CAREERS IN GEOLOGY

1. PETROPHYSICIST

The primary function of petrophysicist are to ensure that the right operational decisions are made during the course of drilling and testing a well---from data gathering, completion and testing—and thereafter to provide the necessary parameters to enable an accurate static and dynamic model of the reservoir to be constructed. Petrophysicist will play a crucial role in the equity case that can be made onbehalf of his company. Clearly the petrophysicist has a duty to calculate parameters using accepted and correct methodologies  Petrophysicist has a key role in ensuring the success of a well and the characterisation of a reservoir.

 

2. MUDLOGGER

Two main responsibilities :

• To monitor the drilling of the parameters and gas/liquids/solids returns from the well to assist the drilling department in the safety and optimization of the drilling process.
• To provide information to the petroleum engineering department that can be used for evaluation purposes.

Areas in which the mud log may be particularly important include :

•          Identification of the lithology and formation type being drilled
•          Identification of porous and permeable zones
•          Picking of coring, casing or final drilling depths     
•         Conformation of hydrocarbons being encountered and whether they         are oil or gas
