PDO Nimr Polymer Commissioning & Start-up

PDO built a new Polymer Injection Trial Facility at Nimr-E for Polymer Flood Trials in the Nimr E oilfield for Enhanced Oil Recovery (EOR) for 3 to 6 years with the intention to relocated to other oilfield locations because of the close proximity of the producer-injector wells separation.
Polymer Flood Trial Facilities at Nimr-E used Stabilized Polymer in powder form that had to be mixed with water to make polymer at a controlled viscosity. This polymer was mixed with water at the injection pumps.

Commissioning was the execution of all the functional checks & tests proving that operational activities can be executed.
Start-up included performance test of Water & Polymer Injection the Facility.
The initial operations phase commenced after successful performance test run of Water and Polymer Injection including utilities and as followed by process optimisation and training.
