Title : Recent advances in polymer utilization for deep foundation in oil and gas
Abstract:
Solutions of water-soluble polymers are novelly developed, and most diverse viscous fluid type for challenges posed in oil–gas drilling and production. With advantages of enhancing rheology, filtrate generation, cuttings transportation, and fluid lubricity, the polymer drilling fluid is gradually replacing the oil-based drilling fluid. This investigation provides an overview of the challenges encountered in drilling and how polymers can help overcome these challenges. In contrast, this research investigates the intricacies of establishing foundations in demanding soil conditions, emphasizing contemporary practices.
In this context, SNF has devised internal laboratory tests dedicated to selecting the ideal perforation fluid formulation tailored to the encountered soil conditions in oil–gas drilling. The investigation covers perforation in diverse environments such as sandy soil, gravel soil, non-stable soil, salty water, and brines. The findings from these studies inform the design of effective drilling fluids and appropriate additives. The research also delves into the examination of viscosity, filter loss, and fluid loss, employing the guidelines of API 13A & B-ISO 10414-1, complemented by specifically designed SNF test procedures.
