Enhanced Oil Recovery
For Oil Sands and Downhole
Global Advanced TechnologiesSM’ LCSM is a proprietary liquid catalystSM used to extract or separate oil from formations or water without creating pollution from needing heat or pressure of other methods... Oil prices have drastically been cut, LCSM is the opportunity to continue producing oil by reducing production costs.
The proprietary liquid catalystSM, “LCSM”, extracts Bitumen from oil sands at room temperature, requires less capital infrastructure, requires less energy per barrel of oil extracted, is environmentally friendly, recyclable, and creates no pollution nor wasted water. Thus LCSM promotes the environmental and regulatory approval faster, minimizing project delays. With LCSM there is no need to build large retention settling ponds for the tailings. Thus preventing leaching into fresh water or surrounding lands...With minimal water requirement for the facility, the LCSM facility is not a burden to the city, the environment, and the local population because it does not create water shortages.
Oil sands have become one of the greatest providers of oil to the USA. “Even if only 30% of this oil could be extracted, it could supply the entire needs of North America for over 100 years. These deposits represent plentiful oil, but not cheap oil. They require advanced technology to extract the oil and transport it to oil refineries”. (Wikipedia) With the significant drop in oil prices, the revenue vs. costs using normal steam methods are not as great and producers are scrambling to find more cost effective and efficient ways to recover the stranded oil.
Steam or SAGD, (Steam Assisted Gravity Drainage) is the present standard technology for the recovery of the heavy oil from Oil sands and is creating tremendous long term environmental impacts. The recovery of the heavy oil from the oil sands is very expensive, not only monetarily but also environmentally. With the drastic reduction of oil prices, GATSM’s technology is more important than ever because both capital costs and operating costs with LCSM are significantly lower than with steam and more oil is recovered increasing revenues. In addition the sands cleaned using LCSM are ready to be replaced back into the mine location.
Global Advanced TechnologiesSM’ JV partner discovered a new molecular science that has spent years and millions of dollars in Research and Development. This new liquid catalystSM or LCSM is a proprietary formula that is also enhanced with proprietary technology to give it new molecular characteristics. At the current time, LCSM is manufactured in only one location for protection of the technology.
When LCSM is introduced to hydrocarbons (oil) in either liquid or vapor state LCSM creates a temporary molecular bond with the hydrocarbon. The LCSM /oil bond is so strong that it literally clings to itself and releases from any other surface such as formations or even water and will not re-attach until this bond is released.
LCSM is such an effective extraction process that only a few ppm or almost non detectable levels are left. LCSM also breaks water emulsions which are problems in the oil industry. When LCSM is bonded with the oil its viscosity is that of diesel for ease movement. At a set point with a small temperature increase the LCSM/oil bond is released, LCSM is recaptured for reuse, the oil is ready for processing, the soils are cleaned to ppm and ready to be returned to the environment and any water is free of oil.
LCSM does not have the environmental issues created by the present steam recovery methods. Our LCSM Modular Wash Process can recover the heavy oil at a fraction of the cost and without damaging the environment. The breakeven point for traditional steam method is $70-80/bbl. (Oil and Gas Journal) When the oil prices are low, GATSM’s liquid catalystSM SM is even more important due to its low equipment cost and low operating cost vs. steam plants that require significant energy, generate pollution and waste natural resources such as water. Our savings are $15-$20 per barrel of bitumen separated from the sands. This is a huge savings especially important with current low oil prices. Oil companies are looking for innovative technologies to lower the cost and lower the pollution. LCSM is that new innovation technology that is needed.
The overhead cost to recovery the heavy oil using standard steam method is very costly because it requires large capital cost for facilities but more importantly requires significant energy costs. The standard steam method uses 1 out of every 3 barrels of oil merely for producing steam. Steam methods currently use substantial water to release the heavy oil from the soils (twice the amount of fresh water that the entire city of Calgary uses in a year). “The extra-heavy crude oil or crude bitumen extracted from oil sands is a very viscousor semi solid form of oil that does not easily flow at normal temperatures, making it difficult to transport to market by pipeline. To flow through oil pipelines, it must either be upgraded to lighter synthetic crude oil (SCO), blended with diluents like naphtha from debit, or heated to reduce its viscosity”. (Wikipedia) LCSM does not have those issues, additionally LCSM reduces the viscosity to that of diesel for easy movement until at a set point it is recaptured for re-use.
