20140083692 | METHOD FOR CONTROLLING FLUID INTERFACE LEVEL IN GRAVITY DRAINAGE OIL RECOVERY PROCESSES WITH CROSSFLOW - In a method for controlling interface level between a liquid inventory and an overlying steam chamber in a subterranean petroleum-bearing formation, an inflow relationship is developed to predict the vertical position in a gravity field of the interface between the two fluids (liquid and steam) with a density contrast relative to a horizontal producer well. The inflow relationship is applied to producer well completions by designing the completion to raise or lower sand face pressures according to mobility variations over the horizontal length of the well. This pressure distribution will affect liquid levels according to the inflow relationship. The completion can include tubing-conveyed or liner-conveyed flow control devices to create flow network that provides a customized sand face pressure distribution. Axial flow relationships between adjacent locations along the producer well may be modeled in order to develop an axial flow network to facilitate estimation of liquid levels at selected locations. | 03-27-2014 |
20140076538 | INNER STRING CEMENTING TOOL - A cementing adaptor includes a cylindrical carrier carrying a casing seal, a middle interval and a lower end separated by an annular rib, and a cylindrical swivel element disposed around and coaxially rotatable relative to the middle interval. A cylindrical connector has an upper end rotatably disposed around the carrier's lower end and non-rotatably connected to the swivel element, plus a lower end connectable to an inner tubular string. With the carrier's upper end connected to a casing running tool (CRT), this assembly can be disposed within a casing string with the casing seal engaging the casing and preventing fluid flow into the casing annulus below the seal when cement is pumped down the inner string, such that the cement is urged into the wellbore annulus. The swivel connection limits torque transfer that might otherwise overload the CRT or its connection to the cementing adaptor. | 03-20-2014 |
20130228343 | SHOULDER RING INSTALLATION TOOLS - A shoulder ring, for installation in a threaded pipe coupling between the installed pin ends of two pipes being connected by the coupling, has opposing end faces and a central opening, and may be lobate or circular in shape. The shoulder ring provides enhanced axial retention within the coupling by incorporating a thread element which engages the internal threads of the coupling to prevent or deter displacement of the ring from the coupling. Alternatively, enhanced axial retention may be provided by means of an interference or interlocking fit that is plastically induced during the ring installation process. The shoulder ring may be of lobate or circular configuration, with the axial retention of lobate embodiments being further enhanced by forces acting radially outward against the coupling due to elastic deformation of the ring during installation. Also disclosed are tools for installing the shoulder rings in a threaded coupling. | 09-05-2013 |

The lower-member bore has a splined upper interval, and a coaxial stinger extending upward from an annular shoulder medially located in the lower-member bore. The lower member is connected to the lower end of the housing with the stinger slidingly and sealingly disposed within the upper-member bore, and with the lower-member splines slidingly engaging the upper-member splines, thus defining upper, middle, and lower annular chambers, with the middle and lower chambers in fluid communication, and with a regulator/check valve regulating pressure in the middle and lower chambers. | 06-20-2013 |
20130000917 | CASING FILL-UP FLUID MANAGEMENT TOOL - A fluid management tool for introducing fluids into a casing string incorporates a mud saver valve configured to open and allow fluid flow in response to fluid flow pressure reaching a predetermined opening pressure, and will automatically close when fluid flow pressure is reduced to or below a predetermined closure pressure, thereby preventing fluid spillage when the tool is withdrawn from the casing. The mud saver valve includes a mud saver spool having a slotted spool cage and being axially movable within a longitudinal bore in the main body of the tool, between an upper or open position in which fluid can flow out of the spool cage and into a discharge bore at the lower end of the main body, and a lower or closed position in which the lower end is seated against the exit bore to prevent flow therethrough. A check valve may be incorporated into the lower end of the mud saver spool. The fluid management tool also may incorporate a main seal and air bleed valve subassembly and a secondary suction seal and check valve subassembly. | 01-03-2013 |
