Production Problems Solving Well Stimulation and Field Problems

Course Description

T

he course is designed for engineers who deal with well performance enhancement. The course will go through various techniques that can be used to enhance productivity of oil and gas wells. This is followed by overview of acid and hydraulic fracturing, matrix treatments for carbonate and sandstone formations. Issues related to candidate selection, treatment design, selection of acid additives, lab testing, acid placement, QA/QC, job execution, and treatment evaluation will be discussed in detail. The course will end with introducing new technologies for carbonate and sandstone acidizing. Field cases will be given to highlight problems and how lab testing was used to find cost effective solutions to these problems.
