Oil & gas wells are often extremely expensive (and often carry high risk) especially if they are long-reach / horizontal / multi-lateral and therefore they must reach their objectives without cost over-run or incident (such as worn or corroded casing, excessive lost circulation or an underground blowout for example).
In order to drill wells successfully many aspects of engineering must be assessed, such as wellheads, drill bits and drilling assemblies, casing properties, drilling fluids, cementation, drilling equipment in general, the rig and its crew, the well’s objectives etc. which will differ between the exploration, appraisal and development phases.
This course covers those engineering aspects in detail which will maximise the success of the drilling phase of the well to be drilled.
To maximise learning, a wide range of Case Histories are also presented with delegates being given the opportunity as teams to design their own well. Presentation material is through the use of Manuals, PowerPoints, Case Histories, videos and digital film.
