For many years, oil and gas producers have been in some manner “managing” produced solids at surface mostly as part of a reactive rather than a structured and planned strategy. This process has consisted mainly of separation, removal and solid’s disposal activities. Adopting a sand management strategy is not always a deliberate decision but can be a consequence of previous production strategies in which sand production was not identified as a potential problem at the time. In this case, unless it is a field re-development, development and implementation of sand management strategies have proven to be much more difficult. Issues such as cost, space limitations and environmental concerns make the implementation of these strategies very complex if not impossible. This course starts by addressing the downhole issues such as sand failure, its causes and remedies in order to allow the attendant to understand the complete sand production process from the reservoir to surface. The course completes the cycle covering the remaining aspects of the problem from when sand particles enter the wellbore to the safe and efficient disposal of it. The material makes an emphasis on the components of the process. These are:
Effective sand particle transportation from wellbore to surface
Safe and efficient removal/separation of the solids on surface
Environmentally compliant and cost effective disposal of the separated particles
The material presented in this course is focussed on the technical, operational and economic aspects of these three (3) steps.
