Polymer Backproducing ESP
Chemical Enhanced Oil Recovery - here Polymer Flooding - still seems to be a niche reservoir technology in the petroleum business. Mainly used for brown fields, polymer floods are designed to change the flow paths in the reservoir and push the remaining oil towards the producers. What sounds like an idea easily to be handled, may represent major challenges once it comes to the production side.
How we can support you:
In some chemically flooded fields, Electrical Submersible Pumps are selected to back produce the injected polymer solution. Depending the reservoir conditions, this solution may have even initial fluid properties and therefore can represent a challenge for the pump. Since ESPs are sensitive to changes in production environment, their design needs to be carefully harmonized with the expected properties of back produced fluids over time.
Our team is supporting you also here along the whole lifecycle – from the first entry of polymer solution into the borehole until it reaches the separator. We are familiar with typical production challenges of various polymer floods around the world and what it needs to design and operate a resilient polymer back producing ESP.
