Who Should Attend?
These courses can be delivered either as open public training courses or in-house and typically involve additional study, assignments, and assessments. Not only do these training courses prepare you for the qualification but they also focus on providing practical skills and techniques which are directly transferred to the workplace.
Course Outlines:
Geology:
A short introduction to geology and prospecting techniques.
The Well
This section describes the process of creating the well and covers the component well equipment such as casing, cement, tubing, wellhead. The various types of the well are discussed.
The Drilling Rig
This section covers the drilling rig and its components. It describes hoisting, rotating, circulating, mud handling, pressure control, and power generation. There is an optional module describing the various types of the offshore rig and how offshore drilling differs from land drilling. Some new developments are described.
Downhole Drilling Equipment
All the components used downhole are discussed - the bit, drillcollar, drillpipe, and other accessories.
Drilling Fluids
The function of the drilling fluid, types, and properties.
Casing and Cementing
The function of casing.
Types of the casing. Design of casing strings.
The function of cement. Design of cement jobs.
Casing running and cementing procedures. Cement plugs.
Formation Evaluation
Mud logging, coring, wireline logging, MWD, LWD, drillstem and production testing are discussed.
Normal Drilling Operations
This section describes the common operations that take place during a conventional drilling process: spudding in, tripping in and out, pipe-handling, etc. illustrated with the help of animations and video clips.
Special Drilling Operations
Hole opening, under reaming, deviated drilling, continuous coring, horizontal drilling, coiled tubing drilling, multilateral, HTHP wells and underbalanced drilling.
Management
The individual job functions of the oil company operations staff and drilling contractor staff are described. Contract types are discussed such as day-rate or turnkey.
HSE
Health, safety and environmental aspects of drilling operations are discussed.
Drilling Problems
Well control, blowouts, lost circulation, stuck pipe, fishing. The theory behind well-killing operations.
Completions
What is the completion? Running the completion. Completion equipment. Types of completion such as open-hole, cased hole, single, dual, multi-laterals, smart wells, sand control, artificial lift, stimulation.
Workovers
Well servicing.
Planning
Well selection, prospect selection, the drilling program, well design, the AFE.
New developments
This section covers some of the new developments that are likely game-changers in the industry, such as automatic drilling rigs and expandable tubulars.
Abandonments
Abandonment of the well.
Documentation
The course includes a manual, hand-outs of the slides presented, and a glossary of drilling terms.
