Method for enhancing gas well secondary recovery operations

机译:一种提高气井二次采收率的方法

摘要

The present invention relates to a process and system for the remediation and enhancement of secondary recovery gas from a natural gas well and geologic formation. The present invention employs the use of protic and aprotic solvents which are injected in sequence into the well and geologic formation. The protic and aprotic solvents are injected into the well bore and progress through the geologic fissures and pores of the geologic formation. After reacting with the downhole and geologic formation deposits, the solvent solute, containing the remaining solvent, dissolved solids and debris, and any remaining components are extracted from the well and formation resulting in improved gas well flow rate through the formation and well bore.
