Wellsite Geology & Operations
Alice Post
5 * 4 hours online
Business context
A large amount of geological data is acquired albeit at a
substantial cost when carrying out a drilling operation. Ensuring
optimal quality of this information and effective reporting plays a
key role during the well design and drilling operations. In
addition, there is much to benefit from the later usage of the data
in field studies.
A critical component that ensures favourable and positive
results requires close co-operation between geological, drilling
and well engineering departments. Comprising of 5 half-day
sessions, this Virtual Instructor Led Training (VILT) course aims
to provide the required knowledge in order for the collaboration to
be most effective and successful.
Who should attend
This VILT course is intended forgeologists and other subsurface
staff involved in drilling operations who would like to work and
communicate more effectively with the wellsite staff.
Please note that this VILT course is not a preparation course
for a wellsite assignment.To be able to work independently on the
wellsite, a more hands-on or on-site training would be
required.
Course content
At the end of this VILT course, participants will be able
to:
- Understand the techniques used by wellsite geologists in
formation evaluation via:
- quick-look analysis to assess reservoir and hydrocarbons
- mudlog data (lithology/cutting description, gas readings)
- Grasp the application of wellsite data in exploration and
development
- Read and use drilling reports
- Acquire an understanding of the drilling problems caused by
subsurface conditions
- Understand the role and contributions of the geologist to the
well maturation process
Learning, methods and tools
The VILT course will comprise lectures interspersed with
practical and interactive exercises and quizzes to promote better
understanding.
