1 OPTIMISED DRILLING PRACTICES C o n t a c t U s f o r S p e c i a l C o r p o r a t e R a t e N o w!

2 Course Overview This course covers Optimising Drilling Operations (and those other areas Drill Crew & Operators are involved with such as cementing, coring, logging, testing and well abandonment for example) through the media of:- 1) Lectures (the Trainer began his career 35 years ago and has worked worldwide on a wide variety of wells on La d rigs, JU s, e i-submersibles, Platforms, Tenders and Drill Ships); 2) PowerPoints (written by the Trainer); 3) Videos; 4) Case history examples; 5) Teamwork exercises. New technologies available to the Industry are also covered. Provision is also made for delegates to discuss any of their well(s) which are pertinent to their particular upcoming projects in order to secure maximum success first time. For each subject area, benefits of certain industry practices are covered in detail as well as why difficulties are encountered on the rig. Solutions are presented (e.g. optimal drilling and practices per IADC) so that the well to be drilled is a success first-time. Aims & Objectives By the end of the course, delegates will understand the key drivers behind successful Drilling Operations so that their wells are both drilled economically and are successfully, meeting all their objectives. Delegates will also benefit from success and failure stories of drilling operations worldwide and what can be done to maximise success first time and minimise failure. Consultancy services can be provided both before the course (e.g. certain wells / problems can be looked at), during the course (e.g. certain problems can be reviewed) or after the course (e.g. advice / well review) should delegates require. Who Should Attend Assistant Drillers, Drillers, Toolpushers, OIM s, Drilli g E gi eers, e ior Drilli g E gi eers, Offshore Drilli g Engineers, Offshore Supervisors, Drilling Superintendents, Service Company Personnel.
