Patent number: 11898444Abstract: Contamination estimation of a mud filtrate or reservoir sample requires a robust handle on the properties of mud filtrate at downhole conditions. Coupling acquired data with downhole measured data provides a robust estimation of contamination by encompassing the entire available data. Downhole density of the mud filtrate sample may be estimated based on a characteristic of the mud filtrate sample. A density of a formation fluid of the reservoir may be determined using a formation tester tool. The contamination of the formation fluid may be estimated based on the clean fluid density and the estimated mud filtrate density by, for example, using a material balance equation or ratio. An estimated pump-out time for the formation fluid may be determined based on the estimated contamination and a trend of the estimated contamination of the formation fluid.Type: GrantFiled: June 9, 2021Date of Patent: February 13, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Waqar Ahmad Khan, Mehdi Azari, Abbas Sami Eyuboglu

Patent number: 11761298Abstract: A location of a cut and an amount of force to be used in a pull operation for a plug & abandonment (P&A) operation can be determined. Measurements of at least one characteristic of fluids and solids disposed in an annulus defined between a casing and a wall of a wellbore can be received. A total fluid and solid friction force drag can be determined using hydrostatic force that is determined from the measurements. A mechanical friction force drag can be determined based on a weight of the casing. The mechanical friction force drag and the total fluid and solid friction force drag can be used to determine a friction factor. The friction factor can be used to determine a depth location at which to cut the casing and a pull force for pulling the casing from the wellbore in the P&A operation.Type: GrantFiled: August 30, 2021Date of Patent: September 19, 2023Assignee: Landmark Graphics CorporationInventors: Robello Samuel, William Wade Samec, Roddy Hebert, Robert H.

Patent number: 10012761Abstract: A computer accepts dead-oil properties of a reservoir fluid sampled from a well. The dead-oil properties are the measured composition of the reservoir fluid after volatile components of the reservoir have substantially vaporized. The computer analyzes the dead-oil properties and a constraint to produce estimated live-oil properties of the reservoir fluid. The live-oil properties are the composition of the reservoir before the volatile components have substantially vaporized. The computer uses the estimated live-oil properties to make a decision regarding the well.Type: GrantFiled: October 27, 2010Date of Patent: July 3, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Christopher M.

Patent number: 9310508Abstract: Various logging-while-drilling (LWD) systems and methods provide resistivity logging coupled with deep detection of elongated anomalies at acute angles, enabling effective geosteering without disrupting drilling operations and without requiring intervention in the operations of the existing well. One LWD system embodiment employs a tool having tilted antennas as the transmitter and the receiver, where at least one of the antennas is placed in the vicinity of the bit, making it possible to detect existing wells at distances of 50-100 feet. In some cases, the detection distance is increased by enhancing the visibility of the existing well using a contrast fluid treatment on target well, either to fill the bore or to surround the well with treated cement or fluids that invade the formation. At least one inversion method separates the inversion of formation parameters from the inversion of parameters specifying distance, direction, and orientation of the existing well.Type: GrantFiled: June 29, 2010Date of Patent: April 12, 2016Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Burkay Donderici, Abbas Sami Eyuboglu, Michael S.
