BASIS FOR THE WELL STIMULATION RULES:
Four major issues were addressed:
1. the protection of groundwater and the identification of permitted water supply
wells within ¼ mile of the drilling and spacing unit or Commission approved
drilling unit;
2. clarification of requirements for well integrity, casing setting depths, casing
design and cementing properties;
3. requirements for disclosure of well stimulation fluid chemical additives,
compounds and concentrations or rates – planned and actually injected;
4. and requirements for the handling of the well stimulation load fluid recovered.
