Abstract: A method for a pulsed gamma - gamma density tool to simultaneously compensate for interactions due to the photoelectric effect and density variations caused by standoff enables a more precise determination of bulk formation density. This method includes the steps of providing a source of energetic particles and directing those energetic particles at a formation having a known photoelectric factor and electron density and capturing one or more photons either emitted or deflected from the formation either a first detector or a second detector. The first detector is spaced a first distance from the source, the second detector is spaced a second distance from the detector and a third distance separates the first detector from the second detector. Measuring a first total energy of the photons striking the first detector during a time interval and measuring a second total energy of the photons striking the second detector as a function of the time interval and disposing a first filter between the first detector and the formation effective to cause Pe response to match standoff influence thereby compensating for both effects simultaneously. In addition to the first filter, the required compensation may include a second filter between the second detector and the formation as well as adjustments to the respective first distance, second distance and third distance.

Abstract: A vertically adjustable mechanical bed consisting of a bed frame for support of a mattress and occupant attached to moveable leg means powered by a motor means. Operation of the motor means causes a bearing block attached to ft leg means to move longitudinally along a guide rod means, thereby collapsing the leg means beneath the bed and moving the bed frame vertically. Collapsing the bed to its substantially lowermost position causes the bearing block to engage a spring, thereby compressing said spring between the bearing block and a transverse member of the bed frame. The energy stored by the compression of the spring is used to raise the bed from its substantially lowermost position. Pivotally attached to the leg means is a rolling means consisting of a caster and foot arrangement. During normal operation, the foot is firmly engaged with the floor surface. When the bed frame moves to its substantially uppermost position, a pin extending from the leg means and constrained in a slot on a flanged face of the rolling means engages one end of the slot, thereby causing the rolling means to pivot and the caster to engage the floor, rendering the bed horizontally mobile.

Abstract: An ESP variable speed drive controller functions in conjunction with a safety logic solver, dedicated pressure sensors and a surface emergency isolation valve, or safety shut-off valve (SSV), to perform a full functional test of the complete wellhead flowline system. The method includes the step of using a plurality of pressure transmitters to monitor the flowline pressure during normal operations and during a full stroke test of the safety shutoff valve and adjusting the speed of the downhole ESP during the test to maintain the pipeline pressure within predetermined safe pressure limits.  This wellhead flowline protection system and method utilizes the downhole ESP speed controller and an SSV to ensure that dangerous pressure levels are not reached and provides for full functional safety testing of the wellhead system. The ESP motor speed controller is used to permit functional testing and remove the pressure source from protected downstream flowline piping.
