…over missing vendor records from General Ledger
The Guyana Government has already said it is going to arbitration with oil giant ExxonMobil, over the US$214.4 million that was flagged as questionable costs by auditors of expenses racked up between 1999 and 2017. One of the expenses that caused auditors to raise their eyebrows was US$40 million worth of well materials that were missing important vendor documentation.
A perusal of the recently-released final report of the 1999-2017 cost oil audit of ExxonMobil done by British firm IHS Markit shows that auditors had recommended the exclusion of the US$40 million sum from the cost bank. The auditors explained that while Exxon subsidiary Esso Exploration and Production Guyana Limited (EEPGL) recorded that this sum was spent, it did not record vendor details.
“During the audit period, EEPGL recorded expenditure of approximately $40.4 million on materials where the vendor details are not recorded in the General Ledger, this means that individual material entries in the General Ledger cannot be traced back to specific material purchase contracts.

“These costs relate to material issued from the shore base for use in petroleum operations. Although general material purchase contracts for similar materials were provided and reviewed, no evidence was provided to justify the costs of these materials. This amount should be removed from the cost bank,” IHS Markit said.
Meanwhile, it was explained by the audit firm that during the period under review, a total of US$143.3 million was spent on well materials that were predominantly casing, tubing and other downhole materials that were used to construct the wells. Troublingly, however, IHS noted that representatives of the Government of Guyana were not invited to witness material counts during these audits, even though this was a requirement in the Production Sharing Agreement (PSA).
“EEPGL record materials transactions when materials were taken from the shore base. Any unused materials are credited back to the General Ledger when materials are returned to the shore base. Within the General Ledger, it is not possible to positively link materials return transactions to the materials supplied transactions,” IHS Markit also revealed.
In 2019, IHS Markit had conducted the audit of ExxonMobil’s cost oil expenses incurred between 1999 and 2017 from its operations in Guyana and flagged US$214.4 million as questionable costs.
Following months of review, the Guyana Revenue Authority (GRA) – the technical body tasked with advising the Government on the audited oil expenses – supported the dispute of the US$214.4 million.
Based on the 2016 oil contract that was signed between ExxonMobil and the then A Partnership for National Unity/Alliance For Change (APNU/AFC) Government, Guyana will have to incur the cost of the oil company’s legal fees should the matter go to arbitration.
