Comparative Experimental Investigation of Surfactant Performance for Improved oil recovery by unloading the Wells

Abstract

This research paper analyses the potential for surfactants to lessen this frequent industry difficulty by delving into the complicated world of liquid-filled gas wells. The major goal is to clarify the intricacies of liquid buildup from gas wells by making use of sodium dodecyl sulfate's (SDS) effectiveness as a potent surfactant. SDS emerged as a suitable choice after thorough testing and analysis, demonstrating impressive effectiveness in lowering surface tension and aiding the separation of trapped liquid from the well surface. Research also explores the topic of carrier fluids, looking into how they can improve the efficacy of surfactants. In a significant development, studies have shown that the condensate looks to be a highly efficient carrier fluid due to its compatibility with SDS and its innate capacity to suppress foaming. This special mixture guarantees the surfactant's ideal dispersion and interaction with the collected liquid, which enhances the unloading procedure.

The study then broadened its reach by outlining and meticulously analyzing various injection techniques. These include the coil injection and annular approaches. Utilizing this multifaceted approach, the study thoroughly evaluated the inherent advantages and disadvantages of each methodology. These evaluations offer very significant information that enables a thorough comprehension of their individual advantages and difficulties. The combined findings of this research make a substantial contribution to our comprehension of the intricate interactions between surfactant, carrier fluid, and various injection strategies.

This thorough understanding, which was developed by combining theoretical knowledge with empirical analysis, should pave the way for the creation of sophisticated solutions to address one of the complex problems—the problem of fluid loading into gas wells.
