Abstract

With the advancement of computer science and information technology, the oil and gas industry has been
well positioned in the data-driven business. All kinds of data, from every phase of production, are useful if they can be interpreted in a real-time manner to support optimization and development.

Reservoir surveillance, starting with the data acquisition from the well and the production network, is the driver for evaluating well and reservoir performance, then OGIP/reserves evaluation, and finally, the foundation development, on which development options are optimally selected and production optimization decisions can be made. This paper here presents the practice that a greenfield gas field adopted and many other aspects of reservoir characterization and production optimization. Focal point is to start with the permanent downhole pressure gauge (PDHG) and then, application of the real time wellhead data monitoring and recording system are the best use when putting together with the well-defined engineering methodology to support for decision making.

This is even more beneficial in the context of high operational cost and inherent high environmental risk of the high H₂S operating exposure, for the Joint Venture Gas Project in Sichuan.
