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.

Patent number: 9175542Abstract: Sealing elements have lubricating seal profiles for communicating fluid between the sealing elements and the sealed drill string tubular or other oilfield component while the sealed drill string tubular or other oilfield component rotates or moves vertically relative to the seal elements. The same fluid used for drilling may also be used for seal lubrication, such as water, drilling fluid or mud, well bore fluid or other liquid or gas. The sealing elements may be disposed with a seal housing, which may be positioned with a marine riser, or subsea without a marine riser. The seal housing may prevent rotation of the seal elements with the sealed drill string tubular or other oilfield component. Alternatively, the seal housing may be an RCD that allows the sealing elements to rotate.Type: GrantFiled: June 28, 2010Date of Patent: November 3, 2015Inventors: Thomas F.

Publication number: 20150034326Abstract: A system compensates for heave induced pressure fluctuations on a floating rig when a drill string or tubular is lifted off bottom and suspended on the rig, such as when tubular connections are made during MPD, tripping, or when a kick is circulated out during conventional drilling. In one embodiment, a liquid and a gas interface moves along a flow line between a riser and a gas accumulator as the tubular moves up and down. In another embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. In other embodiments, a piston connected with the rig or the riser telescoping joint moves in a fluid container thereby communicating a required amount of the fluid either into or out of the riser annulus.Type: ApplicationFiled: October 17, 2014Publication date: February 5, 2015Applicant: Weatherford/Lamb, Inc.Inventors: Don M.
