BAROID FLUID HELPS OPERATORS
TO DECREASE NON-PRODUCTIVE TIME RELATED TO STUCK PIPE
Houston, Texas - Baroid, a Halliburton (NYSE: HAL) product service line, has developed a spotting fluid, QUIK-FREE™, which is designed to free differentially stuck pipe.
Stuck pipe can be a major source of non-productive time during drilling operations. When the problem occurs, timely removal of the pipe is important since every minute that the pipe remains stuck increases the likelihood that the operation will end up as an expensive, time-consuming "fishing job."
QUIK-FREE spotting fluid can be mixed and placed rapidly because it requires none of the additives typically associated with an invert emulsion spotting fluid. On average, it shows significant results four to six hours after it is placed downhole. Other spotting fluids can require up to 24 hours of soak time.
"QUIK-FREE spotting fluid works by breaking the capillary forces holding the pipe against the wellbore wall," said Tom Carlson, Technology Leader, Solutions Group, Halliburton Energy Services Group. "The wallcake dehydrates and shrinks, allowing the pipe to be worked free. After the pipe is free, the QUIK-FREE spotting fluid can be incorporated into an active water-based drilling fluid system, because its environmentally-friendly composition doesn't require capturing and disposing of the fluid."
On a disposal well in Louisiana, QUIK-FREE spotting fluid was able to save an operator approximately two days of rig time plus an estimated $50,000 "fishing job." On the project, the
drillstring became stuck in a 12 ¼ -inch hole at 4,022 feet measured depth with no up or down movement. After 12 hours of trying to free the pipe, a nine pounds per gallon (ppg) QUIK-FREE spotting fluid was pumped into the stuck zone. After a five-hour soak period, the pipe could be moved downward 14 feet. For the next 20 hours, one barrel of QUIK-FREE spotting fluid was pumped each hour. At this point circulation was established to wash the dehydrated filtercake from around the pipe, after only 15 minutes of circulation the pipe became free. The entire volume of QUIK-FREE spotting fluid was then incorporated into the active polymer system with no adverse affect on the fluid properties.
QUIK-FREE spotting fluid is compatible with fresh and salt water drilling fluids and can be incorporated into active mud systems without adverse effects on any of the properties.
