MICRO-CURE E2 restored production and extended well life
An operator in the Rio Viejo field in California had an oil well that was underperforming. The company was concerned that the reduced production was due to near-wellbore emulsion blockage induced by wellbore fluids during workover operations.
A pressure build-up (PBU) analysis identified positive skin damage of +22 S. An initial PBU analysis conducted prior to the workover operation had showed skin damage of only +2 S. The company confirmed the damage was due to a wettability issue and/or emulsion blockage caused by the previous workover operation.
The distributor in charge of the project proposed the MICRO-CURE™ E2 remediation system from Baker Hughes, a GE company (BHGE), to remove the emulsion/water blockage, convert the completion to a water wet environment, and solubilize any calcium carbonate deposits that might be present.
