Subsurface Integrity Review In Adnoc
Abu Dhabi, UAE
Oil & Gas Corrosion worked with Adnoc to assure fitness for purpose of the Asab and Bab subsurface facilities.
Adnoc needed to review the integrity of their subsurface facilities in Asab and Bab in order to assure the performance of the operation and, where required, to extend the operating life of their wells. To do this a pragmatic solution was required.
How our expertise helped Adnoc
Oil & Gas Corrosion, in collaboration with Xodus Group, carried out a subsurface integrity study by prioritising the focus on 9 areas:
1. Sustained annulus pressure (SAP)
2. Downhole inhibition
3. OGD (III) Project
5. External corrosion of casing
6. Tubing and casing inspection
7. Materials selection
8. Downhole deposition and wellhead
9. Switch over of oil to gas producers.
Details of Case Study
Oil & Gas Corrosion delivered project management and materials and corrosion expertise supported by the subsurface expertise from Xodus Group. The study delivered a series of recommendations that were ranked to select those that were easiest to implement and with the highest positive impact on the project. As a result of this study, Adnoc has been able to develop a robust business continuity plan for their subsurface operations as well as extend the life of their assets.
