| 158 | Confined volume pressure compensation due to thermal loading | US14063084 | 2013-10-25 | US09488030B2 | 2016-11-08 | Edward T. Wood; David P. Gerrard; Joshua C. Falkner; Ramon R. Garza |
| A pressure compensation system for enclosed spaces at a subterranean location changes volume with thermally induced solubility changes of a salt in water. The salt is held in an enclosure that is either rigid, or impervious and flexible or porous and flexible. As well conditions change and temperature increases, some of the salt goes into solution with a resulting decrease in volume that compensates for thermally induced volume increase due to temperature increase in the borehole. Conversely, a decrease in borehole temperature brings some of the salt out of solution for a volume increase to offset the volume decrease of the adjacent fluid to keep the pressure stabilized in the enclosed volume. In the porous enclosure embodiment the openings are sufficiently small to retain the salt even in solution. However, minimal net flows are anticipated for pressure compensation due to changing thermal effects. | ||||||
| 159 | Hydraulic anchor for downhole packer | US14311260 | 2014-06-21 | US09482067B2 | 2016-11-01 | Colin Dewars; Philip Scott; Steven Scott |

In some embodiments, a straddle packer assembly may be held in place by the hydraulic anchor. In some embodiments, a swellable packer may be held in place during the swelling process by the hydraulic anchor. | ||||||
| 160 | SANITARY CHECK VALVE TO PREVENT WELL CONTAMINATION | US14558125 | 2014-12-02 | US20160153261A1 | 2016-06-02 | Jeremy W. Bowman |
| A sanitary check valve arranged between a drop and outlet pipes in a water well casing that will prevent operate to block a back flow of water through the drop pipe when pumping from a water source is discontinued as could contaminate that water source. The valve is for fitting into an actuator fitting body that mounts between the drop and outlet pipes opposite ends and includes a side plate for releasable coupling to a separate actuator mount that connects through the well casing and includes a drain pipe. The drop and outlet pipes fitted to the fitting body are lowered into the well casing to where the side plate edges slid between parallel sides of the mount, coupling the assembly together such that an upward water flow moves the float valve off of the drop pipe end to pass that flow through the outlet pipe for use, and, when that upward flow is stopped, the valve closes over the drop pipe end and opens to the mount drain pipe to a water flow that dumps outside the well casing. | ||||||
