1 Scope

GB 42294-2022 is the Chinese national standard on safety code of practice for onshore petroleum and natural gas exploration and production, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 29 December 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2024. Classification: ICS 13.100, CCS E09. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the production safety requirements for onshore oil and gas exploration operations. This document is applicable to the exploitation of onshore oil and gas (including shale gas), and the exploitation of coalbed methane can be used as a reference.
