Zusammenfassung:	A method for servicing an offshore well having a subsea blowout preventer. A sealing nipple having a wireline extending therethrough and connected to a servicing tool is lowered into the well and sealed by sealing rams of the blowout preventer. After the sealing rams are closed about the sealing nipple, the well can be pressurized through a fluid line extending to a work area. The method is particularly useful for pressurizing a cased well to eliminate any microannulus between the well casing and cement surrounding the casing prior to running a cement evaluation logging tool through the well.
