Oil pools developed by PJSC «Tatneft» are mainly confined to the Devonian deposits, the top of which is represented by Kynovsk argillites. The construction of a horizontal wellbore in the Upper Devonian terrigenous strata (D0) is complicated by the geological structure of this complex, which leads to complications related with maintaining aborehole stability. The results of the proposed complex drilling fluid AGNI-Drill study prove its effectiveness in drilling wells to the complicated areas.
