Patent number: 10865608Abstract: A mobile offshore drilling unit is converted to provide drilling, completion and workover access to multiple dry tree wells from a drilling derrick to allow production and export of oil and gas from high pressure, high temperature reservoirs in deep offshore waters. Existing practice has been for the drilling derrick on a production platform supporting dry tree wells to be moved over a fixed well slot. The present invention provides a movable wellbay that supports multiple top-tensioned subsea well tieback risers, which may be positioned directly below the derrick's rotary table and/or beneath another operating device. The use of top-tensioned subsea well tieback risers supported by the movable wellbay allows the converted facility to drill, complete, maintain, improve and produce from subsea wells through dry trees.Type: GrantFiled: September 30, 2019Date of Patent: December 15, 2020Assignee: FRONTIER DEEPWATER APPRAISAL SOLUTIONS LLCInventors: Roy B.

Patent number: 5615115Abstract: A method of generating a two-dimensional pore pressure gradient and fracture gradient cross section from seismic survey data is disclosed. In general, the method includes generation of a two-dimensional overburden gradient cross section and a two-dimensional normal compaction trend line cross section. The two-dimensional overburden gradient and normal compaction trend line cross sections are preferably generated by extrapolating the overburden gradient and normal compaction trend lines at an existing offset well, after correlating seismic interval transit times to the density and well log data at the offset well location. Once the two-dimensional overburden gradient cross section and two-dimensional normal compaction trend line cross section are generated, the Eaton method is applied at each of the common depth points of interest to produce a two-dimensional pore pressure gradient cross section, at least at certain common depth points of interest.Type: GrantFiled: December 15, 1994Date of Patent: March 25, 1997Assignee: Atlantic Richfield CompanyInventor: Roy B.
