Section 1777.4 - Well Maintenance and Cleanout History(a) Unless already addressed by an approved aggregation plan under subdivision (d), within 60 days of completing an operation on a well that involves emplacing fluid containing acid in the well, the operator shall submit the following information to the Division for inclusion in the well history: (1) A description of the nature and purpose of the operation;(2) The volume of fluid emplaced in the well in the course of the operation, including specification of the gallons per treated foot; and(3) Calculation of the Acid Volume Threshold for the operation.(b) Within 60 days of completing an operation on a well that involves application of pressure to the formation that exceeds formation pore pressure, the operator shall submit the following information with the Division for inclusion in the well history: (1) A description of the nature and purpose of the operation; and(2) The bottom-hole pressure applied to the formation; and(3) Calculations used to determine bottom-hole pressure, if any.(c) This section does not apply to the following operations:(1) Well stimulation treatments regulated under Article 4 of this subchapter;(2) Underground injection project operations regulated under Sections 1724.6 through 1724.10 or Sections 1748 through 1748.3;(3) Drilling, redrilling, reworking, plugging, or abandonment operations permitted under Public Resources Code section 3203 or 3229; and(4) Replacement of equipment in the well, including but not limited to packers, pumps, and tubing.(d) Subject to approval by the Division, an operator may propose a plan for submitting aggregated information regarding a specific type of repeated operation that involves emplacing fluid containing acid in the well yet clearly does not meet the definition of a well stimulation treatment. An aggregation plan shall provide for annual submission of the aggregated volume of fluid containing acid used in an oilfield for the type of operation, a list of the wells subject to the operation during the year, and, if the operation is performed multiple times on the same well, the number of time the operation was performed on each well. An aggregation plan may be terminated at the Division's sole discretion.(e) The Division will maintain a searchable index of submissions made under this section, and the index will be made available on the Division's public internet website. The searchable index will clearly indicate each submission for a treatment that exceeds the formation fracture gradient or emplaces acid in the well and exceeds the Acid Volume Threshold, and such submissions shall include the Division's determination that the treatment is not a well stimulation treatment and the basis for the determination.Cal.
