A4: To discuss the future challenges for subsea engineering.

Outline Of Syllabus

1. Origin of Oil and Gas (3 hours): Overview of the generation of oil and gas, including; types, sources, characteristics and transport in source rock.

2. Reservoir Geochemistry (3 hours): Principles of reservoir geochemistry and applications to exploration, production and appraisal.

3. Drilling Engineering (6 hours) : Overview of the drilling process including rig, hoisting and drill string design, drill bits, fluid flow, rig hydraulics, straight hole drilling, directional drilling, slant and horizontal drilling, fracture gradient casing design, cementing, hole problems and finishing, well control, well bore completion, subsea tree and blow out prevention.

4. Metocean and Environmental Conditions (6 hours): Overview of the determination of metocean conditions (meteorological and oceanographic) and the influence of wave, wind, tide and current on marine operations. Introduction to marine ecology and its impact on marine operations.

5. Subsea Structures and Architecture (3 hours): A description of each of the pieces of the subsea infrastructure, their use and interconnection including subsea trees, flowlines, umbilicals, risers, moorings and pipelines.

Teaching Rationale And Relationship

Directed study and the formal lectures will provide an effective method for students to assimilate the knowledge content, define the scope of the syllabus topics and attain the required knowledge and skill (ISO1-2) outcomes. The directed study allows students to work through material at their own pace allowing them to develop an in-depth understanding of the material (IKO1-5).

Assessment Rationale And Relationship

The exam tests acquisition of a clear general knowledge of the subject plus the ability to think and analyse a problem quickly, to select from and to apply both the general knowledge and detailed knowledge of aspects of the subject. The exam also assesses problem solving skills, the ability to work unaided and to communicate clearly and concisely in writing. The essay provides students with the opportunity to demonstrate their numerical analysis and information literacy skills. The coursework also assesses written communication skills.
The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
