OSP 2K7 WATER SOLUBLE PAKS REDUCE BACTERIAL LOAD IN COILED TUBING FLUID IN THE EAGLE FORD

Background

Coiled tubing (CT) is used for a variety of operations in oil and gas wells, including mill out of bridge plugs after cemented liner plug-and-perf stimulation. With each trip in or out of the wellbore, the CT string incurs a certain amount of fatigue that can be estimated using simulation software based on the CT outside diameter (OD) and material grade. CT units are retired at 80% of predicted fatigue. CT manufacturers have increasing empirical evidence showing that CT units experience premature string failures (below 80% fatigue) in certain areas, such as the Eagle Ford, Haynesville formations and Permian basin in Texas, and the Horn River and Montney formations in northern British Columbia. These string failures manifest in the form of pinholes and parting of the pipe. If these failures occur above ground, safety risks are a major concern. If they occur downhole, as detected by a sudden drop in tubing weight, the project is delayed and the costs of fishing out the broken pipe is incurred as well as the loss of the CT unit for future operations.
