20160053565Drive Off Method from Subsea Well with Pipe Retention Capability - This invention involves a method of securing pipe (also referred to as a “string of tools”) when driving off a subsea well or sealing off a well in onshore applications where there is an emergency by grabbing the pipe before it is cut. A pipe ram then is closed on the pipe before a shear ram is actuated to cut the pipe. In subsea applications, the top of the pipe may then be raised clear of the blowout preventer within a marine riser. A blind ram and annular preventer can then be closed above the remnant of the pipe being retained by the pipe catcher. The pipe above the cut is removed through the marine riser and the marine riser itself is then disconnected. The rig is then driven off the well. If the well is reactivated the steps are reversed but the well is safely secured before the blowout preventer components are opened. The pipe supported by the catcher is independently supported before the catcher is released and the pipe lifted through the riser.02-25-2016
20160053563Support Cone for Retrievable Packer - Opposed cones for slips on a packer have an annular undercut in general alignment with the end of the cone that has the slip ramp. The undercut faces the mandrel on which the cones can be driven together to radially extend the slips. A high modulus insert sleeve is interference fitted to the undercut. This results in the cone exterior surface being in hoop stress tension before the slips are set. Once the slips are set and a reaction load comes radially back from the surrounding tubular into which the slips have extended there is a tendency for the reaction force to put the exterior surface of the cones into compressive hoop stress. The initial tensile hoop stress from the sleeve placement acts to at least in part offset the reaction force tending to create compressive hoop stress. The net loading and deflection of the mandrel is minimized.02-25-2016

Methods may include submerging the surface of the sensor plate in a downhole fluid in a borehole; activating the sensor assembly to generate a guided wave that propagates along the sensor plate, wherein propagation of the guided wave along the sensor plate is dependent upon a parameter of interest of the downhole fluid; and using information from the sensor assembly relating to the propagation of the guided wave along the sensor plate to estimate the parameter of interest. Methods may include isolating an opposing surface of the sensor plate from the downhole fluid. The guided wave may be an interface guided wave or may propagate in the plate between the surface and an opposing surface.11-12-2015
20150322770Metal Bellows Equalizer Capacity Monitoring System - A bellows position monitoring arrangement to determine the axial position of a bellows assembly within the outer housing of a seal section or equalizer. The position can be correlated to an amount of motor oil being retained within the bellows assembly.11-12-2015
