Oil and Gas Recovery ToolOil recovery tools that help extract more oil from existing production wells.
Overview
Seismic wave stimulation technology provides the solution for extracting the huge amounts of oil left behind in reservoirs.
There have been numerous methods and processes for oil recovery in an attempt to find a technique for removal of immovable-unswept oil in depleted oil fields. As yet no technology has effectively solved the problem. A significant volume of oil is by-passed because of injected waterbreak through bottom water coning; reservoir heterogeneity or vertical heterogeneity in multi layered reservoirs. This oil is not produced and remains in the reservoir due to the depletion of energy in saturated reservoirs.
The seismic wave stimulation technology introduces special vibrations into the formation, which effects the fluids and gases in the reservoir. It decreases the cohesive and adhesive bonding, as well as a significant part of the capillary forces, thus allowing the hydrocarbons to flow more easily within the formation.
The vibrations that propagate into the reservoir as elastic waves change the contact angle between the rock formation and the fluids, reducing the hydraulic coefficient of friction. This allows a freer flow toward the wells, where velocity increases and creates a greater pressure drop around the well bore. The elastic waves give rise to an oscillating force in the strata, that results in different accelerations because of different fluid densities. The fluids will "excite" each other due to different accelerations and create frictional heat, that, in turn, reduces their surface tensions. The elastic waves will also release trapped gas, contributing to a substantial gas lift of the oil.
Basically stated the invention creates an elastic wave flood in the formation, covering approximately one and one-half square miles per elastic wave stimulation.
Implementation and use of the seismic wave stimulation technology is environmentally safe. It requires no chemicals or other environmentally harmful materials; it causes no damage to the formation, wells, or any of the equipment. The elastic wave oscillations emitted by the wave stimulation technology create a uniform disbursement of the trapped reserves. Once released the reserve is driven by pull force of the well.
Government funding is available for DOE Testing. DOE testing on this technology/Tool has been approved.

Primary Application of the Technology
Oil increase, decline decrease in existing Marginal/Stripper Wells. Oil Producers, oil fields, wells needing enhancement. diversifies oil enhancement
A stripper well or marginal well has been understood to be an oil or gas well that is nearing the end of its economically useful life. "Stripper well" or "marginal well" are terms generally used to describe wells that produce natural gas or oil at very low rates—less than 10 barrels per day.
With the price of crude oil spiraling upward and the peak oil apex imminent, an interest in reclaiming untapped reserves in these stripper wells is becoming a topic of renewed interest.
In the United States of America, one out of every six barrels of crude oil produced comes from a marginal oil well, and over 78 percent of the total number of U.S. oil wells are now classified as such. There are over 400,000 of these wells in the United States, and together they produce nearly 900 thousand barrels of oil per day, 15 percent of U.S. production.
