Participants will acquire an understanding of the geological challenges that accompany drilling and how to combat them to succeed. The course will look at what information is gathered during drilling from wellsite geology, mud logging and petrophysical (“wireline”) logs, and how it is used. The measurement and prediction of formation pressure are covered in detail, and there are also modules on coring and well testing. The course concludes with an in-depth look at the deep water drilling environment, including recent case histories. Attendees are expected to have an understanding of how petroleum is formed, how it migrates and how it is trapped, and of the principles of rotary drilling and the mud circulation system. Paper based exercises will be carried out during each module.

Dr Peter Webb
Peter joined Texaco as a Wellsite Geologist in 1974, at the start of the North Sea oil boom, alternating between the
wellsite and the office. He transferred in 1977 to Iran, initially as a Wellsite Geologist in the Zagros Mountains and
then in the office, working on the appraisal of super-giant discoveries. This was followed by 4 years in Luanda, in
operations, exploration and appraisal.
Here is what past learners have to say about this training course:
“This is a very brief, but complete course that I have never participated and was surprised with details of topic in coring &
testing. There is also a complete description on the entire task of an operation geologist.” Lead Operation Geologist,
Pertamina Hulu Energy (PHE) WMO
“As a Geophysicist, I found it this course very resourceful and I had learned a lot about the operations. I can now speak the
same language as the drillers after attending this course.” Geophysicist, Talisman Malaysia

Course highlights
 The Instructor is a currently active exploration consultant with 40 years of international industry experience, including
training and mentoring.
 The course covers concepts and case histories that are at the forefront of the modern offshore petroleum industry.
 Hands-on exercises are used to reinforce the theoretical concepts.
By attending this training, you will know about:
 The information that is obtained during the drilling of a well, its purpose and limitations.
 How that information is used to monitor well progress, make decisions during drilling, and mitigate risks, thereby
maximising company’s return on its investment.
 How formation pressure is generated, how it can be predicted, and what can go wrong if it is not properly understood
and managed.
 Why and how coring and testing programmes are carried out in wells and how the information thus obtained is used in
determining whether or not a discovery is commercial, and in formulating the Field Development Programme.
 The conditions peculiar to the deep water offshore oil and gas exploration and production theatre.
Who should attend?
 Exploration, Development, Wellsite and Operations Geologists
 Petrophysicists
 Drilling Project Managers

A move to Sun International in 1984 saw him in Colombia for two years as Exploration Manager, followed by operations
and new ventures studies in countries as diverse as Sudan, Argentina and the UAE. In 1992, he formed his own consultancy
but moved to PNG to work for a World Bank project from 1995 to 1998, and to Cairn Energy India from 2000 to 2004. He
continues to consult, mainly in new venture evaluation but has also undertaken a number of training assignments,
including all of 2009 on the super-giant Kashagan field in Kazakhstan. As independent consultant, Pete has taken-up
assignments with Roberson Research (UK), Knowledge Reservoir, MND A.S. and OPC.
At home in the UK, he gives public lectures, especially on fraccing for oil and gas. Pete is a member of the AAPG, where he
was an Associate Editor on the Bulletin from 1994 to 2004. He is also a Chartered Geologist and Fellow of the Geological
Society (London), and a member of the Petroleum Exploration Society of Great Britain. Pete Webb is a graduate of London
University, England, holding a BSc in Geology and a PhD.
