The scope project is aimed at:
improving our understating of the impacts of H2S and CO2 environment on oil and gas tubulars and cement; establishing how commonly used tubulars and cement are affected by exposure to H2S and/or CO2 in HPHT wells; determining the capability of these materials to function properly in harsh downhole environments; developing new cement formulations which are suitable for HPHT sour gas environment; evaluating corrosion resistance of common steel used in the field; selecting special steel materials that have better sour gas corrosion resistant under HPHT conditions; and providing recommendations and guidelines to ensure long term integrity of the well.
The project staff has established a Technical Advisory Board with industry experts. This group meets twice a year and has aided in establishing specimen preparation, testing protocol, and shared lessons learned from past research. The cement focused studies will occur in years one and two of this project. The testing facility has been built and the cement specimens are in the aging cell. The tubular focused studies will occur in years two and three of this project.
