Scope

NB/T 11442-2023 is the English-translated version of 煤层气田开发可行性研究方案编制规范.

NB/T 11442-2023 tells coalbed methane developers what to put in the feasibility study report for developing a gas field from the surface in a block with proven reserves.

It first sets the preparation conditions: purpose and tasks, the exploration and pilot development work that must already be complete, the basic data and preparation principles.

The content clauses then cover an overview of the field, market analysis, gas field geology and reservoir engineering, drilling, fracturing and gas production engineering, surface construction works, health, safety and environmental analysis, and investment estimation with economic evaluation.

Related NB/T, GB/T and SY/T coalbed methane codes are referenced throughout. Issued on 28 December 2023, it has applied since 28 June 2024.
