BACKGROUND OF THE INVENTION

Through multiple applications, testing, research, and verification, it is found that this Process Utility Patent is specific, non-related to current technology, unique, and proven. The history of the creation of this process patent began with the small scale application for art and design purposes through the Lichtenberg wood burning application. Through further testing it was found to have the appropriate effect for application with a sedimentary and/or conglomerate rock media for the purpose of industry application.

BRIEF SUMMARY OF THE INVENTION

The completions process, or fracturing method, is intended to establish, improve, and increase connectivity between parallel wellbores. This increases permeability improves transport of in-situ fluids within the formation for means of delivery to wellbore and then surface. This process applies High Voltage electricity through means of AC, DC, or transformer regulated current from one wellbore to the parallel wellbore in order to create a network of fulgurite pathways for fluid transport.

DETAILED DESCRIPTION OF THE INVENTION

The completions process utilizes electricity to initiate and establish the connectivity from the completions application of an oil or gas well. As shown in FIG. 1, parallel wells 10a and 10b have been drilled (open not cased) into an oil and gas formation 12 within 2000′ of each other and have been made static, the process is ready setup.

A High Voltage transformer 14 and/or energy source is prepared on location for the purpose of delivering High Voltage electricity from one pole located in one wellbore 10a at specific measured depth, to the adjacent pole in the parallel wellbore 10b at the corresponding and relative measured depth. High Voltage Cable 16a or 16b, such as XLPE, PEF, PTFE, or FEP, is connected to each of the transmitting and receiving poles. Each cable 16a and 16b is then tethered and connected to a conductive device 18a and 18b pictured in FIG. 7. The cable and conductive device is attached in-line with a well tractor 20a and 20b, which is spaced 30′ behind the conductive device 18a and 18b, for the purpose of delivery down hole. Twelve feet behind the tractor 20a or 20b, a pump down pressure activated rubberized plug 22a and 22b can also be attached.

Once the conductive devices 18a and 18b are at their respective specified depths, a pump down unit (not shown) pressures up the rubberized plugs 22a and 22b, sealing the wellbores 10a and 10b in front of the plugs 22a and 22b, isolating the devices 18a and 18b. Once isolation is verified in both wellbores 10a and 10b and depth has been re-verified, the energized process may begin. FIGS. 2 and 3 depict the energized process occurring between the wellbores 10a and 10b in the formation 12.

The energy source is turned on and voltmeters are brought online for observation. The energy source is powered up and electricity is delivered downhole to begin the process. Once the electricity reaches the conductive devices 18a and 18b, connectivity begins to occur in a branch like pattern surround the wellbores 10a and 10b in a radial geometry with a tendency for reaching the opposite pole. Both electrical sources downhole are delivering high voltage through the formation 12 and conductivity is established by the in-situ connate saltwater within the formation 12. The voltage for the process can be greater than about 20 Kva in one embodiment. In another embodiment, the voltage can be greater than about 50 Kva. Once the electricity reaches each pore space, a Fulgurite formation of the sandstone or limestone will be created. The fulgurite formation establishes the connectivity and the throat space for fluid delivery from the formation 12, to the wellbores 10a and 10b, and finally to the surface. FIGS. 4 and 5 show the resulting fractures 24 in the formation 12, and FIG. 6 shows the production fluids 26 in the wellbores 10a and 10b being transported to the surface.

The process is finalized when the poles deliver successfully electricity to each other and the voltmeter verifies that connection has been made. The plugs 22a and 22b can be released, the tools are retrieved, and the process is repeated for each predetermined stage (measured depth) of the wellbores 10a and 10b for the purpose of fully executing the process of an entire wellbore completion.
