Pro-active reservoir engineering/petroleum engineering surveillance is the practice of observing and analyzing historic and real-time pressure, rate and temperature data, understanding the performance of a well/reservoir and how/why it may be changing, then managing the well to maximize the NPV and/or reserves recovery. This training will cover the basic skill sets that are required to be an effective surveillance expert.
The following topics will be covered:
1) What to measure and how to measure pressure, temperature and rates
2) The physics-based engineering equations to use to calculate:
a. Reservoir volumes (In-place, connected and mobile)
b. Skin, permeability, productivity index
c. Pressure-drop in a pipe or elsewhere in the flow system
3) How to work with automation and when to analyze things manually
4) How to hunt for ways to enhance production
While nothing can match the experience of just looking at lots of data, with these tools and philosophies, an attentive engineer can quickly become effective at pro-active surveillance. The focus of this session will be on high-rate conventional wells. We will also present some material on the surveillance of US shale wells.