Global Advanced TechnologiesSM’ LCSM is a revolutionary new liquid catalystSM for extraction processes that do NOT require large facilities, nor significant energy or water to separate the bitumen or heavy oil from the oil sands. Another important feature of LCSM is that it breaks water emulsions to solve problems of existing polluted leaching ponds from steam processes. Unlike present oil sands recovery technologies on the market that use steam, LCSM simply washes the heavy oil from the soils with no added heat or pressure, leaving the soils cleaned of hydrocarbons down to a few ppm. The LCSM bond to the hydrocarbon is many times stronger than any surface tension holding the bitumen to the sands and causes the oil to release from any surface including soil, sands or water and keeps it from re-attaching. Because this bond is so strong only ppm or almost non detectable levels of hydrocarbons are left in the sands or media. LCSM even breaks water emulsions which is a large problem in the oil industry.
While attached to our LCSM, the viscosity of the oil will be that of diesel for easy movement, no expensive “upgrading” is needed for transportation. This bond is strong until at a set point the LCSM /oil bond is released, LCSM is recaptured for re-use, the oil is ready for processing. The soil is clean enough to be immediately reclaimed and replaced to the mined site even by the same truck bringing the mined oil sands to the LCSM facility to secure the bitumen.

NEW Technology – “LCSM “
Traditional Technology- “Steam”
Environmental Defense just released a new report on the Alberta Oil Sands, calling it the most destructive project on Earth.
- Oil sands mining are licensed to use twice the amount of fresh water that the entire city of Calgary uses in a year. 2.5 to 10 million barrels of precious fresh water is used and rendered useless in Alberta Canada to produce the bitumen.
- At least 90% of the fresh water used in the oil sands ends up in the tailing ponds is so toxic that propane cannons are used to keep ducks from landing.
- Processing the oil sands uses enough natural gas in a day to heat 3 million homes.
- The toxic tailing ponds are considered one of the largest human-made structures in the world. The ponds span 50 square kilometers and can be seen from space.
- Producing a barrel of oil from the oil sands produces three times more greenhouse gas emissions than a barrel of conventional oil.
- Roughly 75% of the oil can be recovered from oil sands
GATSM’s LCSM Modular Wash Process is an environmentally friendly new technology and process.
- LCSM does not use water except for a vapor lock in the wash system
- LCSM uses only minimal energy to run the auger in the wash process and to raise the reclaiming tank heat a few degrees
- LCSM can clean the tailing ponds
- LCSM uses minimal energy and does not create any CO2
- LCSM recovers 99%+ of the oil
LCSM Wash System:
The oil sand is mined and transported to a crusher, where it is crushed into smaller chunks. The oil sands are then put into the LCSM Modular Wash system. LCSM replaces steam to remove the heavy bitumen. The LCSM Wash System is an enclosed system that consists of tanks with augers to move the oil sands through a bath of the LCSM and then moved to another LCSM wash unit to extract any remaining oil from the sands or soils. 99.9% of the oil is recovered leaving the soils cleaned to a few ppm or non-detectable levels.The cleaned soils are then conveyed into another tank which is heated just a few degrees to remove any remaining LCSM. The LCSM vapor is vacuumed into a chiller to re-capture the LCSM and then piped back into the LCSM Wash System for reuse. At this point the clean sands are clean enough to be put back for immediate reclamation in its original mined location as part of our enhanced oil production system for bitumen. Current reclamation has averaged more than 38 years vs. our method of sending the same mined trucks back with cleaned sands.
The LCSM encapsulated oil has the viscosity of diesel for easy flow and is pumped out of the LCSM Wash System. The LCSM encapsulated oil easily flows until a set point or location where the LCSM /oil bond can be released by adding a few degrees of temperature. The LCSM vapor is vacuumed into a chiller to reclaim the LCSM and the LCSM is taken back to the LCSM Wash System for re-use. The oil is back to its original heavy oil state and ready for processing. There is no need for expensive upgrading to move the oil.
Our facility is much less costly both in capital and operating costs than huge steam plants. Wecreate no waste water, no pollution or tailing ponds and no CO2. Our Modular Wash Systems can be relocated to be near the mining area. LCSM is not only cost effective but is safe for our environment and recaptures more oil than present technology by as much as 25%.
“New Technology” LC SM for Oil Sands SM
Traditional Technology –“Steam” for Oil Sands
(Leaving significant oil )
The crushed oil sands are mixed with hot water to form a slurry. The slurry then moves through a pipeline to the project’s extraction plant in a process known as hydro-transport (OSDC 2008e). The hydro-transport processbreaks the bonds betweenthe bitumen, water, and sand, and is sometimes enhanced with the addition of caustic soda.
