Completion Fluids Filtration

Why filtration of completion fluids

The purpose of filtering completion fluid or well bore clean up fluids, also known as brine is to prevent the downhole contamination of the formation. Contamination reduces production and shortens the productive life of the well. Contamination can occur during perforating, fracturing, acidizing, workover, water- flooding, and gravel packing as well. Any time fluid is put into the well bore with a solid content, no matter how slight; there is a chance of damaging the well. A fluid contaminant can come in many sizes and forms. Drilling operations produce cuttings, rust, scale, pipe dope, paraffin, undissolved polymer, and other material on the casing or pipe string. All these materials contribute to the amount of solids in the fluid.

Effective filtration service requires a cooperative effort on the part of all those involved in drilling and production, so that formation damage can be minimized. In the past, operators have generally tried to have clean, solids-free fluids in the well bore before perforating intervals. Porous and permeable rock acts like a deep bed filter for suspended particles, and even a solids-free fluid may damage a formation if not chemically compatible with the formation rock. Filtration has evolved from old surface filtering systems with low flow volume to highly sophisticated systems. Although filtering can be expensive and time consuming, a case for filtering fluids can be made for every completed well and workover where the net production has been increased more than enough to pay for the difference.
