Assessment of efficiency of usage of different types of drilling muds in unstable clay deposits of Kyrtael field
Assessment of reservoir material regarding effectiveness of usage of different types of muds in Kyrtael field was made. Simulation of a simple crack by means of BCB-25 provided assessment of muds’ influence on inner mesh in the rock massif was performed. Calculation of economic effect reached due to usage of silicate polymer-clay mud is carried out.
