’s interests in the Kashagan dispute are represented by the Ministry of Ecology and the Ministry of Justice. According to the Vice Minister of Justice, Daniel Vaisov, a trial court has already ruled in favor of the state. “A first-instance court has ruled in Kazakhstan, recognizing the state’s position as lawful. Six contractors — excluding KazMunayGas — filed an appeal in March,” Vaisov said. NCOC challenged the environmental inspection results. In June 2023, a court in Astana partially upheld the company’s claims. However, this was overturned in February 2024, when an appellate court ruled in favor of the government, confirming the inspection’s legality. Subsequent developments have further complicated the case. In August 2025, an Astana court overturned the environmental agency’s order, citing procedural violations. The case is once again under appeal. At the same time, the contractors have challenged the $5 billion fine through international arbitration. The proceedings are set to take place in Washington at the International Centre for Settlement of Investment Disputes (ICSID), where the arbitral tribunal is currently being formed, Vaisov said. The case is being closely watched as a test of how far Kazakhstan is willing to push legal pressure on major Western energy investors. Separately, Kazakhstan is pursuing much larger claims against Kashagan consortium members under the production-sharing agreement. In May 2024, Kazakhstan’s Ministry of Energy said claims against Kashagan project developers could reach up to $150 billion. Initially, the government sought $15 billion from NCOC. It later increased its claims by a further $138 billion, citing lost profits linked to oil volumes that investors had committed to supply to the state. The Ministry of Energy has described the dispute as purely commercial, relating to Kazakhstan’s rights under the production-sharing agreement. Officials maintain that the legal proceedings do not affect the investment standing of project participants. Separately, in January last year, an economic court in Astana ordered NCOC to pay 3.5 billion KZT (about $8 million) for excessive flaring of raw gas. In addition to Kashagan, Shell is involved in...

Kazakhstan–Kashagan Dispute Heads to International Arbitration

Kazakhstan’s Vice Minister of Justice, Daniel Vaisov, announced that the country’s claims over the removal of sulfur storage limits at the Kashagan field, operated by North Caspian Operating Company N.V. (NCOC), will be heard under the International Centre for Settlement of Investment Disputes framework, which is headquartered in Washington. NCOC includes Shell, TotalEnergies, Eni, ExxonMobil, CNPC, Inpex, and KazMunayGas. In March 2023, an inspection of the Kashagan consortium by Kazakhstan’s environmental authorities identified violations of environmental legislation, including the excessive storage of sulfur volumes exceeding permitted limits. The resulting claim was valued at around $5 billion, according to the authorities. A court of first instance in Kazakhstan ruled in favor of the environmental authorities, according to Vaisov. Six of the seven NCOC participants, excluding KazMunayGas, challenged the ruling in a Kazakh court in March this year. At the same time, the foreign investors initiated international arbitration proceedings. “This claim was filed under bilateral international agreements: the agreement between the Republic of Kazakhstan and the Republic of France, and the agreement between the Republic of Kazakhstan and the Kingdom of the Netherlands,” Vaisov said during a briefing. The Ministry of Justice, Ministry of Ecology, and Ministry of Energy are jointly handling the case. Kazakhstan has been steadily tightening its position in major energy projects, seeking a larger share of revenues from fields developed under production-sharing agreements signed in the 1990s. Disputes over Kashagan and Karachaganak reflect broader efforts to rebalance terms with foreign investors as production stabilizes and fiscal pressures grow. The outcome of these cases could reshape how Central Asia’s largest economy manages foreign participation in its energy sector. A separate dispute concerning project costs, reportedly exceeding $100 billion, is being handled under the framework of the Production Sharing Agreement (PSA), in line with government policy, Vaisov said. Kazakhstan maintains that under the current terms, participating oil companies receive up to 98% of revenue from oil production at Kashagan, leaving the state with comparatively limited income in the form of royalties. Astana’s claim related to this issue has been reported at approximately $160 billion. “As far as I know, an interim decision has been made regarding Karachaganak. Further work is currently underway,” Vaisov said. In January 2026, an international arbitration tribunal ruled in favor of Kazakhstan in its dispute with shareholders in the Karachaganak Oil and Gas Projects, Eni, Shell, Chevron, and Lukoil. Compensation for the shareholders’ unjustified reimbursement of expenses has yet to be determined, but experts estimate it at between $2 billion and $4 billion. Vaisov also noted that Kazakhstan has been reducing the cost of arbitration proceedings involving foreign investors. “The Ministry of Justice has managed to reduce spending on these matters each year. Since 2021, costs have been reduced by nearly threefold. At the same time, the Republic of Kazakhstan engages leading law firms for these proceedings, as contracting companies do the same,” he said.

