Patent number: 10801921Abstract: Systems and methods for improving fuel economy in vehicles such as Class 8 trucks are provided. In some embodiments, signals indicating states of the powertrain are collected and used to generate fuel rate optimization values. Fuel rate optimization values may indicate a difference between optimum fuel flow rates and actual fuel flow rates during a vehicle drive cycle. Recorded fuel rate optimization values may be used to compare different vehicle configurations during testing, and may also be used to evaluate vehicle performance during real-world operation.Type: GrantFiled: September 16, 2019Date of Patent: October 13, 2020Assignee: PACCAR INCInventors: Christopher Michael James Douglas, Michael Douglas Gerty, Mark G. Malowicki

Patent number: 10385686Abstract: A method for determining a hydrocarbon-bearing reservoir quality prior to a hydraulic fracture treatment based on completions index is disclosed. The method comprises a step performing a test determining a hydraulic pressure at which a hydrocarbon-bearing reservoir will begin to fracture by pumping a fluid in a wellbore, wherein the wellbore extends from a surface to the reservoir and the wellbore has one or more perforations in communication with reservoir; a step generating a pressure transient in the wellbore, the pressure transient travels from the surface to the reservoir through the perforations and reflects back the surface after contacting the reservoir; a step measuring response of the pressure transient at sufficiently high sampling frequency; a step determining fracture hydraulic parameters of the perforations and the reservoir using the measured response; and optimizing a stimulation treatment to the reservoir based on the determined fracture hydraulic parameters.Type: GrantFiled: October 28, 2014Date of Patent: August 20, 2019Assignee: EOG RESOURCES, INC.Inventors: Christopher Michael James, Oscar A. Bustos, Evan Daniel Gilmore, Eric Robert Matus
