Paper: Crystal Modifier Project

The Midway FMT is a Spraberry waterflood located in Dawson County about 10 miles southeast of Lamesa, Texas that has a history of paraffin problems. The severity of problems range from having to abandon flowlines that plugged with paraffin, to back pressure on flowlines, to reduced production rates, to having to hot oil or hot water flowlines, to injecting paraffin solvents and paraffin inhibitors and / or combinations of the above. Paraffin build-ups in tubing can result in decreased flow rates, expense and delayed production due to field or contract wireline cutting and steaming the tubing. The goal of the Midway FMT is to maximize production while investigating ways to reduce controllable expenses through chemicals and associated costs. This paper describes a method to help control paraffin using a chemical program developed by Unichem called the Crystal Modifier Project. The objective of this program is to reduce failures and costs associated with paraffin.
