Patent number: 10928537Abstract: An embodiment of a method of predicting a location of one or more features of an earth formation during a downhole operation includes acquiring reference data and identifying one or more reference data sections, each reference data section corresponding to a feature of interest and having an associated depth or depth interval, deploying a drilling assembly and drilling a target borehole in the earth formation, and performing measurements during the operation by a downhole measurement device to generate measurement data. The method also includes performing one or more correlations of the one or more measurement data sections with one or more reference data sections; and predicting at least one of a depth of a subsequent feature of interest located beyond a current carrier depth and a point in time of a future event associated with the subsequent feature of interest based on the correlation.Type: GrantFiled: July 2, 2020Date of Patent: February 23, 2021Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Anne Bartetzko, Stefan Wessling

Patent number: 9157316Abstract: A method and apparatus for estimating a pressure transition zone in a borehole is disclosed. A parameter indicative of formation fluid pressure at a plurality of borehole depths is measured. A global trend of the parameter is determined over a first depth interval and a local trend of the parameter is determined over a second depth interval. A relation is determined between the global trend and the local trend, and the pressure transition zone is determined from the determined relation between the determined global trend and the determined local trend.Type: GrantFiled: January 27, 2012Date of Patent: October 13, 2015Assignee: Baker Hughes IncorporatedInventors: Stefan Wessling, XiaoWei Wang, Anne Bartetzko, Jianyong Pei
