Schlumberger uses AgCenter invention in drilling expedition in Vietnam

(07/19/16) BATON ROUGE, La. – A leading oilfield services company has used an LSU AgCenter invention to help stop fluid from leaking while drilling two deepwater wells off the coast of Vietnam.

TigerBullets – a product created by Qinglin Wu, a professor in the AgCenter School of Renewable Natural Resources – was used in the drilling expedition that Schlumberger Limited began in August 2015. TigerBullets are owned by the AgCenter and licensed to Hole Pluggers, LLC.

TigerBullets are made from plastics, wood scraps, minerals and other additives that are pressed into pellets that stop lost circulation, a major and costly problem when drilling oil wells. Lost circulation refers to the leakage of drilling fluid through cracks in the well.

Lost circulation is typically addressed by pumping material into the well to fill any cracks. When TigerBullets are used, they absorb water and expand, locking them into the fracture to cut off any leaks.

All materials used in TigerBullets are recycled, biodegradable, partially acid-soluble and non-toxic.
