This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 197774, “Improvement in Rheological Features, Fluid Loss, and Swelling Inhibition of Water-Based Drilling Mud by Use of Surfactant-Modified Graphene,” by Azeem Rana and Tawfik A. Saleh, King Fahd University of Petroleum and Minerals, and Mohammad K. Arfaj, Saudi Aramco, prepared for the 2019 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 11-14 November. The paper has not been peer reviewed.
This paper reports the effect of sodium dodecyl sulfate modified graphene (SDS-Gr) on the rheological features, fluid loss, and swelling inhibition mechanism of clay. The outcomes revealed that the addition of SDS-Gr to traditional drilling mud clearly affects the rheological properties, increasing its suitability for drilling. Moreover, SDS-Gr additive reduces fluid loss by 20% compared with the mud without SDS-Gr.
