Overview
Unaoil is a Monaco-based company that described its business as providing industrial solutions to the energy sector across the Middle East, Central Asia and Africa. The company was founded in 1991 and has been run by members of the Ahsani family. Public descriptions of its activities characterize it as an intermediary and services provider supporting oil and gas projects, including procurement, logistics and the facilitation of commercial relationships between international contractors and state-linked energy organizations. The company was incorporated in the British Virgin Islands, a jurisdiction frequently identified in reporting as having limited corporate transparency. Unaoil became internationally prominent not because of a consumer-facing product portfolio, but because of allegations that it acted as a facilitator for bribery in the oil and gas industry. The allegations covered projects and commercial relationships in countries including Iraq, Libya, Iran, Syria, Yemen, Kuwait and the United Arab Emirates. A central episode concerned a proposed Iraqi oil pipeline contract valued at approximately $500 million, for which Unaoil entered into an arrangement with Leighton Holdings in 2010. Leighton referred the matter to police in 2011 after corruption concerns arose. The allegations were later disputed by Unaoil, and litigation and investigative proceedings produced competing claims about the evidence and the conduct of the parties. In 2016, investigations by the United Kingdom Serious Fraud Office and the United States Department of Justice followed investigative reporting based on leaked Unaoil emails. The reporting alleged that the company helped Western engineering and energy companies obtain government-funded contracts by influencing tender processes, supplying inside information or arranging payments to officials. Unaoil denied the allegations and later argued that it had been targeted by an extortionist who obtained the emails through hacking. Monaco authorities searched Unaoil offices and residences connected with executives on 31 March 2016 at the request of British investigators. The investigations implicated or examined relationships involving companies such as Rolls-Royce, Halliburton-KBR, Petrofac, ABB, Leighton Holdings, Amec Foster Wheeler, KBR, FMC Technologies and Core Laboratories. In 2017, Rolls-Royce agreed with United States authorities to pay $170 million to resolve corruption allegations involving the use of intermediaries, including Unaoil. Petrofac suspended a senior executive while it faced scrutiny connected with the investigation. The case also generated criminal proceedings against former Unaoil personnel and senior Ahsani family members. Cyrus Ahsani and Saman Ahsani pleaded guilty in the United States in 2019 to roles in a scheme involving bribe payments to officials in multiple countries. In the United Kingdom, former Iraq territory managers Ziad Akle and Stephen Whiteley were convicted in proceedings concerning alleged payments connected with SBM Offshore contracts. Akle's conviction was quashed in 2021 after the Court of Appeal found serious disclosure failures by the Serious Fraud Office; a second conviction was overturned in 2022 on related grounds. A later independent review criticized senior SFO management and its handling of contacts with an intermediary. Because the available public material is dominated by investigations and litigation rather than current operating disclosures, Unaoil's present commercial status is unclear.
History
Unaoil was established in 1991 and became associated with the Ahsani family. Its reported business model centered on supplying industrial and commercial support to international energy companies operating in difficult or highly regulated markets. Rather than being known for producing fuel or owning a large consumer brand, Unaoil operated as a specialist intermediary, helping connect contractors with energy-sector opportunities and providing procurement, logistics and related project services. The company was based in Monaco but incorporated in the British Virgin Islands. The company's public profile changed after its involvement in an Iraqi pipeline opportunity. In 2010, Unaoil entered an agreement with Leighton Holdings concerning efforts to secure an Iraqi oil pipeline contract reportedly worth $500 million. Leighton referred the arrangement to police in 2011 because of suspected corruption. Unaoil rejected the allegations. The dispute continued through civil litigation, and a 2014 High Court proceeding questioned aspects of the corruption claims. In a later case, the Serious Fraud Office alleged that Unaoil had been involved in extensive corrupt conduct; Unaoil's challenge to the lawfulness of the SFO's actions was dismissed. In March 2016, the SFO formally began investigating alleged corrupt facilitation involving several major engineering, energy and oilfield-services companies. The United States Department of Justice also contacted companies in connection with its investigation. The inquiries followed reporting by Australian journalists based on a cache of internal emails dated from 2001 to 2012. The allegations described a system in which intermediaries allegedly used relationships with officials, tender manipulation, confidential information and payments to help international companies win government-funded projects in oil-producing countries. Unaoil and its legal representatives denied the allegations and said the company had been the victim of extortion and hacking. On 31 March 2016, Monaco authorities searched Unaoil premises and homes associated with executives. British officials participated, while the UK National Crime Agency coordinated with Australian and American law-enforcement bodies. The investigation widened to cover conduct in Iraq and other countries where Unaoil had operated, including Libya, Iran, Syria, Yemen, Kuwait and the United Arab Emirates. A former Unaoil country manager later told the BBC's Panorama programme that he had delivered cash to a Libyan government-linked official, adding to the public controversy. The investigation had consequences for several corporate counterparties. Rolls-Royce reached a 2017 settlement with United States authorities and agreed to pay $170 million over corruption allegations involving facilitators, including Unaoil. Petrofac suspended a senior executive amid scrutiny linked to the inquiry. In the United Kingdom, the SFO charged former Unaoil Iraq managers over alleged bribes connected with SBM Offshore contracts. Stephen Whiteley was sentenced to three years in prison in 2020, while Ziad Akle received a five-year sentence. Akle's conviction was quashed in 2021 after the Court of Appeal found that the SFO had failed to disclose material evidence. A related conviction was overturned in 2022 on similar grounds. In the United States, Cyrus Ahsani and Saman Ahsani pleaded guilty in 2019 to participating in a multinational bribery scheme. The UK case subsequently became an institutional controversy. An independent review published in July 2022 criticized the SFO's handling of the investigation, including senior leadership decisions and contacts with an intermediary who had no recognized legal role in the case. The public record does not establish a clear current operating structure or ongoing commercial scale for Unaoil, so its present status remains unknown.
