20150376995 | MODULAR TOP LOADING DOWNHOLE PUMP WITH SEALABLE EXIT VALVE and VALVE ROD FORMING APERTURE - A method and apparatus for improving the production efficiency of a well and preventing gas lock. The apparatus is a downhole pump and comprises a barrel, a reciprocating plunger and a body having a plurality of inlet valves. The apparatus does not require outlet valves. The body and inlet valves are positioned above the barrel and plunger, thus eliminating gas lock. Fluids enter the body through the valves and, during upstrokes of the plunger, are forced up the tubing string to the surface equipment. Modularity of the components permits pump components to be changed as the productivity of the well fluctuates and also allows production of more fluids with a smaller casing. The invention prevents gas lock by permitting gasses to escape between a sliding valve and a valve rod connected to the plunger. Additionally, an exit valve sealably engages the valve rod, which forms an aperture. During operation of the pump, the gasses escape through the aperture in the valve rod and rise up the tubing string. | 2015-12-31 |

On the upstroke, the chamber valve is dragged closed for sealably retaining the compressed gassy fluid therein while drawing an additional increment of fluid through the standing valve into the pump chamber. Continued downstroke and upstroke cycles increases pressure of the compressed gassy fluid in the pump chamber until it exceeds the hydrostatic head above the travelling valve for resumption of normal fluid pumping. | 2015-12-31 |

The non-halogenated molecules may be combined with substrates and introduced into a subterranean location, desorbed and recovered from the subterranean location with a fluid, reacted with a reagent (e.g. pentafluoro benzyl chloride) to give a derivatized tracer. Alternatively, the tracer molecule release can be delayed by use of an emulsion or a coating that allows slower diffusion of the tracer into the fluid. The presence of the derivatized tracer is then detected in the recovered fluid. A different non-halogenated tracer may be used for each hydraulic fracturing stage, e.g. to determine from which fracturing stage water is produced and from which oil is produced. | 2015-12-31 |

It can also supply gas to run the system, or generate electricity or various other auxiliary functions.

One well at a time, or entire fields can be produced with a single compressor. Stripper wells account for 40% of total domestic production. There are 1000s of wells not being produced. Huge production OPEC type wells could be produced with this system better, faster, and less expensive than any other system. This is also environmentally cleaner as very little gas will escape to the atmosphere.

The device may also include an interconnection arrangement configured to couple the RF source and the first and second terminals so that at least one of the upper and lower wellbore RF radiators heat the hydrocarbon resource in the subterranean formation. | 2015-12-31 |

20150377003 | SYSTEM AND METHOD FOR SURFACE STEERABLE DRILLING TO PROVIDE FORMATION MECHANICAL ANALYSIS - A method for determining geological formation characteristics involves driving a bottom hole assembly (BHA) in a borehole. At least one mechanical drilling parameter generated is detected responsive to operation of the BHA in the borehole. At least one geological formation characteristic is identified responsive to the detected at least one mechanical drilling parameter. The identified at least one geological formation characteristic is provided to a surface steerable drilling system. Operation of the surface steerable drilling system is controlled responsive to the at least one geological formation characteristic. | 2015-12-31 |
20150377004 | Closed Loop Control of Drilling Toolface - A downhole closed loop method for controlling a drilling toolface includes measuring first and second attitudes of the subterranean borehole at corresponding first and second upper and lower survey stations. The first and second attitudes are processed downhole while drilling to compute an angle change of the subterranean borehole between the upper and lower survey stations. The computed angle change is compared with a predetermined threshold. This process may be continuously repeated while the angle change is less than the threshold. The first and second attitudes are further processed downhole to compute a toolface angle when the angle change of the subterranean borehole is greater than or equal to the threshold. The toolface angle may then be further processed to control a direction of drilling of the subterranean borehole. | 2015-12-31 |
