A set of knowledge domains facilitating Upstream operations:
Petroleum Geology | Studying reserves structure and volumes |
Rock Geomechanics | Studying response of rock and rock masses to the forces or displacements |
Petrophysics | Studying rock properties |
Well & Log Analysis | Designing and interpretation of well logs |
Well Testing | Designing and interpretation of well tests |
Fluid Analysis | Modelling fluids produced from or injected into the petroleum reservoir |
Reservoir Flow Simulations | Modelling well and reservoir flow dynamics and generating forecasts |
Production Technology | Well Performance Analysis and production optimization |
Drilling | |
Workover Engineering | |
Field Development Planning | Creating Field Development Plans |
In most common sense this set is equivalent to what is also called Field Study and Modelling.
