Enhanced Oil Recovery By Polymer Injection

Enhanced Oil Recovery by polymer injection

Polymer to control the mobility of injected water has been employed for many years in Enhanced Oil Recovery (EOR) applications.

Polymer flooding to improve volumetric sweep efficiency and reduce channeling and breakthrough, has been used by many operators to increase oil recovery. The same polymer can also be used with surfactants and alkali agents to increase the sweep efficiency of these tertiary recovery floods (i.e., ASP, SP and AP). Polymer flooding can yield a significant increase in oil recovery when compared to conventional water flooding techniques. A typical polymer flood project involves mixing and injecting polymer over an extended period of time until a slug volume equal to about 1/3 of the reservoir pore volume has been injected. This polymer slug is then followed by continued long term water flooding to drive the polymer slug and the oil bank in front of it towards the production wells. Polymer is injected continuously over a period of years to reach the desired injected pore volume. The end result being more oil produced in less time.

Worked up this illustration of a couple I saw on the train a few weeks back… I embellished a little on the design; the guy didn’t have this body frame, & neither wore gold, but both carried a powerful sense of African pride about them, which I loved… People couldn’t take their eyes off them… I loved that too.

Whoa. For The First Time Ever, A Victoria’s Secret Model Walked The Runway With Natural Hair. Rather

Whoa. For the first time ever, a Victoria’s Secret model walked the runway with natural hair. Rather than bending to VS’s traditional beauty standards, 23-year-old Angolan model Maria Borges rocked the runway sans wig, weave or even extensions. For Borges, it was a history-making in a personal way.

The Night Before Herod Was To Bring Him To Trial, Peter Was Sleeping Between Two Soldiers, Bound With

The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance. Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and the chains fell off Peter’s wrists.

Acts 12:6-7 (NIV)
