Stimulation Services Provided:
Blue Water Petroleum will seek to joint venture with under capitalized oil producers to stimulate their wells and increase production by use of acidizing, nano-engineered solvents and custom engineered surfactants to maximize production from older existing wells.
Acidizing & Chemicals
Today, acidizing is one of the most widely used and effective means available to oil and gas operators for improving productivity (stimulation) of wells. Acidizing is commonly performed on new wells to maximize their initial productivity and on aging wells to restore productivity and maximize the recovery of the energy resources.
ECT - Exo-Thermic Chemical Treatment
Technology of oil and bitumen output stimulation by heat and increase in bottom hole pressure from exothermic reactions of chemical mixtures in a downhole gas generating system (ECT- Technology).
Microwave Crude Oil Production
Microwave technology is used for the extraction of oil shale, which is different from shale oil. Oil shale is found in rock formations that contain kerogen. One of the current extraction methods of kerogen has been strip mining because these are shallow formations. The extracted rock is then crushed and heated to high temperatures to liquefy the oil.
Microwave Heavy Crude Upgrading
The use of microwave heating technique has shown tremendous research interest and potentials. As demand from oil is increasing worldwide, heavy crude oil are often priced at a discount to lighter ones due to low proportion of low- boiling constituents (light fractions) and high concentration of impurities which create many operational and quality problems.
Microwaving Usefd Tires to TDF's (Tire Derived Fuels)
Tire-derived fuel (TDF) is composed of shredded scrap tires, tires may be mixed with coal or other fuels, such as wood or chemical wastes, to be burned in concrete kilns, power plants, or paper mills.
Ultrasonic Well Treatment
Paraffin, asphaltenes, particles and other substances are blocking pore spaces. The oil well is not producing at its optimal capacity so the high power ultrasound breaks the adhesive forces that hold the blockages in place so that they are removed.
Undeveloped Heavy Oil & Bitumen Reserves
According to the USGS, there are hundreds of billions of barrels of proven heavy oil and natural bitumen reserves globally that are not being produced due to technical and economic viability reasons. Heavy oil is crude with an API gravity between 10-20. Natural bitumen has an API gravity normally between 4-9. In the past, steam technology was used to produce heavy oil (Athabasca, Bakersfield) but often the cost of production has exceeded $50/bbl making steam not viable in the current price environment. The other problem with the steam method is that the produced heavy oil will solidify quickly as it cools necessitating the addition of costly viscosity reducers known as diluents or heated tanks to maintain the temperature until delivery to the refinery.
Mature Oil Fields & Future Production Potential
The typical oil well only produces 30-50% of its reserves before it declines and gets plugged and abandoned. This is because the natural Bottom Hole Pressure that is helping to force the oil out becomes depleted or exhausted. Good wells can often become ‘strippers’ (making less than 10 BOPD) very quickly because the natural gas pressure in the formation declines as the oil is produced leaving only the pressure created by the overburden rock. The oil production itself leaves deposits of paraffin, asphalt, iron and scale that plug off the original porosity and permeability of the reservoir that also diminishes production with time. This means there is much more oil left behind in most wells than has ever been produced. This oil can now be recovered.
Acid Treatment of Old Wells
Oil wells can be treated with Hydrochloric Acid (HCl) with a variety of other chemicals to specifically clean wells of production robbing contaminants that plugging of the perforations in the casing and the inter-granular porosity and permeability of the oil producing formation. The acid dissolves contaminants such as calcium scale. Added nano-solvents that are added to the acid will dissolve ashaltines and paraffins to re-open natural channels in the rock while the acid can create new channels and enlarge old ones by dissolving the calcite that often binds sand grains together. Other components in the solution then ‘plate’ the clean surfaces creating a ‘teflon’ effect that retards the re-accumulation of the contaminants that reduce production. Acidizing is a fast, cheap and effective stimulation treatment that yields immediate results.
Acid Treatment of New Wells
New wells can be treated with acid to clean fresh perforations that may be ‘skinned over’. Skinning over is caused by the perforating bullets leaving a smooth impervious surface on the interior wall of the perforations. The acid will dissolve the smooth surface and re-open the natural porosity, and it can also help extend the existing natural channels to help increase the initial production (IP) of the well.
Hot Gas – Exo-Thermic Chemical Treatment (ECT)
Old wells can be rejuvenated with ECT and heavy oil/bitumen/tar sands can be produced with the same method. When an older well or field has exhausted its natural pressure (BHP) it can be recharged with the injection of hot gas into the formation. The hot gas is created downhole when several chemicals are mixed adjacent to the perforations. A packer placed above the perforations contains the reaction and directs the hot gas into the oil bearing pay zone. The hot gas can be as high as 500 degrees F and applied with 1,000 PSI or more. This treatment can create significant production for a year or more in a previously non-producing well. Individual wells can be treated in a huff-n-puff manner, or an entire field can be treated from a central injection well. The ECT technology can open the way to producing the billions of barrels of ‘heavy’ oil and residual oil in old exhausted fields.
When microwaves are applied to crude oil at a certain wavelength and frequency it breaks the molecular hydrocarbon chains into shorter lengths. The heavier the oil is the longer its molecular chain is, so by breaking the chain into shorter links it causes the following effects:
- Heavy oil and bitumen becomes lighter due to the shorter chain, and the change is permanent.
- The API gravity and viscosity is vastly improved, and increases the value of the oil.
- Heavy oil and bitumen can now flow out of the well. The oil will not solidify again after cooling (as with the steam production method)
- Conventional oil in tanks can be microwaved and upgraded so that it commands a better price at the refinery. The microwaves also separate the oil from water, Sulphur, asphalt and other contaminants that settle to the tank bottom. This also adds significant value to the crude.
- The microwaves can be delivered downhole and applied to the oil bearing formation or surface tar sands to liquefy and produce the immobile oil.
- Microwave antennas can be installed into storage tanks and tank batteries to continuously upgrade crude oil of any API gravity and quality.
- Below are the results of a microwave treatment of a 12 API gravity crude that was upgraded to 25 API gravity adding $10/bbl to the value of the crude.
