DESIGN METHODOLOGY FOR ELIMINATING ABSORPTION OF FLUSHING FLUID IN WELL CONSTRUCTION

Abstract

The objective of this work is to enhance the efficiency of zonal isolation operations through the application of thermoplastic mixtures for mitigating drilling fluid losses (lost circulation) during well construction. The outlined tasks were addressed using a comprehensive research methodology, which included the analysis and synthesis of literary and patent sources, alongside analytical modeling and experimental studies.

This research further advances the theory of mitigating lost circulation during well construction. It provides a substantiated sequence of technological operations for eliminating drilling fluid losses in the wellbore. The prospective utility of the proposed approaches for developing novel technological solutions is demonstrated.

The obtained results establish a foundation for: 1) developing more advanced technologies for sealing off lost-circulation zones; 2) designing new materials utilizing phase transition phenomena of the sealing compound; 3) manufacturing novel thermoplastic sealing materials; 4) formulating a technical specification for the isolation of thief zones.
