A recently completed high pressure/high temperature well in the Gulf of Mexico, was brought on production but held back to low drawdown due to sand control integrity concern and remained shut in.
Traditional sealing technologies although capable of isolating flow inside the base pipe of the sand screen is not able to isolate the annulus. Three further attempts were made with such tools to establish solids (sand) free rate – all were unsuccessful.
BiSN’s Wel-lok™ SCT (Sand Control Tool) provides a novel solution to seal off the annulus behind the sand screen by flowing molten bismuth alloy through the sand screen and gravel pack thereby completely sealing off any flow of solids (sand) from zones below.
We helped bring the well back into production and increased production.
