CNPC AktobeMunaiGas Maps Reservoir and Exceeds Production Expectations with PeriScope HD Service

Publication Date: 01/30/2017

CNPC AktobeMunaiGas (CNPC AMG)—with Vostokneft and Anton Oilfield Services Group— planned to place a long horizontal section in a target layer with an undulated reservoir cap resulting from formation erosion. The extended lateral length and limited rotating speed indicated a high risk of packoff. The operator was also challenged by ineffective WOB transfer because of potential drillstring buckling in the curve interval. Throughout drilling, abrasive dolomite intervals negatively impacted bit lifecycle and ROP. CNPC sought to overcome these challenges by mapping the reservoir and placing the well precisely, achieving continuous WOB transfer and increasing ROP and bit life.
