District EGR: More gas from existing fields
Description
The Oil and Gas Technology Department of the Royal Institute of Engineers (KIVI) cordially invites you to the following evening lecture
'De Wijk EGR: More gas from existing fields. What is it and what are the first results' by Martin de Boer (NAM - Senior Project Engineer).
Since the early 1950s, NAM has been extracting gas from the De Wijk field in Drenthe, between Echten and Koekange. By now, this field is almost empty. This means that we can no longer profitably extract natural gas here using standard techniques. Therefore, a new technique known from the oil industry was applied: 'Enhanced (Oil) Recovery'. In De Wijk, we extend the life of the field by 10 to 15 years with nitrogen injection and call the process 'Enhanced Gas Recovery'.
Normally, due to the natural pressure in the gas field, natural gas rises to the surface automatically during extraction. But the more natural gas is extracted from the field, the lower the pressure becomes. This means the natural gas becomes harder and harder to flow to the surface. At some point, we can hardly produce any natural gas anymore. Then we speak of an empty field. However, there is often about 10 per cent natural gas left in the field at that point. To extract even this, NAM applies nitrogen injection

Martin de Boer is senior project engineer at NAM (Nederlandse Aardolie Maatschappij). In this lecture, he will explain what EGR is, what you need to do to bring such a project to fruition and what results have already been achieved 1.5 years after start-up
