摘要:
The present invention provides methods and apparatus for obtaining downhole well pressure during wellbore operations. One method comprises providing a well intervention tool comprising a straddle sealing assembly having upper and lower annulus sealing elements and a fluid injection port positioned therebetween, the well intervention tool comprising a fluid injection bore having positioned therein a pressure measurement tool; placing the tool in straddle position about a wellbore region to be intervened, with the pressure measurement tool fluidly connected to a wellbore region below the lower annulus sealing element; and performing the wellbore intervention operation while communicating fluid from below the lower annulus sealing element to the pressure measurement tool, thus obtaining a pressure measurement below the lower annulus sealing element during the wellbore intervention operation. This abstract will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
