Patent number: 11946360Abstract: Stratigraphic analysis includes determining misfit values between stratigraphic vertical depth of an offset wellbore, SVDow and measured depth of a subject wellbore. A likelihood that the target measured depth is equal to or within a tolerance of stratigraphic vertical depth of the subject wellbore, SVDsw, for sequences of stratigraphic vertical depth is calculated. A probability weighted average and an uncertainty that the target measured depth for the subject wellbore, TMDsw, is equal to or within a tolerance of stratigraphic vertical depth of the subject wellbore, is calculated. A continuous probability function over a range of measured depth that the target measured depth for the subject wellbore, TMDsw, is equal to or within a tolerance of stratigraphic vertical depth of the subject wellbore, SVDsw, is calculated.Type: GrantFiled: May 7, 2020Date of Patent: April 2, 2024Assignee: Magnetic Variation Services, LLCInventors: Stefan Maus, Alexander Michael Mitkus, Timothy William Gee

Patent number: 11941831Abstract: An image processing system to estimate depth for a scene. The image processing system includes a fusion engine to receive a first depth estimate from a geometric reconstruction engine and a second depth estimate from a neural network architecture. The fusion engine is configured to probabilistically fuse the first depth estimate and the second depth estimate to output a fused depth estimate for the scene. The fusion engine is configured to receive a measurement of uncertainty for the first depth estimate from the geometric reconstruction engine and a measurement of uncertainty for the second depth estimate from the neural network architecture, and use the measurements of uncertainty to probabilistically fuse the first depth estimate and the second depth estimate.Type: GrantFiled: July 23, 2021Date of Patent: March 26, 2024Assignee: Imperial College Innovations LimitedInventors: Tristan William Laidlow, Jan Czarnowski, Stefan Leutenegger

Patent number: 11920441Abstract: Systems and methods for using stratigraphic heat maps to steer a well being drilled. Data from one or more offset wells can be provided to a computer system and used with data from a well being drilled to generate one or more stratigraphic heat maps during the drilling of the subject well. The stratigraphic heat maps can be displayed and used to determine the location of the wellbore relative to one or more geological formations, including one or more target formations or within a target formation. Based on the use of the heat maps and the location of the wellbore relative to a target, the drill plan can be adjusted or updated and/or one or more drilling parameters or operations may be adjusted to drill the wellbore, such as to drill the wellbore to the target or to maximize the length of the wellbore within a target zone.Type: GrantFiled: March 17, 2020Date of Patent: March 5, 2024Assignee: Magnetic Variation Services, LLCInventors: Timothy William Gee, Stefan Maus, Kenneth Robert McCarthy, Alexander Michael Mitkus, Jin Sun
