Following approximately 800 galUS [3,032 L] of the viscosifier being pumped, drilling resumed and torque decreased from 3,000 psi to 1,500 psi [20.7 MPa to 10.3 MPa] and the well was drilled to planned TD successfully. The DRILPLEX HDD viscosifier achieved hole cleaning and target viscosity, holding the gravel in place.

Background

When Schlumberger learned an operator was concerned about hole cleaning and packing off in a key drill hole being cored from surface, DRILPLEX HDD viscosifier was recommended by M-I SWACO, a Schlumberger company, for its properties of highly shear-thinning ability and ceasing to flow as it enters fractures of spaces between the rock.
