Monitoring Technology provides our clients the ability to monitor their product/investments. We utilize high-speed cameras, sensors, tachometers and other sensors to predict impending failures and pinpoint root causes. Our customers are able to increase throughput, improve quality and safety, and centerline production.
REDUX Technology Overview
REDUX utilizes three new “best in class” technologies (PowerSlotting, PulseWave, EcoWash) that dramatically increase the production of existing oil and gas wells without the environmental impacts of fracking. Advantages include: Low water use, increased production, higher over-all recovery, flatter decline curves, low cost.
The PowerSlot System can be best described as part of Water Jetting Technology family. The Water Jetting Technology is not new to the oil and gas sector as the water jetting principles have been used to create all kinds of equipment and methodologies to extract more oil and gas. The claim that we have in comparison to other technologies is that it is the only machine in the market that can actually deliver on its claim of excavating rocks from the target formation and bringing this rock to the surface for examination by geologists. It is an unforgettable experience for most people to see rocks come out from the target zone as no one has ever seen rock returns from the target zone as part of the well completion process before. This enables the geologists on site to field verify that work is being done in the proper formation zone for the first time. The end result of the REDUX process is: the immediate production is higher, the decline rate is flattened and as importantly, the quantity of recoverable oil goes up. All three impact the value of the lease, which is beyond any current completion technology in the market.
Appropriate Technology Applications
Slotting is appropriate for virtually all formations except unconsolidated sands. In unconsolidated sands the technology performs remarkably well and quickly, however, post the REDUX work-over the sands tend to collapse sporadically and thus the economic profitability becomes an unknown, therefore, we cannot recommend its use at present in this type of formation. This should not, however be confused with thinly laminated sandstone/sand layers which can be brought into production where perforation could not have done so. The technology has been used in almost all the US major formations now.
At well bore depths the rocks experience an overburden pressure equal to that of a mountain thus when rocks are at a depth of 10-15,000 ft (3 – 5 km) they have imposed loads of 16,000 psi – 25,000 psi (75 – 125 MPA). Drilling a well thus can be viewed as a bit like mining and is therefore subject to the laws of Mining and Geo-mechanics. In the near-well zone as a result of the concentration of these forces the stresses increase to almost 20,000 – 30,000 psi (150-250 Mpa). The tectonic stresses operating at this level are several times higher than just the stress induced by the over-burden rock and the stresses near the well-bore zone are even higher as a result of tangential drilling stresses being added to these natural stresses.
Under the influence of high pressure the rock permeability decreases, in some cases it is close to zero. Traditional methods of opening the productive layers do not consider this complicated situation in the near well-zone and therefore they are less effective in oil/gas recovery than the REDUX system.
Porous and fractured formations are subjected to compression, that deforms the rock mass and reduces its permeability. The greater the depth, the stronger the effect can be.
Abrasive perforation slots penetrate more than 16 feet into the formation, more than sufficient to bypass the near well-bore damage and to significantly increase the well flow potential. Stress redistribution around the perforation zone and this unlocks clay and formation particles.
If our geological team determines it is desirable this method allows for 100 % coverage of the production layers, as the abrasive slotting process can be designed and performed to complete communication between the well and the production layer. Unlike some other conventional stimulation methods, slotting achieves a long-lasting effect because of its extensive surface areas.
Formations sustain two types of mechanical stress: vertical stress and horizontal stress. The act of drilling a bore-hole re-distributes mechanical stress. This is often made worse by drilling and completion damage particularly in older wells. Pay zone permeability can decrease by 5 to 10 times due to the effect of these stresses alone. (Permeability can be reduced to 10% of the natural state). Drilling and conventional completion technologies cause a high pressure low permeability area to form well-bore.
Often conventional drilling and completion technologies also damage the near well-bore zone: mechanical stress, fluid, cement, and gun debris.
- Dislodges clay particles and fines.
- REDUX slotting cuts through the compacted and low permeable near well-bore zone.
- Does not burn, scar, or “cook” the formation in carbonates.
- In sandstones reduces sand mobility problems.
- In deep gas sands, relieves overpressure damage
