Drilling optimization: An approach using membrane technology

J. K. Adewole, King Fahd University of Petroleum & Minerals, Saudi Arabia

During drilling, the invasion of drilling fluid particles into the formation can be described as a lateral movement of suspended particles into porous formation which acts like a sieve for the suspended particles. These particles are captured near the wellbore surface and accumulate as filter cake. The mechanism of cake formation and growth is majorly controlled by forces which are dependent on particle diameter, shape, and fluid properties. The quality of the filter cake constitutes an important factor in its ability to prevent formation damage and wellbore instability. In this paper, research efforts to understand the transport properties of solutes and ions (that are contained within the drilling fluid) into the drilled formation are discussed. The results of this work are expected to provide some insights that are needed for designing better drilling fluid formulations for challenging environment.
