- Mud Engineering: functions, types, properties;
- Drilling Procedure: straight, directional, multilateral, and extended reach drilling;
- Well Completions and Oil well Casing: fracture gradient, functions, types, properties, specification and casing design, well completion practices, open hole-, perforated-, sand exclusion-, permanent-, multiple zone-, and drainhole completions, wellhead, lifting;
- Cementing: functions, classes, types, properties;
- Hole problems: pipe sticking, lost circulation;
- Waste, waste management;
- Abandonment.

Production Engineering

- Performance of Productive Formation: productivity index, inflow performance relationships, gas well productivity, generalised pressure functions;
- Flow of Fluids in Pipes: general energy equation, static bottom hole pressure, friction factor;
- Gas Lift: continuous gas lift, gas lift valves, compression requirement;
- Processing: separation and treatment of well fluids, conventional stage separation, gas-liquid mixtures, water-oil mixtures;
- Processing of Gas Condensates and Natural Gases: absorption and stripping, hydrate formation and prevention, dehydration and sweetening of natural gases;
- Hydrocarbon Transportation and Storage: pipelines, multiphase flow, pumps and compressors.

Study-unit Aims:

The study-unit aims to provide the student the knowledge and understanding of planning wells, drilling, completion, testing, well treatment, and field development.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to understand the:
- Principles of drilling procedures and equipment;
- Design of a well program;
- Preparation of site and other work leading to drilling;
- Principles of well completion and testing;
- Drilling and production waste management;
- Function of production facilities;
- Principles of field management including well simulation and export.

2. Skills:

By the end of the study-unit the student will be able to:
- Design a well drilling program including casing and mud programs for a variety of well prognoses;
- Design the completion and testing of a well;
- Formulate a field development and management program.
