Well Engineering
Highlights:
This is the most intensive course in our portfolio and is intended for those who want to learn , succeed and be the best.
This course has been attended by every major oil company in the North Sea and many oil and service companies from around the world. The repeat running of this course and the many excellent reviews indicate that this course is one of the best technical courses available in the petroleum industry.
Audience:
This course is suitable for Drilling Engineers, Drilling Supervisors, Toolpushers, Petroleum Engineers, Asset Team Members and Project Management Members wishing to understand the engineering details involved in the planning and drilling of oil and gas wells. The participant should have a basic understanding of the oil industry and have a University or equivalent education.The participants should expect to work for a minimum of 12 hours a day: 8 hours tuition and 4 hours homework. A laptop is recommended and should be loaded with Excel.
Learning Outcome:
The participant will be able to assemble well data from various sources, understand their relevance, produce a well design fit for purpose including casing seat selection ( Frac/pore pressure), selection of casing weights and grades, hydraulics, drillbits and BHA designs.
The following handouts will be given:
1. Well design manual
2. various Excel sheets
3. Certificate from United Education on completion of this course.
