- Formation evaluation (~50% of content) based on data from logs, cores and WL/well tests for evaluation of lithology, reservoir quality, volume of hydrocarbons, and segmentation/barriers.
- 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.

Learning outcome

After completion of the course the student should be able to:
  • 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

Contents

Formation evaluation goes through the use of logs, cores and wireline/MWD tests for the evaluation of lithology, porosity, water saturation, permeability, HC volume, formation strength, fracture, seismic lithology and segmentation/barriers. This part of the course consists of lectures and theoretical exercises based on data from gas/oil fields in the North Sea or Haltenbanken and newly aquired cores on campus.
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.

Required prerequisite knowledge

Applicants for single subjects need to meet the requirements for admission to the master programme in Petroleum Engineering.

Exam

Written exam and assignment
Weight Duration Marks Aid
Written exam75/1004 hoursA - FValid calculator.
Compulsory computer assignments25/1004 hoursA - F
Continuous assessment. 3 written tests and 3 projects that all count equally on the grade. The projects must all be passed and an average of 40% or more must be obtained on the tests to pass the course. Students who fail one or more of the tests can take a continuation exam next semester if they have passed the projects.