Shell Signs New Exploration Deal in Kazakhstan Amid Legal Disputes

British energy company Shell has launched a new exploration project in Kazakhstan despite previously announcing that it would pause new investments in the country. On March 5, it was announced that Shell had signed a contract for geological exploration in the Aktobe region. The company has been involved in several legal disputes with Kazakhstan over subsoil use and had stated that it did not plan to invest further in the country’s energy sector. Geological Exploration Contract The Zhanaturmys site, which has attracted Shell’s interest, covers an area of 1,377 square kilometers and is located in one of Kazakhstan’s most actively developed oil and gas basins. The document was signed by Kazakhstan’s Deputy Energy Minister, Yerlan Akbarov, and Shell’s Senior Vice President and Chair in Kazakhstan, Suzanne Coogan. The contract provides for seismic exploration, data collection, and technical assessments. “The signing of today’s contract for geological exploration is further confirmation of Shell’s commitment to long-term cooperation with the Republic of Kazakhstan. Drawing on our global experience and advanced technologies, we intend to continue contributing to geological exploration and the expansion of the country’s resource base,” Coogan said. The agreement will remain in force until 2032. The project will be implemented under the terms of an improved model contract. According to Kazakhstan’s Energy Ministry, the company will allocate at least 100 million tenge (about $200,000) to finance socio-economic development in the region where the site is located. Shell is currently involved in three projects in Kazakhstan: the North Caspian Production Sharing Agreement (NCOC, 16.81% stake); the Karachaganak Production Sharing Agreement (29.25% stake); and the Caspian Pipeline Consortium (7.4% stake). Kazakhstan produces around 1.8–1.9 million barrels per day and hosts some of the world’s largest offshore reserves in the Caspian Sea. Western energy majors, including Shell, Chevron, ExxonMobil, and Eni, have operated in the country for decades through complex production-sharing agreements. Legal Disputes In February, Shell CEO Wael Sawan said the company would suspend new investments in Kazakhstan while legal proceedings with the government were ongoing. Numerous lawsuits filed by Kazakhstan, with claims amounting to billions of dollars, have reduced the company’s willingness to invest in the country, he said. “This affects our desire to continue investing in Kazakhstan. Although we see many opportunities for investment in the future, we will wait until we have a clearer picture of how things will turn out,” Sawan stated. Karachaganak and Kashagan Kazakhstan is currently involved in several legal disputes with Western oil companies, both in national courts and international arbitration. The cases concern two major oil and gas projects. One of them is Karachaganak. In 2023, the Kazakh government filed a lawsuit against the field's developers over cost deductions. The initial claim amounted to $3.5 billion but later increased to $6 billion after additional claims were filed. The project is operated by a consortium led by Eni and Shell, each holding a 29.25% stake. Other partners include Chevron (18%), Lukoil (13.5%, which has agreed to sell its stake), and KazMunayGas (10%). In January, it was...

Kashagan and Karachaganak: Will Kazakhstan’s Claims Lead to Changes in the Shareholder Structure?

