Shale Gas WCPM™ ServiceDec 01, 2014
PROJECT CHALLENGE
ENTI undertook the single well construction engineering for PetroChina in a key shale gas research area at Luzhou, Sichuan, China. The TVD was to be about 2,300m and the reservoirs penetrated were the Longmaxi and Wufeng formations. As it was the first exploration well in the area, there was very limited data to consult.

SOLUTIONS
ENTI set up the SIS-11 project team to liaise with the customers’ co-opteam. Through effective management,resource integration, efficient operation and the shale gas drilling and completion experience obtained in North America and Sichuan, an efficient WCPM™ service was achieved.
 
ACHIEVEMENTS
The well construction period was reduced by 50% compared to surrounding exploratory or evaluation wells and represented the best performance in the area. A stable production rate was obtained by using ENTI-101 proppant and ENTI-30 slick water.
