State of the Art and Future Trend of Drilling Fluid: An Experimental Study

Abstract

AbstractIn its endeavor to provide a sustainable flow of hydrocarbon energy, the Petroleum industry has been recognized by the general public as an industry that has negatively impacted the environment as a result of using either harmful materials or risky practices. This leads the industry to continuously invest in R&D to develop environmentally friendly technologies and products. For any new technology or product, the current R&D trend is toward the development of sustainable practices and expertise. Drilling fluids are necessary for drilling oil and gas wells. Unfortunately drilling fluids have become increasingly more complex in order to satisfy the various operational demands and challenges. The materials used in the process to improve the quality and functions of the drilling fluids, contaminates the subsurface and underground systems, landfills, and surrounding environment. Due to the increasing environmental awareness and pressure from environmental agencies throughout the world it is very important to look back to the drilling fluid technology to reassess its progress. To sustain its position as an environment friendly industry, the petroleum industry should make forward steps to improve its practices. This article outlines the state-of-the-art of drilling fluids. The major types of drilling fluids, their strengths, limitations, and remedies to limitations are discussed. It also presents the current trend and the future challenges of this technology. An experiment was conducted to develop an environment friendly drilling fluid which is found more convenient and user friendly based on sustainability concept. The results of the experiment show that 90/10 oil water ratio formulation has higher probability to consider as a sustainable drilling mud. In addition, future research guidelines are presented focusing on the development of environmentally friendly drilling fluids with zero impact on the environment. The paper concludes that future trend leads toward the development of sustainable drilling fluids.