The beginning of 2026 has been marked by a new round of confrontation between Kazakhstan and the international consortia developing the country’s largest oil and gas fields, North Caspian Operating Company N.V. (Kashagan) and Karachaganak Petroleum Operating B.V. (Karachaganak). Below is an overview of the current situation and the possible scenarios. Arbitration proceedings initiated in early 2023 have expanded from $16.5 billion to more than $170 billion. Over three years, Kazakhstan has secured preliminary victories on several claims, enough, in my view, to suggest that the era of foreign oil consortia dominating Kazakhstan’s strategic projects may be coming to an end. Ecology and NCOC Violations This week, Bloomberg reported in its article “Oil Majors Seek Arbitration Over $5 Billion Kazakh Sulfur Fine” that the NCOC consortium is filing in international arbitration to challenge a Kazakh court decision to collect 2.3 trillion tenge (KZT). The Bloomberg headline, however, presents the issue inaccurately. Environmental violations, including the excessive storage of approximately 1 million tons of sulfur, were identified during an inspection in March 2023, when the exchange rate stood at 451.71 KZT per $1. The rate later rose to 520-540 and currently stands at around 500 KZT per $1. According to investment forecasts, it may reach 600 KZT per $1 by the end of 2026. As a result, the dollar equivalent of the fine has decreased significantly. At the March 2023 rate, 2.3 trillion KZT amounted to approximately $5.1 billion. At 500 KZT per $1, it equals about $4.6 billion. At 600 KZT per $1, it would fall to roughly $3.8 billion, a difference of about $1.3 billion. After my earlier publications arguing that foreign consortia should be fined in foreign-currency equivalent at the exchange rate prevailing at the time of filing, the proposal was also raised in Parliament. Such an approach would be logical: the consortia export their oil and receive revenue in foreign currency, yet fines are imposed in tenge. After several rounds of appeals, the consortium lost what became the largest environmental dispute in Kazakhstan’s history, initially involving more than 20 systematic violations of environmental legislation. Correspondence between consortium members published in Western media indicated they were aware of the violations but considered remediation and compliance financially costly. NCOC’s annual revenue is approximately $10 billion. Media reports also stated that the consortium offered around $110 million, roughly 50 times less than the fine, for regional social programs in exchange for waiving environmental claims. Neither NCOC nor the Kazakh government confirmed such negotiations. In 2010-2011, similar environmental and tax claims against the Karachaganak consortium resulted in Kazakhstan receiving a 10% stake in the project. The current ownership structure of NCOC is: ENI (Italy) - 16.81% ExxonMobil (U.S.) - 16.81% CNPC (China) - 8.33% INPEX (Japan) - 7.56% TotalEnergies (France) - 16.81% Shell (UK) - 16.81% KazMunayGas (Kazakhstan) - 16.88% Total investment in Phase One of Kashagan is estimated at $60 billion. By analogy with Karachaganak, the environmental fine could hypothetically lead to an increase in Kazakhstan’s share by 5-7 percentage...

Kazakhstan vs Eni: How a Swiss Lawsuit Could Reshape the $160 Billion Kashagan Dispute

The legal landscape surrounding Kazakhstan’s energy sector has taken an unexpected turn. What began as a closed commercial arbitration dispute has now entered the public sphere in Switzerland’s courts. This marks a significant escalation in Astana’s confrontation with international oil and gas majors. According to Bloomberg, PSA LLP, a structure representing Kazakhstan’s interests in production-sharing agreements (PSAs), has significantly broadened its claims. The lawsuit now directly targets alleged schemes involving units and executives of the Italian company Eni. Kazakhstan alleges that during the early development of Kashagan infrastructure, including the Bolashak processing plant and pipeline systems, corruption and fraud may have occurred. Arbitration claims against the NCOC consortium, which includes Shell, ExxonMobil, TotalEnergies, and Eni, exceed $150 billion. Within this context, the Swiss case has become the most sensitive element. The Swiss case itself is much smaller – $15 million plus interest – and is being used to gather evidence and strengthen the larger arbitration case. While the financial stakes are high, the proceedings reflect a deeper political shift. Kazakhstan is moving away from the 1990s model of offering investors exceptional privileges. Under President Kassym-Jomart Tokayev’s “Fair Kazakhstan” policy, the state is aiming to secure more balanced and equitable cooperation with foreign partners. Distinctiveness of Swiss Proceedings The Swiss case is distinctive due to the nature of its allegations. The plaintiffs claim that during the tenure of Agip KCO (an Eni subsidiary) as project operator, contracts were awarded amid corrupt practices. Allegations include inflated prices and kickbacks to contractors. Targeting Eni is deliberate. The company led the project during its most troubled phase from 2001 to 2008. Kashagan’s budget swelled during this period, with repeated delays. Following a 2013 gas leak, production was halted for nearly three years. Kazakh officials have long linked Kashagan’s massive cost overruns and technical failures to poor procurement and mismanagement, and the current legal offensive zeroes in on alleged corrupt tenders. Cost estimates rose from a few tens of billions of dollars to around $60 billion, and by 2007, projections for total project costs had reached about $136 billion. Why Switzerland? The selection of the Swiss jurisdiction is strategic. Switzerland’s laws on corruption and financial crimes allow for the prosecution of both corporations and individual executives. Moreover, many entities connected to Kashagan’s operations are registered there. Another factor is the PSA’s stabilization clause, which forbids altering the contract’s terms. However, under international legal norms, if corruption is proven in the contract’s formation, such protections can be voided. This opens the door for Kazakhstan to challenge key financial terms of the agreement. Resource Nationalism 2.0: Legal Strategy Meets Political Logic Astana’s current posture can be described as a form of “new-generation resource nationalism.” Rather than using administrative leverage, the state is deploying legal tools to address grievances. This is driven in part by Kazakhstan’s fiscal needs, ranging from infrastructure upgrades to social spending. Amid these pressures, the vast expenditures reported by Kashagan operators have drawn public skepticism. Kazakhstan’s claims aim to re-evaluate the cost recovery model...
