Patent number: 11579329Abstract: Estimating wear on bottom hole assembly (BHA) components utilizes a rock hardness index using analysis of drill cutting. Estimating the amount of wear on borehole assembly components comprises measuring the rock properties in drilled cuttings from a borehole. A hardness value is assigned to each mineral present in the drilled cuttings. A hardness index is calculated for a drilled borehole interval. A wear resistance factor is assigned to each BHA component of the BHA. The wear resistance factor depends on the wear resistance of each BHA component. A wear value for each BHA component is calculated based on the hardness index for the drilled borehole interval, the wear resistance of the BHA component, and drilling parameters.Type: GrantFiled: June 5, 2020Date of Patent: February 14, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Ian David Campbell Mitchell, Crystal M.

Patent number: 11193341Abstract: Disclosed are systems and methods for monitoring drilling fluids in real time. One method includes circulating a drilling fluid into and out of a borehole, generating a first output signal with a first optical computing device arranged near an outlet of the borehole, the first optical computing device having a first integrated computational element configured to optically interact with the drilling fluid, receiving the first output signal with a signal processor communicably coupled to the first optical computing device, determining the concentration of a gas present in the drilling fluid at the outlet of the borehole with the signal processor and generating a resulting output signal, conveying the resulting output signal to one or more peripheral devices, and adjusting one or more drilling or completion parameters in response to the concentration of the gas present in the drilling fluid.Type: GrantFiled: September 25, 2013Date of Patent: December 7, 2021Assignee: Halliburton Energy Services, Inc.Inventor: Ian David Campbell Mitchell
