Petrophysics

Issues to solve by petrophysical interpretation:

Lithology differentiation
Stratigraphy well-to-well correlation
Pay zones identification
Determine fluid types and reservoir quality discrimination
Determination of porosity, permeability, saturation, fluid contacts, net pay zones.

Our service help You to achieve

Cumulative production growth

due to well placement in the reservoir with the best reservoir properties

Oil recovery factor increase

due to minimization and control of water cone formation

Reduced costs for LWD devices

due to the ability to interact with any manufacturers of devices

Reduced well construction costs

by optimizing core testing programs and the required logging complex

Construction time reduction

due to the efficiency of final reports and decision-making preparation

Petrophysics services include:

1. Analysis of the current petrophysical model, if any.

2. Logging data audit.

Actual scope of work
Log quality control, data inventory, depth shifting, harmonization.
Audit conclusion, capability assessment to build correlation between core and log data, formation evaluation.

3. Core data analysis

Core measurement summary
Depth shifting core to log data
Analysis petrophysical parameters received in the process of core data audited entity control and check, included mineralogical analysis, porosity and permeability correlations, electrical and sonic properties etc. Result mostly depended on core measurement summary.
Lithology interpretation based on comparing log and core data.
Estimate porosity, permeability, and saturation cutoff values
Build correlations between core-core and core-log data. Correlations included facies and textural analysis, rock types and pore structure.

4. Petrophysical integrated interpretation of core and production data. Shared petrophysical model based on core and log data. Expansion of interpretation model to standard logs.

5. Integrated verification analysis of convergence results by core, flow and log data.
