Acidizing/stimulation

Reservoir Stimulation Technique Combines Radial Drilling Technology With Acid Jetting

The authors describe a carbonate reservoir stimulation technique able to deploy acids in the rock far away from the wellbore through mechanically drilled holes with known depths and azimuths.

The complete paper describes an approach to stimulate carbonate formations with bedding water or a gas cap. The technique is a combination of acid jetting and a radial drilling technology that uses mechanical radial drilling with a slim mud motor. The primary advantages of the technology include controlled trajectory and the possibility of re-entry into channels. The novelty of the technology is in its ability to deploy acids in the rock far away from the wellbore through the mechanically drilled holes with known depths and azimuths.

Reservoir Description

The mature field is in central Russia in the Republic of Bashkortostan.
