Release Date: February 28, 2022

Today we amended subsurface orders 1B, 3A, 4, and 5. The amended subsurface orders have been renumbered as 1C, 3B, 4A, and 5A and published on our subsurface orders webpage.

These subsurface orders were amended to align them with changes to our regulatory framework for oil and gas well testing (Bulletin 2021-34), coalbed methane control well requirements (Bulletin 2021-29), and well spacing requirements (Bulletin 2021-14). 

We use subsurface orders to adapt our regulatory requirements for specific geological zones over specific geographic areas to best suit energy resource development in those areas. However, recent changes to Directive 040: Pressure and Deliverability Testing Oil and Gas Wells, Directive 065: Resource Applications for Oil and Gas Reservoirs, and the recission of Directive 062: Coalbed Methane (CBM) Control Well Requirements and Related Matters has eliminated the need for some of the exemptions granted in previous versions of the subsurface orders.
