International cooperation projects: including cooperation with internationally renowned oil and gas companies such as Shell and Chevron in the field of drilling and completion fluids in China

SHELL SICHUAN SHALE GAS PROJECT

From 2011 to 2014, we provided on-site technical services for polymer water-based drilling fluids and synthetic drilling fluids for over 30 wells. The upper well section adopts water-based drilling fluid technology with high environmental acceptance and biodegradability, combined with the use of barite recovery system to remove medium and low density solids, achieving efficient utilization of drilling fluid. The lower section adopts synthetic drilling fluid technology to under balance or balance drilling with lower drilling fluid density, which is conducive to timely discovery of reservoirs and protection of oil and gas reservoirs. The first batch of onshore oil based drilling fluid recovery and treatment plants (Shehong Mud Station) of PetroChina have been built, achieving full reuse of oil based drilling fluids and achieving the HSE goal of "non-emissions and non-pollution".
