Effect of Drag Reducing Agent on Core Sample in Injection Well

The usage of sea water treated with Drag Reducing Agent in injection well has become
phenomenon in oil and gas industry. Numerous case studies have reported the successful
story of the ORA usage in order to maximize injection rate. Using ORA as additive in
injection water was believe can increase the injection rate, increase the production rate,
extend the field life, reduce energy cost. Several studies have proven that ORA only reduce
the permeability of core with very small amount and can be negligible. However, there are
lack of study on specific effect of Polyacrylamide DRA was conducted. Previous study
mostly did not mention specific type of ORA that they used. This project was setup in
objective to study the effect of Polyacrylamide, water-soluble polymer. This project will
study the effect of Polyacrylamide on core sample in term of permeability losses. Apart from
that, this project also will study the method the recover the permeability losses. Project
methodology and activities also included. The project experiment design and procedure is
explained. All the result data, analysis and findings presented at the end of this report.
