A Preliminary Practice on Development Evaluation of Gas Field

��The development evaluation of gas field is a policy decision method proposed in practice for gas field development investment. The objects are to speed up the development process of gas field and draw up the reasonable distributive well pattern, as well as to work out and optimize the development evaluation project using numerical simulation and economic analysis, so as to offer a evidence of policy decision for gas field development investment. This article uses the practice on the development evaluation of C₂ reservior in SGP gas field as an example to introduce some ways applied for development evaluation of gas field.
