Patent number: 10408697Abstract: Techniques for improving implementation of a downhole tool string to be deployed in a borehole formed in a sub-surface formation. In some embodiments, a design device determines a model that describes expected relationship between properties of the downhole tool string, the borehole, the sub-surface formation, and mud cake expected to be formed in the borehole; determines calibration locations along the borehole based on properties of the borehole; determines candidate spacer configurations based on contact force expected to occur at contact points between the downhole tool string and the mud cake when deployed with each of the candidate spacer configuration via the model; and determines a final spacer configuration to be used to attach one or more spacers along the downhole tool string based on expected head tension to move the downhole tool string when deployed in the borehole with each of the candidate spacer configurations via the model.Type: GrantFiled: December 28, 2016Date of Patent: September 10, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Kai Hsu, Scott C.

Patent number: 8180532Abstract: The present invention provides a leveling control system for a forestry machine (10) employing position sensors that relay information about the orientation of the carriage (12) in relation to the swing-house assembly (14) in order to control roll and pitch in a manner that maximizes the operating envelop of the leveling mechanism (38). The angles of pitch and roll of the swing-house assembly (14) in relation to the carriage (12) are measured and/or calculated and a controller (24) limits operation of the leveling mechanism (38) to an operating envelop that may be described in terms of pitch and droll. The cylinders (54, 56) are decelerated gradually as the operating envelop is approached. The controller (24) can include an automatic leveling mode. The controller (24) can change the function of the fore, aft, left and right operator controls so that they are true from the operator's frame of reference regardless of the rotary position of the cab relative to the carriage (12).Type: GrantFiled: May 23, 2007Date of Patent: May 15, 2012Assignee: Deere & CompanyInventors: James O'Halloran, Daniel Schulz
