Patent number: 10890175Abstract: This disclosure relates to a direct drive pumping unit having a reciprocator for reciprocating a sucker rod string and a sensor for detecting position of a polished rod. The reciprocator includes a tower for surrounding a wellhead. The polished rod is connectable to the sucker rod string and has an inner thread open to a top thereof and extends along at least most of a length thereof. A screw shaft extends into the polished rod and interacts with the inner thread. A motor is mounted to the tower, torsionally connected to the screw shaft, and operable to rotate the screw shaft relative to the polished rod.Type: GrantFiled: April 8, 2019Date of Patent: January 12, 2021Assignee: Weatherford Technology Holdings, LLCInventors: Benson Thomas, Jeffrey John Lembcke, William Kevin Hall, Clark E. Robison, Sean M. Christian

Patent number: 10400761Abstract: A long stroke pumping unit includes a tower, a counterweight assembly movable along the tower, a crown mounted atop the tower, and a drum supported by the crown and rotatable relative thereto. A belt has a first end connected to the counterweight assembly and a second end connectable to a rod string, and the belt extends over the drum. A linear electromagnetic motor is used to reciprocate the counterweight assembly along the tower. The linear electromagnetic motor includes a traveler mounted to an exterior of the counterweight assembly and a stator extending from a base of the tower to the crown and along a guide rail of the tower. The pumping unit further includes a sensor for detecting position of the counterweight assembly.Type: GrantFiled: January 29, 2016Date of Patent: September 3, 2019Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Clark E.
