Description

Reservoir Management Challenges in Commingled Wells … and ways to overcome them

 

Speaker: Nick Last

Well Test Knowledge International

Perth, Australia

 

Abstract:

Commingled completions are a cost effective strategy to produce from multiple independent stacked sand reservoirs. They are widely used across the Asia Pacific region, especially for gas production, and have been implemented in a variety of well types ranging from simple 2-7/8" monobores in the Gulf of Thailand to large bore sub-sea completions offshore Western Australia.  But commingling presents a number of reservoir management challenges, including allocation of production back to individual zones, identifying the distribution of resource between those zones, and dealing with water influx that can shorten the well's life dramatically. This talk highlights the differences in behaviour between commingled and conventional single-sand completions, and examines various surveillance and well analysis options that can shed light on the resource distribution and help to optimize ultimate recovery.

 

Bio:

Nick Last started his career with Schlumberger in the North Sea in the 1980’s, working as a well test supervisor, logging engineer and well test interpretation specialist, before moving to Thailand as Location Manager. Since leaving Schlumberger he has consulted for numerous Operators throughout SE Asia and Australasia, specializing in developing testing and surveillance strategies and making sense of the resulting data. He has been wrestling with the challenges of commingled gas production for two decades, and has used that experience to teach numerous classes on well testing, production log and pressure transient interpretation, and commingled reservoir management. Nick is currently Director of Well Test Knowledge International in Perth, Western Australia.
