Attapulgite Clay for Drilling Mud (BT-Z)
Decription: Salt Gel attapulgite clay is an effective viscosifier for all water-base systems, including those made up with brackish water, seawater and saturated salt water.
Applications: Salt Gel requires mechanical shear and agitation for maximum viscosity. It is not a hydratable clay and does not swell by adsorbing water to create viscosity. Salt Gel provides viscosity by the physical nteraction of its rod-like particles.
A high-fluid-loss, Salt Gel squeeze can be formulated for combating lost circulation. It can be spotted opposite the loss zone, and light squeeze pressure can be applied to deposit a high concentration of solids. For bridging larger fractures effectively, fibrous and/or granular lost-circulation materials can be incorporated into the slurry. Salt Gel slurries can be formulated in fresh or salt water and can be weighted or unweighted.
