- Special Core Analysis (~20% of content) for determination of relative permeability and capillary pressure.
- Well testing (~30% of content) for analysis of test data from oil and gas wells, including data from wireline-based operations, and standard methods of practical applications of the theory to determine reservoir and well parameters from test data.
- Know the logging operations and data acquisition under/after drilling.
- Interpret relevant formation logs.
- Do a complete petrophysical field evaluation based on geology, cores, logs and tests to get the reservoir quality, fluid contacts, gas/oil volume and segmentation/barriers.
- Interpret Core Analysis tests to derive capillary pressure and relative permeability from core samples, particularly JBN, mercury and centrifuge methods.
- Apply standard methods to analyze well-test data.
- Recognize characteristics of well data that identifies well type and well effects, reservoir boundaries, distances and size of areas with and without boundaries.
- Be familiar with industry relevant software for interpretation of logs, cores or well data
SCAL consists of the use of core plug measurements to obtain relative permeability and capillary pressure. Theory and interpretation of real data will be considered.
Well testing concerns analysis of time dependent pressure data or Pressure Transient Analysis (PTA). Such data may be acquired from a variety of test methods, including Drill Stem Tests (DST) and Wire Line (WL) tests. Solutions of radial, linear and spherical diffusion equations are being used to interpret results of these tests. The analysis of both pressure drawdown and buildup data from vertical wells with and without fractures and from horizontal wells are considered. The analyses of pressure data provide information about reservoir barriers / segments, induced fracture, skin-factor and effective well radius, formation permeability, as well as reservoir limits. Applications of PTA to pressure data from Permanent Downhole Gauges (PDG) are also discussed.
