Abstract

Federal regulations mandate that fully functional safety valves be installed and regularly tested in all producing wells in the Gulf of Mexico. Over the life of an oil and/or gas well, deposit build-ups can occur in the safety valves, sliding sleeves, and throughout the tubing of the well. Currently, the only reliably safe way to remove or mitigate these deposits is to displace the whole tubing volume with a weak solution that will react and dissolve the build-up. Build-ups are prevalent around turbulent flow areas such as safety valves and sliding sleeves. The smallest amount of scale, cement, paraffin or any debris build-up can render mechanical devices inoperable. This can lead to forced operations that cause formation damage, pulling a whole completion string, or ultimately a loss in valuable production time.

Description

The Soak-A-Spot is a tool that will store any amount or type of highly concentrated fluid needed to diminish or eradicate the specific spot that has a build-up at a sliding sleeve, safety valve or other devices throughout the completion tubing.  The Soak-A-Spot can be run in one trip while the gas, oil or gas/oil well is under pressure with electric line or slick line. 

The requirements that must be present in the tubing string to operate the Soak-A-Spot are a nipple profile directly above and a polished bore directly below the desired spot that will be treated in a well.

 In summary, it is pretty much a large syringe that is run in the hole to a certain depth and then the fluid is released with one smooth motion.  This tool would be great to patent, but it would be just as great to patent the “...
