Definitions
- Our invention lies in the field of the recovery of crude oil and other hydrocarbons from an underground reservoir of crude oil by means of an oil well.
- the invention is applicable to those underground hydrocarbon reservoirs which contain undesirable crude oil-water emulsions and entrained gases and those wells having deposited scale and corrosion problems.
- the first ingredient is negatively charged water, preferably water which has been treated, that is, pumped through, a device which we have invented and named the Ion ColliderTM which alters some of the physical characteristics of its treated liquids.
- Ion ColliderTM treated water has a number of altered characteristics including the fact that it is negatively charged.
- particles of a unique metal alloy about the size of coarse silicon sand particles are injected into the stream of preferably Ion ColliderTM treated water and the water flow rate maintained sufficiently high to deposit the metal alloy particles throughout the reservoir.
- the alloy is preferably 90% copper, 5% nickel and 5% zinc.
- Other chemicals may or may not be added to the stream of water to reduce friction pressure and help carry the alloy particles in the fluid stream. As the particles of alloy are pumped out of the well and into the reservoir, they react with the reservoir rock, freeing entrained gases and breaking up oil-water emulsions encountered along the pumped path of the alloy particles.
- frac sand When the alloy particles have permeated the reservoir, frac sand may be added to the stream of pumped Ion ColliderTM treated water in order to prop-up and hold the formation open providing a path of least resistance for fluid flow from the reservoir, thereby insuring a continuous flow of hydrocarbons to the wellbore.
- the volume of frac sand if any is used, depends upon the reservoir size and its characteristics and its history of prior reservoir stimulation. If frac sand is utilized, as soon as the predetermined volume of frac sand has penetrated the reservoir, a sufficient volume of negatively charged water is pumped in to flush all the frac sand out of the well casing and away from the wellbore.
- the well is then shut-in to allow the alloy particles and any frac sand to settle and stabilize in their positions within the reservoir.
- the shut-in period varies wid the particular reservoir being treated and lasts from as little as thirty minutes to a maximum of twenty four hours.
- Fig. 1 is a flow chart showing the basic steps of our process
- Fig. 2 is a flow chart showing the steps of our process when frac sand is included in the process.
- Fig. 1 sets forth the basic steps of our process. However, based upon our review of die geology and history of all ten abandoned wells, on several wells we decided to add frac sand and Fig. 2 sets forth the steps used in treating these wells.
- Ion ColliderTM is very effective in negatively charging water, other means of producing the negatively charged water may be used.
- Ion ColliderTM treated water was pumped down the well casing, through the wellbore and into the formation at 1200 p.s.i. (8273 kPa).
- the formation pressure then broke to 500 p.s.i. (3447 kPa) at which point we added 50 pounds (22.7 kg) of our copper-nickel-zinc alloy particles to the stream of negatively charged water until all the alloy particles had been flushed out of the casing and into the reservoir.
- a total of 40 barrels of negatively charged water was pumped down the well.
- the well was then shut-in for two hours with a shut-in pressure of 200 p.s.i. (1379 kPa) at the surface of the well.
- a workover rig was then used to swab the well casing and a total of
- Heilman #7 was treated on February 25, 1995. A total of 230 barrels of Ion ColliderTM treated water was pumped down the 2 7/8 inch (7.30 cm) casing of Heilman #7 at a rate of 10 barrels per minute.
