ExxonMobil Guyana has agreed to conduct a suite of studies to ensure the operational efficiencies and integrity of its Stabroek Block projects are preserved for decades to come.
According to the Petroleum Production Licence for the Uaru Development Project, Exxon’s affiliate and Stabroek Block operator, Esso Exploration and Production Guyana Limited (EEPGL) is expected to conduct studies associated with the Subsea Umbilicals, Risers and Flowlines (SURF), drilling and FPSO Systems.
With respect to SURF, EEPGL will examine Stabroek’s wide area seabed congestion, operational failure of subsea manifolds, solids monitoring and mitigation/remediation strategy.
For drilling, it will conduct a Pore Pressure Maintenance Casing and Tubing Design Study as well as a Downhole Sand Control Design Study.
For FPSO, authorities have asked that EEPGL provide a Comprehensive Reliability, Availability and Maintainability (RAM) Study, a Topsides Metering Accuracy Report, and confirmation that the gas handling capacity is sufficient for simultaneous gas lift, export and injection.
Following the signing of the Uaru licence on April 17, 2023, EEPGL has 30 days from the date of signing to submit the terms of reference, methodology and workplan (including the schedule of activities) of the study for the approval of the subject minister.
Within 180 days of the date of the said approval or such later timeline as directed by the minister, EEPGL would be required to complete the study’s final report.
The licence also notes that 30 days before completion of the study, EEPGL will issue a draft final report to enable the minister to input into the final report. The consolidated reports would not be deemed final until approved by the minister, taking into account whether the report meets the terms of reference, methodology, all related best practice technical standards and completeness of outputs.
EEPGL currently leads five sanctioned projects in the oil rich Stabroek Block, all of which will propel Guyana to produce over one million barrels of oil by 2026.