The slurry enters a Primary Separation Vessel (PSV), it settles in about twenty minutes into three layers: impure bitumen froth on top, sand on the bottom, and a mixture of bitumen, sand, clay, and water (“middlings”) in the middle. The sand is pulled down from the PSV, speeding the separation, and is pumped with water into settling basins called tailings ponds. The middlings undergo secondary separation in flotation tanks. Secondary separation involves the injection of air to create additional bitumen froth, from which an additional 2 to 4% of bitumen can berecovered and redirected back to the primary system. The bitumen froth is then heated in a deaerator to remove air bubbles, and is pumped from the extraction area to the froth treatment plant (OSDC 2008e).
The bitumen froth—now consisting of bitumen, water, and solids—is diluted with naphtha and then directed through a combination of Inclined Plate Settlers (IPS) and centrifuges. These technologies separate water and solids from the bitumen using settling and centrifugal forces, leaving a clean, diluted bitumen product, nearly free from water and solids. The bitumen is then ready for upgrading into synthetic crude oil, while tailings from froth treatment are discharged to the tailings ponds after recovery of trace amounts of naphtha in a Naphtha Recovery Unit (NRU). The hot water extraction process used to isolate bitumen to this stage recovers over 75% of the bitumen in the original oil sand feed. (NOTE: GATSM’s LCSM recovers 99.9%)
LCSM’s Wash System recovers the oil from oil sands in a more efficient, cost effective and environmentally friendly way verses the Standard Steam Process. The LCSM’s Wash System allows the continuation of producing oil from oil sands even when oil prices are extremely low. This new technology is also better for the environment due to not using natural resources like water and does not produce pollutions such as air or water pollutions.
LCSM is formulated for the specific oil field. It is introduced downhole as a liquid where it turns to a vapor in order to penetrate into the pores and crevices. The LCSM encapsulates the oil so the oil literally only clings to itself and releases from any formation. The permeability allows the LCSM encapsulated oil to flow like diesel through the formation.Because LCSM is heavier and does not mix with water, the oil is released from the formations and drops to the payzone where normal water flooding pushes the oil through the payzone to the projection well.
LCSM recycles downhole to continue to bond with more oil and only works with the oil not the formation...
Unlike other chemical flooding that needs to fill the payzone and the time needed to saturate the zone, LCSM is injected as a liquid and followed by production water. Once LCSM is downhole it recycles from a liquid to a vapor to reach into the pores and crevices of the rock. LCSM immediately encapsulates the hydrocarbon so the hydrocarbon bond is many times stronger than any surface bond so the hydrocarbon releases from the formation and drops to the main channel where the LCSM is recycled back to a vapor to go back to get more hydrocarbon. The hydrocarbon’s viscosity is that of diesel for easy movement to the production well. At a set point with minimal temperature, the LCSM is distilled off ready for re-use and the hydrocarbon back to its original form.
LCSM equipment for downhole injection
2 P’s of Reservoirs:
Porosity - Oil is within pores of the rock
Permeability - Ability of the oil to flow through the rock
LCSM vapor penetrates into those hard to release locations.
The Permeability and porosity are important in downhole application as the oil is stranded in the formation. LCSM changes to a vapor to reach into the pores and crevices where it creates a temporary bond with the oil. The oil basically clings to itself and releases from the formation. Once the oil is temporarily bonded with the LCSM its viscosity is like diesel so it easily flows through the formation. This bond is easily reversed leaving the oil ready for processing and the LCSM is re-captured for re-use.
LCSM encapsulates the hydrocarbon so it immediately clings only to itself and separates from the water and other formations. The LCSM is heavier and does not mix with water. This resolves a lot of the oil production issues.

Traditional Gas Injection
- Generally the gas injected is CO2
- Low recovery rate - Successful CO2 EOR can result in approximately 15% incremental oil production
Traditional SOR- Steam Flooding
- Boilers at the surface burn oil to make steam
- Expensive - One barrel of oil burned per every three produced ¹
- With primary production, steam flooding has recovered 50-70% of oil in place ¹, less in heavy oil
With the lower cost of oil it is more important than ever to find efficient and effective ways to recover the stranded oil in down hole application. LCSM does not need steam and does not create pollutions. LCSM has the ability to reach into the pores and crevices to reach the oil and temporarily changes the viscosity to that of diesel so it can easily flow through the pay zone. LCSM creates a temporary bond with the oil which is easily released with only a few degrees of temperature increase. The LCSM is recaptured for re-use and the oil is ready for processing.
