Early (pilot) field development and production
Early (pilot) field development and production are necessary and essential preparation stages of oil, gas and gas condensate fields for rational development.
The main purposes of early (pilot) field development and production are to study identified commercial hydrocarbon deposits, to obtain data on field geology and thermodynamic parameters of reservoirs and deposits which are necessary to estimate mineral reserves, to plan the project (general or process layout) of development and accelerated preparation of a field for rational development. Another important purpose of early (pilot) field development and production stages is to increase efficiency of commercial exploration.
It is possible to recommend early (pilot) field development and production depending on the specific conditions and characteristics of deposits. Test production is applied when it is appropriate to combine purposes of deposit studies with oil, gas and condensate production on industrial scale. It should be noted that in the rational implementation of this combination provides the most complete study of geological and physical deposit parameters and evaluation of commercial hydrocarbon reserves by the method of formation pressure depletion. However, commercial oil and gas extraction from the reservoir during its test production is not always possible or rational. This is often due to the remoteness of the fields from main oil and gas pipelines, the lack or necessity for industrial oil, gas or condensate production.
Our company offers our customers a flexible approach depending on geological survey issues, availability or lack of infrastructure. Our modular solutions and technologies allow to solve the problems of any degree of complexity within the shortest possible period of time.

Smoke-free combustion of associated gas at the flare unit. Real-time metering of oil products, water and gas for each consumer (combustion, consumption, own needs). Oil, water and gas samples analysis (water cut, oil density, chloride salt weight fraction, particles content, solid particles weight content, acid content). Each well production rate individual measurement (oil, water, gas).
Well test planning using the methods of inflow performance relationship (IPR) and pressure build-up (PBU) curves. Transient well test interpretation (determination of reservoir and bottom-hole zone parameters). Previous test reinterpretation through modern software programs
Well and fluid testing
Our highly qualified personnel use the most modern and sophisticated equipment. Our specialists undergo systematic advanced training at the corporate education center. Our technological potential is backed up by more than 15 years of experience in the market with leading Russian and foreign companies. Well diagnostics quality and initial data reliability are the key to further work success.
All studies are conducted in our own accredited laboratory using world class chemical and analytical equipment. All samples pass three-step control from the wellhead to the laboratory workbench. If we are not sure about the sample quality, we do not conduct any further study to avoid misleading results for our Customers.
Oil and gas condensate testingWell testing is the main tool for obtaining information about field state at all stages of its life. For cost reduction, economic risk assessment and optimal decision-making in the process of field development within the conditions of complex fields and expensive wells operations it is important to determine hydrodynamic reservoir properties, to identify impermeable borders, to analyze the current state of reservoir and changes of reservoir properties over time, to evaluate the intervention efficiency. Our company specializes in providing comprehensive services in the testing and flowing of wells after drilling or maintenance as well as in the study of production wells. Our service package includes: planning, conducting and complete geological support of oil, gas and gas condensate well tests, sampling and laboratory studies. Well test interpretation using the methods of inflow performance relationship (IPR) and pressure build-up (PBU) curves is conducted through the use of modern software programs Saphir, PanSystem. The comprehensive analysis of well tests is conducted.
