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 work on Routine- and Special Core Analysis (RCAL/SCAL) concepts. Important reservoirs characteristics are introduced including porosity, permeability, saturation, pore size distribution, wettability and relative permeability- and capillary pressure functions. These parameters are directly relevant in reservoir simulation. Methods to perform relevant experiments and interpret the data to calculate these parameters are presented. Practical lab work is performed and calculations on data are performed with commercial industry relevant software. 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.

Continuous evaluation.You must pass all parts to pass the course. All parts must be assessed in order to receive a grade. If you fail an assessment, you can retake it the following year. There are no continuation opportunities on the assessment parts. Students who wish to take these sections again must do so the next time the course has regular instruction.
