California Code of Regulations › Title 14 - Natural Resources › Division 2 - Department of Conservation › Chapter 4 - Development, Regulation, and Conservation of Oil and Gas Resources › Subchapter 1 - Onshore Well Regulations › Article 4 - Underground Injection Control › Section 1724.7 - Project Data Requirements

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) An underground injection project shall be
					 supported by data filed with the Division that demonstrates to the Division's
					 satisfaction that injected fluid will be confined to the approved injection
					 zone and that the underground injection project will not cause damage to life,
					 health, property, or natural resources. The engineering study, geologic study,
					 and injection plan described in subdivisions (a)(1) through (a)(3) shall
					 demonstrate to the Division's satisfaction that injected fluid will not migrate
					 out of the approved injection zone through another well, geologic structure,
					 fault, fracture, fissure, hole in the casing, or other pathway, considering
					 project duration, volume of fluid to be injected, and other relevant factors.
					 The operator is responsible for ensuring that the data are current and
					 accurately reflect the project setting and operation throughout the operating
					 life of the project. The data filed with the Division shall include, at a
					 minimum:
(1) An engineering study, including
					 but not limited to:
(A) A description of how
					 the area of review was determined, including calculations, variables,
					 citations, and assumptions.
(B) A
					 map of the area of review showing the location of the following:
(i) All wells within and adjacent to the
					 boundary of the area of review;
(ii) All water supply wells that are within
					 the area of review and identified in public records or otherwise known to the
					 operator;
(iii) Any underground
					 disposal horizons, mining, and other subsurface industrial activities not
					 associated with oil and gas production within the area of review, to the extent
					 such information is publicly available or otherwise known to the operator;
					 and
(iv) Traces of the geologic
					 cross sections provided under subdivision (a)(2)(E).
(C) A compendium of the following
					 information:
(i) For all wells depicted in
					 subdivision (a)(1)(B) (including water supply wells to the extent information
					 is known or publicly available), the API numbers, or other identifying
					 information for wells that do not have API numbers, and the wellbore paths,
					 total depths, and depths of completion interval(s) of the wells;
(ii) The type and status of water supply
					 wells depicted in subdivision (a)(1)(B); and
(iii) All data specified in Section
					 1724.7.1, provided in the form of
					 graphical casing diagrams or flat-file data sets, for all wells that are within
					 the area of review and that are completed in or penetrating the injection zone
					 for the underground injection project or a deeper zone, including directionally
					 drilled wells that intersect the area of review in the injection zone or a
					 deeper zone.
(D) The
					 planned well-drilling and plugging-and-abandonment program to complete the
					 project, including a flood-pattern map, if applicable, showing all injection,
					 production, and plugged and abandoned wells, and unit
					 boundaries.
