Reservoir Evaluation Technology (GEO504)

Petrophysical evaluation and interpretation of geological formations are done to understand the storage capacity, fluid flow and reservoir characteristics required for hydrocarbon reserves estimation and implementation of production strategies. This evaluation is done by running a series of core-based measurements and wireline logging data interpretation that provide information about the petrophysical properties of rocks in subsurface layers. Practical projects from different fields/wells of Norway are given and students are introduced to industry relevant software for a full understanding of dealing with real data on different occasions. The principles behind petrophysical evaluation of rocks are relevant to oil and gas exploration, carbon geo-sequestration and geothermal reservoir characterization.

Content

Petrophysics attempts to integrate core-based data analysis with the wireline logs data for a complete characterization and evaluation of hydrocarbon reserves in different geological formations. In the first part of the course, students are exposed to Special Core Analysis Laboratory (SCAL) concepts where measurements to obtain reservoirs characteristics (porosity, permeability, saturation, capillary pressure) are discussed. This is followed by the wireline logging section where interpretation of lithology and determination of petrophysical properties are presented on the field scale. Different precautions and corrections are delivered in this section and volumetric reservoir estimation are exercised through a real case study from a Norwegian field.

Learning outcome

Knowledge: 

  • Interpret core data to derive petrophysical properties of rocks in laboratory. 
  • Understand the wireline logging operations, data acquisition and quality control. 
  • Interpret wireline logs data for volumetrics reserve estimation and quantification 
  •  Use appropriate software for interpretation of core, logs and well test data 

Skills: 

  • The candidate is able to perform core-based data analysis and wireline log data analysis for hydrocarbon reserve estimation 
  • Use software to analyse different logs data for reservoirs characterization 

General competence: 

  • Students should be able to analyse, and report their strategy for geological reserve estimation 
  • Be able to use industrial accepted software to implement their strategies for formation evaluation

The course has a continues assessment. All parts must be passed in order to recieve a final grade. There is no re-sit possibilities for any of the assessment parts. Students that wish to re-take assessment parts, may do so when the course is lectured. Report 1 is related to Core Analysis. Report 2 and the presentation is related to Log Evaluation. These parts is graded individually, but is closely related. Both of these parts must be completed within the same semester to obtain a grade on the "Log evaluation"-part. This also applies for students that wishes to improve their grade.Both reports is completed in groups.
