Carson aerogravity provides Geophysical survey, processing and interpretation of data for oil and mining exploration by specially designed helicopters and boats for aerogravity and aeromagnetic surveys. Sikorsky S-61 and DeHavilland Twin Otter are two specially designed helicopters for aerogravity surveys. Output of all systems employed in airborne surveying (gravity meter, magnetometer, positioning system, altimeters) are recorded digitally and unfiltered on the aircraft for computer processing using Carson's own processing and mapping software.
Carson builds, modifies, and maintains its own LaCoste & Romberg dynamic gravity meters at its Gravity Meter Company in Austin, Texas; many patented innovations are found on Carson's meters including the only 3-axis dynamic stabilization system for airborne surveys; a complete gravity meter testing laboratory physically tests new ideas
Carson's Experience
Carson, as the pioneer and market leader in the field, has flown over 1 million line kms survey flight in about 60 basins for over 90 oil exploration agencies in the past two and a half decades.
In Asia, Carson has carried out surveys in Turkey, Pakistan, Myanmar, Malaysia and Indonesia, all in the immediate neighborhood of India, besides a host of countries in Africa and South and North Americas. Carson along with a few major oil companies maintains the ground test strip for validating the aerogravity data as and when required.
NESCOS AS (formerly Triangle Equipment AS) is a provider of advanced downhole well completion equipment to the international oil and gas industry.
Nescos’s two main products are the MRS flow control sleeve and the NESCOS smart well system.
Mechanical Rotation Sleeve (MRS)
The "MRS" (Mechanical Rotation Sleeve) is a multi-position flow control sleeve operated by a shifting tool with a sleeve position read-out.
The MRS system is suitable for water shut-off, coning control, flood front control, injection and production rate control, production of various GOR/GWR zones etc., with its adjustable opening, and is, therefore superior to on/off sleeves.
The MRS choke valve is operated by either coiled tubing, wireline tractor or slickline shifting tool and provides sensor feed-back on sleeve position
Smart well Completion system
NESCOS is an all-hydraulic smart well completion system for flow control in hydrocarbon producing and water injection wells. NESCOS has several innovative features, such as rotation sleeve, metal-to-metal sealing and multi-position choke.
The NESCOS (Non Electric Surface Controlled System) smart well valve is operated hydraulically from the surface.
The NESCOS valve is used for optimizing oil and gas recovery, by selectively controlling production and injection.
NESCOS is a sophisticated production tool with multi-position regulation and tailor-made choke.
NESCOS has several innovative features, such as rotation sleeve, metal-to-metal sealing and hydraulic position feed-back.

ALCO Gas & Oil Production Equipment Ltd. was incorporated in 1972, as closely held, privately owned Canadian corporation to supply production and processing equipment to the Canadian and international Oil and Gas industry. During the past 34 years, ALCO Gas & Oil has designed and fabricated over 6,000 production and process packages.
ALCO specializes in packaged equipment, ranging from single skid units to interconnected multiple skid modules for larger gas processing plants and petrochemical systems
The main products include:
LPG Extraction Plants/Hydrocarbon Dew Point Control Units (5-65 MMSCFD)
These plants are used to remove Liquefied Petroleum Gas (L.P.G.) from the gas stream and extract a C3+ or C5+ (e.g. 12# RVP) The C3+ product can be further fractionated to produce C3+, C4+ and C5+ products.
AlCO Gas & Oil has fabricated more than 200 units worldwide The alternatives for removing the L.P.G. vary from relatively simple Joule Thompson (J.T.) or choke plants, through refrigeration plants to highly sophisticated packages (such as lean oil absorption or turbo expander processes), recovering in excess of 90% of the propane plus components. ALCO Gas & Oil can recommend an optimum design based on capital cost, operating costs and the time value of money. All of these processes would include dehydration of the gas stream (and in some instances the liquid hydrocarbon streams).
Amine/Gas Sweetening Plants (5-65 MMSCFD)
Amine/Gas Sweetening Plants are used to remove acid gas (H2S and CO2) in the well effluent prior to use. Alco can custom design a plant utilizing the amine that best suits your process conditions. ALCO Gas & Oil has extensive experience with MEA, DEA, DGA and MDEA (and MDEA based proprietary amines).
The plants can be custom designed and the alternatives for removing the acid gas vary from relatively simple MEA and DEA plants to the more sophisticated, selective solvents such as MDEA (and MDEA based propitiatory amines).
Gas Dehydration Packages (TEG/MEG) upto 125 MMSCFD
ALCO Gas & Oil's custom designed glycol dehydration package offers a speedy economical solution for removal of water vapour from your gas stream. Removal of the water prevents hydrate formation, corrosion and maximizes pipeline efficiency. There are well over 2000 glycol dehydration packages designed and fabricated by ALCO Gas & Oil Production Equipment Ltd. in service at this time.
The plants can be custom designed to meet your specific needs with options to increase efficiency, reduce space requirements, etc. The alternative methods of gas dehydration include desiccant and calcium chloride packages.

The benefits of subsea applications are:-
Thermtech is a Norwegian company and the owner and supplier of the Thermomechanical Cutting Cleaner (TCC) technology, a patented and advanced thermal desorption technology able to treat various kinds of oily sludge. Thermtech uses TCC for treatment of Oil drilling waste. TCC cleans the waste using evaporation to separate fluids from the cutting, a thermal desorption technology different from conventional systems, which transfer heat indirectly from large surfaces that are heated by steam, hot oil or heat tracing.
In TCC, the waste is heated by transforming kinetic energy to heat by friction. The highly efficient TCC evaporates water and oil in a fraction of exposure time required in indirect dryers, minimizing thermal degradation of the base oil, thus enabling this valuable product to be reused. Dry solid discharged from TCC has <200 ppm oil content, recovered oil has <1% water content and recovered water has <100 ppm oil content. It is the Best Available Technique (BAT) for drill-cutting treatment. TCC is a safe, compact, reliable, environment-friendly, easy to re-locate and hassle-free thermal desorption technology.
As a consequence of the small footprint and the inherent safety, the TCC is probably the only thermal technology that can be operated on board a drilling rig. Thus, the base oil can be recovered for re-use at rig site. TCC’s capacity is dependent upon the amount of water in the waste e.g. a “3 ton per hour” unit will have that capacity with solids/water/oil ratio of 70/15/15 (by weight) and will have a main motor/engine of approximately 700kW. If the water content is lower, the capacity of the same unit will be higher than three tons per hour.
