Interpretation and Processing of Geophysical data

Openhole geophysical surveys:

• Radioactive methods
• Electrical and electromagnetic methods
• Sonic logging
• Inclinometry
• Profilemetry and cavernometry
• Thermometry

Geophysical surveys used to monitor field development

• Hydrodynamic studies (HPC, HL)
• Integrated equipment
• Determination of the inflow (injection) profile and watering sources

The tasks of operational control and waterflood control are:

• identification of inflow intervals, determination of operating intervals (inflow profile) and sources of flooding, inflow composition and fluid composition in the wellbore;
• allocation of absorption intervals, determination of the injectivity profile, total flow rate and production characteristics of injection wells;
• determination of the position of static and dynamic levels and Hungary, the percentage of water cut and flow rates by levels;
• the allocation of intervals annular or in-situ flows;
• determination of the hydrodynamic characteristics of perforated objects;
• determination of the hydrodynamic characteristics by the tester of pipe formations in production casing;
• determination of the technical condition of production and tubing strings;
• identification of intervals of sticking tubing string;
• determination of GOC, working and flooded thicknesses.

Monitoring the technical condition of casing strings:

• Cementing quality control
• Determination of leakages in the production string and flow intervals
• Tackler
• Tube profilometry
• Electromagnetic flaw detection and thickness measurement
• Electromagnetic coupling location

Work is underway to interpret data from past years, to refine the assessment of parameters of missed reservoirs;
Seismic data processing support - speed estimation (according to GIS data), construction of temporary travel time curves;
Scanning and digitization of logging data;
Formation of an electronic archive of GIS data and their processing results.
