“…There may be practically no infrastructure, but there is high potential for the development of the mining industry and other types of industries. The problem can be solved by developing a network of modular complexes for the production of fuels and lubricants, operating in a closed cycle system directly at the fields [23]. The production chain includes the extraction of hydrocarbon raw materials, preparation and purification of products with their subsequent use in modular thermo-catalytic cracking units for the production of arctic types of fuels and lubricants, as well as environmentally friendly utilization of gas and produced water.…”

“…As a result of deep processing of the locally produced raw materials, in this case, up to 16 tons/day of winter diesel fuel with a pour point below −35 • C, a cold filter plugging point (CFPP) below −25 • C, or up to 10 tons/day-Arctic diesel fuel (with a pour point below −55 • C, CFPP below −45 • C), as well as Euro-3 gasoline, oil, and bitumen.

To ensure year-round operation of equipment at a small field, a small installation with one set of catalytic thermal cracking, consuming up to 150 tons of raw materials (oil) per day, with a capacity of up to 50 tons of winter diesel fuel per day, will be sufficient.…”

Gas Condensate Wells: Challenges of Sampling, Testing and Production Optimization

The main problem of fluid sampling during well testing of reservoirs with near-critical fluids (gas condensate and volatile oil) is due to the fact that even a small pressure drawdown usually leads to the formation of a two-phase mixture in the bottom hole area, and it is almost impossible to take representative samples with downhole samplers or a formation tester. Sampling via test-separator and the current non-separation methods are also imperfect. An alternative method—MIKS (Multiphase IsoKinetic Sampling)—of gas condensate well testing was proposed, which is based on emulsifying a multiphase flow to particles of about 1–10 μm. Thereby MIKS would eliminate the problem of particle slippage in a homogeneous flow and enables high-quality sampling directly from the flowmeter line. The initial formation fluid is characterized by the maximum value of the condensate-gas ratio (CGR). Therefore, first, the well effluent would be adjusted to the mode with the maximum CGR using a choke manifold and a multiphase flow meter. Then the flow mixture is transferred to a by-pass line with an emulsifier to achieve an isokinetic flow. Thereafter, pressure samples can be taken into pressurized sampling bottles, in which thermodynamic conditions are preset according to the flow line. The efficiency of sampling and recombining procedures allows for conducting a study of reservoir samples in the field laboratory directly on the rig and obtaining a complete PVT report even before the completion of drilling and abandonment of the well. An additional economic effect is achieved by reducing the costs of transporting and samples storage. Well test equipment setup becomes much more compact and less weight; the costs of drilling time are reduced, which is viably important for well testing on the Arctic conditions. Another major problem in the development of gas condensate reservoirs is avoiding the condensate banking around producing wells. Optimization of condensate production can be achieved by maintaining the well operation mode at maximum CGR level by means of multiphase flowmeters. The formed condensate bank can be destroyed by a combination of methods—hydraulic fracturing, followed by cycling process—purging the formation with dried gas and/or injection of methanol into the formation. Methanol can be obtained from synthesis gas as a by-product in the utilization of associated gas also at the field. The specified set of measures will allow to revive the GC wells that are losing productivity, as well as to extend the period of high productivity of new wells.

There are many problems associated with the development of remote gas condensate fields that can be alleviated by seamlessly integrating key engineering aspects such as recovery plan, production optimization, processing, waste management, and logistics. Production optimization requires monitoring of production oil, water, and gas rates along with reservoir conditions. This can prevent economic losses by providing early detection of reservoir problems like condensate banking. Multiphase flowmeters provide compact, cost effective well testing plus real time data for improved well performance analysis. Separation, feed preparation and processing in the vicinity of production sites is performed using compact modular equipment. Catalytic desulphurization ensures high quality treatment. New atmospheric pressure catalytic treatment technologies used for gas condensate and various quality oils enable production of diesel fuel (including Arctic) and high-octane gasoline. Location of fuels and lubricants (POL) production near oil and gas production sites can solve problems associated with delivering those supplies to Northern areas, ensure efficient sales of well production, enable year-round operation of special road machinery, and reduce operating costs. A closed loop system integrating production optimization, feed preparation technologies, modular processing systems, electric power generation using gas generators, associated natural gas conversion into synthetic gas and container-based wastewater treatment plants produces a powerful synergetic effect and offers opportunities to develop hard-to-reach areas. Integrated modular production systems will help unlock Siberia’s vast natural resources both hydrocarbon and non-hydrocarbon. The potential for local energy supply may be a key economic consideration for further production of Siberia’s mineral resources.
