Xanvis

Product #21700

Xanvis is a clarified, completion grade, xanthan biopolymer to be used as a premium viscosifier particularly for use in production zones. Horizontal wellbore simulations show that when flow is initiated, settled solids tend to move along the bottom of the hole as waves or dunes. These solids build up can result in increased torque, drag and the inability to transfer weight to the bit.

Xanvis provides optimum cleaning characteristics in horizontal hole sections. In addition to providing excellent rheology for hole cleaning while drilling, Xanvis provides for exceptional suspension of solids during non-circulating periods. These properties cannot be properly described using conventional Fann viscometers.

The optimum concentration of Xanvis is 2.8-8.5 kg/m³ depending upon the application.
