In order to ascertain whether a structure contains oil or gas, a well has to be drilled through it. One can get important information from the well, such as drill cuttings, cores and different logs.
From these data one can ascertain whether there is oil or gas in the well, and further information about the quality of the reservoir, If the results are promising, one or more zones in the well are sometimes tested - either with a wireline formation tester - so-called mini test - or a drill- stem test (DST). If the results of the test are good, more appraisal wells are drilled to map the extent of the field.
Primarily in this Basic Drilling Technology online training course we emphasize the modern ways of drilling in a cost-effective approach while we explain how the field is thoroughly evaluated. This includes estimating the volume of hydro - carbons in the field, consideration of drive mechanism and the expected formation pressures. This forms the basis for the field development plan. Cash flow, capital and operating expenditure for the field are estimated following the drilling sequence and the production tests, so that the profitability can be considered. If the economic evaluation of the field seems positive, it is deemed commercially viable and can therefore be developed.
This Basic Drilling Technology online training course will clarify in-depth the drilling of Exploration wells. Also we meet other terms for these wells like Wildcat, Appraisal wells, Development wells or production wells. During the online training course the drilling rigs will be presented together with full description of basic components of the rig.
The PetroKnowledge online training course will feature:
- Introduction to special drilling for highly deviated wells or horizontal ones and the practical means and tools to achieve these demanding works.
- Estimated TD, production potential.
- Geological prognosis considerations prior to start drilling activities
- Casing and cementing design
- Coring and open hole logging
