The Baker Hughes DELTA-SEAL™ wellbore sealing polymer is specially designed to disperse into unique sub-micron-sized particles when added to drilling fluid system. Delivering advanced performance in a variety of drilling conditions, DELTA-SEAL has a wide range of synergistic applications and attributes to overcome wellbore instability and weak formation challenges.
The DELTA-SEAL sealing polymer is compatible with invert emulsion drilling fluids, freshwater, and salt-saturated water-based fluids. When used in combination with sized synthetic graphitic products such as the LC-LUBE™ additive, the DELTA-SEAL sealing polymer is very effective at sealing porous, highly permeable formations. This reduces the potential for induced fractures thereby minimizing the risk of differential sticking and/or downhole losses.
