A producer in southwest Wyoming was experiencing severe hydrate problems in one of their gas wells. The problems were so severe that the well was shut-in more than it was producing. Continuous injection of methanol failed to control the problem and bring the well’s production to its projected capacity. It was difficult to travel to the remote location to service the well, making it nearly impossible to keep the well running continuously and efficiently.

As a result, the customer experienced high maintenance costs, production losses due to downhole hydrate deposition, excessive engineering time to resolve the problem, and poor production performance. Additionally, methanol inventory was extremely difficult to maintain in this remote location. Remediation of the hydrate plugs also caused safety and environmental concerns.

Baker Hughes, a GE company (BHGE) assessed the problem using hydrate modeling techniques and simulations. Experts determined that insufficient amounts of methanol were being used, and they calculated the amount of methanol necessary to adequately resolve the hydrate deposition problem. They also determined that FORSA™ HIW5557 low-dosage hydrate inhibitor (LDHI) was the best product to use in conjunction with the methanol. This combination resulted in a super-charged methanol/LDHI that proved highly successful for the customer.
