Oil and Gas

Participants will learn to:

1. Compare drilling operations, both onshore and offshore and understand the differences between the various types of rigs and platforms.
2. Distinguish the various components of the drill string: hoisting and rotating systems and pipe handling equipment, bit types and their design and application; the mud circulation process and system; the variety of drilling fluids and well hydraulics; casing and cementing procedures; directional drilling processes and techniques; borehole surveying. 
3. Appraise mudlogging services including: the collection and analysis of ditch cuttings and lag time estimation; depth and bit parameter measurements; the collection, analysis and integration of gas readings;  the wider role of mudlogging in safety monitoring and drilling engineering support.
4. Analyse how ditch cuttings are sampled, described, reported, logged and evaluated for lithological evaluation and hydrocarbon potential.
5. Compare conventional coring and sidewall coring processes, procedures and evaluation techniques.
6. Distinguish the acquisition, processing and basic interpretation of wireline from LWD logs, and their integration with other wellsite derived geological data.

Participants will learn:

• About well planning and rig selection
• About the drillstring, bits, drilling fluids, casing and cementing, well control and directional drilling
• How wellsite geologists and mudloggers collect and interpret geological and drilling data
• About coring, wireline logs and MWD Services
• How to evaluate and describe drill cuttings and oil shows from practical work
