20090032237 | Shape Memory Alloy Closure Spring for Subsurface Safety Valves Triggered by Well Fluids - A shape memory material is used for a power spring in a subsurface safety valve. The spring is sized for the force it will deliver when it goes past its transition temperature and reverts to an original shape. The force released by having the spring pass its transition temperature holds the valve closed against hydrostatic pressure. Since the force exerted by the spring does not increase as the valve opens less force is required to hold the valve in the open position, thus lowering opening pressure. The trigger to cross the transition temperature comes from the expected temperature of well fluids at the mounting position of the subsurface safety valve. Other downhole applications are anticipated. | 02-05-2009 |

20140332199 | Tunable Down-Hole Stimulation System - Tunable down-hole stimulation systems feature closed-loop control of pumps and tunable down-hole stimulators. Stimulators generate and hydraulically transmit broad vibration spectra tuned for resonance excitation and fracturing of geologic materials adjacent to the wellbore. Feedback data for controlling stimulation includes backscatter vibration originating in stimulated geologic material and detected at the stimulator(s). For initial fracturing with relatively large particle sizes, the power spectral density (PSD) of each stimulator output is down-shifted toward the lower resonant frequencies of large particles. As fracturing proceeds to smaller (proppant-sized) fragments having higher resonant frequencies, backscatter vibration guides progressive up-shifting of stimulator PSD to higher vibration frequencies. Stimulator power requirements are minimized by concentrating vibration energy efficiently in frequency bands to which geologic materials are most sensitive at every stage of stimulation. Geologic fragmentation efficiency is thus optimized, with inherent potential for plain-water fracs completed with self-generated proppant. | 11-13-2014 |

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.

20160186543 | SYSTEM FOR CHEMICAL TREATMENT OF A SUBSURFACE WELLBORE - A well chemical treatment system includes a chemical dispenser having a control signal input and a chemical outlet in fluid communication with a well. A chemical dispenser controller operates the dispenser and detects a well fluid lift pump controller signal. The chemical dispenser controller transmits a control signal to the chemical dispenser at selected times and is configured to increment the counter and inhibit transmission of the control signal when a selected time occurs and a pump in operation signal is not detected. When the chemical dispenser controller detects a pump in operation signal at one of the selected times, the chemical dispenser controller sends a control signal to the chemical dispenser to dispense an amount of chemical into the well equal to a product of a number in the counter plus one and an amount of chemical to be dispensed into the well at each selected time. | 06-30-2016 |
