Abstract
Regarding the widespread utilization of formate-based drilling fluids in numerous operational circumstances, petroleum industries are in urgent need of decreasing wellbore inefficiencies by improving the procedures quality. Thereby, providing appropriate parameters such as safety, boosting the drilling speed and enrolling the proper procedure of optimizing performances of high activity water-sensitivity formation should be taken into consideration. The objective of this comprehensive study is to apply experimental evaluation tests on the shale inhibitor fluids by using prepared plug samples from the studied field due to the administration of pore pressure transmission (henceforth, PPT) equipment. Even though, PPT equipment is not able to simulate all the mechanisms which are applied to different drilling fluids on the shale layers’ stability, it will control such parameters like the penetration of fluid filtration through the formation that subsequently reduce the wellbore problems. Consequently, the ubiquitous use formate fluid in drilling operations of exploratory oil wells in the studied field is successfully implemented to be addressed the current well inefficiencies adequately.
