SPE Distinguished Lecturer – Modern Perforating Techniques: Key to Unlocking Reservoir Potential

Abstract:

Perforating is a key part in any well completion, being the link between wellbore and reservoir rock. Most think of perforating as being the act of running guns loaded with shaped charges into a well on wireline or tubing and blasting holes as deep as possible into the formation. However, techniques and models have recently evolved that clearly show that the focus should be on perforating for productivity, rather than perforating for penetration. The presentation leads the audience through the research, experiments and models that show how, today, we can maximize reservoir potential through a perforated completion. It highlights the importance of not just penetration, but also shot density and perforation clean up, as well as the need to bring the well on production without damaging new perforations. The one idea I would like the members to take away from this lecture is that they should take care of how they perforate their wells and use the techniques available or risk losing thousands of barrels of production. These techniques apply to new wells, old wells and also help delay unwanted events such as production below bubble point or condensate banking. So not only wells should produce better, but they should also flow for longer without intervention. (Note that this presentation can be tailored for specific local requirements such as “Perforating for Fracturing” or “Perforating Carbonates”.

Presenter: Andrew Martin

Andy Martin is Technical Director of Perforating for Schlumberger having joined the company in 1979 as a field engineer. His career has taken him through operations, teaching cased hole services and technical writing. In 1996 Andy moved to Engineering Rosharon, Texas where perforating systems are developed, shaped charges manufactured and perforating research conducted for Schlumberger. Since then he has been involved in all aspects of perforating and regularly presents and teaches on the topic.

He is a member of SPE, SPWLA and IExE and is a Schlumberger Advisor. Andy graduated from Oxford University obtaining an MA in Engineering Science.
