Introduction

Well site and Operations Geology

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. This course aims to provide the required knowledge for the collaboration to be most effective and successful.
