HPHT wells are extremely expensive (and often carry high risk) and therefore must reach their objectives without cost over-run or incident (such as side-tracking or the incurrence of a well control event for example).
In order to drill HPHT wells successfully many specific drilling operations and procedures are employed which are quite different to those used for standard wells. This course covers those operations and procedures in detail which will maximise the success of the drilling phase of the HPHT well to be drilled.
To maximise learning, a wide range of HPHT Case Histories are also presented with delegates working through certain situations, as teams, to identify and solve HPHT problems. Presentation material is through the use of Manuals, PowerPoints, Case Histories, videos and digital film.
