Selection of chemical reagents based on geological and technical conditions well test facilities
Geological exploration work
Nekko LLC can act as a single contractor for the entire range of geological work performed for the purpose of search, discovery and preparation for the development of hydrocarbon deposits, and as a result, the Customer gets one responsible for the entire range of work, as well as the development of a unified work plan
Acid treatment of bottomhole formation zone
Inflow call
Well development, well cleaning, well output
• Application of innovative equipment designed and manufactured in-house;
• Putting the well into flowing mode using a PULSE jet pump with subsequent development of the well without additional downhole operation (through the jet pump casing);
• Round-the-clock control of the well development process.
Gas-dynamic surveys of wells / Gas-condensate surveys of wells
• Method of steady-state selections;
• Method of unsteady selections of gas-condensate well surveys.
Deep and surface sampling, operational analysis of samples
• Conducting a full range of tests of deep and surface samples in accredited laboratories. Multi-level control of the process of sampling and delivery of samples to the laboratory;
• Sampler with gas sampling capability under formation conditions;
• Wellhead samples. Control of well cleaning after bottomhole zone treatment, operational analysis of water samples for chlorine ions, acidity;
• Separator samples. Sampling of conditioned samples in special samplers PGO (100, 400, 10 000);
• Deep samples. Sampling of deep samples of formation fluid using “SIMSP20” geophysical sampler of “VMK” modification;
• Evaluation of the quality of sampling.
Laboratory analysis of depth and surface samples in an accredited laboratory
Laboratory chemical analysis of gas, condensate and water is performed in a certified laboratory in accordance with approved and recommended industry standards, instructions and methods.
During laboratory chemical-analytical studies of gas and liquids sampled from the separation unit, the following parameters are determined:
• Physical and chemical characteristics of formation gas and stable condensate (under standard conditions);
• Component composition of condensate, separation and degassing gas and formation gas;
• Chemical analysis of formation water sample composition.
Interpretation based on test results
• Determination of the inflow profile, taking into account reservoirs;
• Calculation of associated gas flow rate by modes;
• Summary table of the study results;
• Indicator diagram of the test interval;
• Determination of formation hydrodynamic characteristics by pressure recovery method;
• Processing of the pressure recovery curve by nonlinear regression on the diagnostic graph;
• Operational analysis of fluid samples.
Conclusion of the test results
• Composition of products;
• Mining capability of the facility;
• Filtration and capacitance parameters;
• Hydrodynamic characteristics of the formation;
• Physical properties of fluids;
• Chronology of the tests;
• Data from deep autonomous instruments;
• Materials of geophysical surveys;
• Formation and bottom hole parameters.
