Patent number: 10053943Abstract: An annular seal having a sealing member and method for use is provided for sealing an item of oilfield equipment. The annular seal has an inner diameter for receiving the item of oilfield equipment and a frame. The seal member is contiguous with the frame. The annular seal is configured for durability, in that it resists wear, inversion, increases lubricity, enables tightness, and/or otherwise generally increases endurance, toughness, and/or permanence.Type: GrantFiled: June 2, 2016Date of Patent: August 21, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Don M. Hannegan, James W. Chambers, Melvin T. Jacobs

Patent number: 9845653Abstract: A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs.Type: GrantFiled: April 19, 2016Date of Patent: December 19, 2017Assignee: Weatherford Technology Holdings, LLCInventors: Don M. Hannegan, Thomas F. Bailey, Melvin T. Jacobs, Nicky A. White

Patent number: 9334711Abstract: A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). A sensor measures the temperature in a cavity defined by a rotating control device “RCD” first sealing element and second sealing element, an inner member and a tubular. The RCD cavity is cooled by communicating/supplying or calculating/cooling fluid to the RCD cavity.Type: GrantFiled: January 24, 2014Date of Patent: May 10, 2016Assignee: Weatherford Technology Holdings, LLCInventors: Don M.
