Document Description
THUMS proposes to rework existing oil and gas well in the Wilmington field Offshore Island Freeman (D-822). The rework consists of running inner liner inside the existing wellbore and returning the well to its existing use. These wells fall under Group A, of CalGEM’s rework exemptions guidance document published in December 2023.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving 1 permit for THUMS Long Beach CO. to rework the well listed below, in the Wilmington Oil Field.

Reasons for Exemption
The basis for CalGEM’s determination that the project is exempt from the requirements of CEQA is provided in the brief explanation below.
The Operator has submitted an NOI to install an inner liner inside the existing wellbore and returning the well to its existing use. The inner liner will serve as sand control, the current liner is compromised which leads to premature pump failure.
Class 1, Existing Facilities (14 CCR §§ 15301, 1684.1):
Class 1 consists of the “operation, repair, maintenance, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features involving negligible or no expansion of use beyond that existing previously.” This includes “remedial, maintenance, conversion, and abandonment work on oil, gas, injection, and geothermal wells involving the alteration of well casing, such as perforating and casing repair, removal, or replacement; installation or removal of downhole production or injection equipment, cement plugs, bridge plugs, and packers set to isolate production or injection intervals.” (14 CCR § 1684.1.) The proposed project would make minor alterations to the well(s), resulting in negligible expansion of use beyond that existing previously. The proposed project and related permit approval is consistent with the laws that govern the operations, including statutory and regulatory provisions that protect public health, safety, and the environment.
Class 2, Replacement or Reconstruction (14 CCR § 15302):
Class 2 consists of the “replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced[.]” (14 CCR § 15302.) The proposed project would reconstruct the casing and wellbore(s) of existing wells. The work would take place on the existing wellbore(s) and well pads. The proposed work involves negligible change in use of the wells. The proposed project and related permit approval is consistent with the laws that govern the operations, including statutory and regulatory provisions that protect public health, safety, and the environment.
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2):
Class 4 consists of “drilling operations that result only in minor alterations with negligible or no permanent effects to the existing condition of the land, water, air, and/or vegetation.” (14 CCR § 1684.2; see also 14 CCR § 15304.) The proposed project involves negligible or no vegetation removal, expansion of the existing well pads, and ground disturbance. Therefore, there would be no surface disturbance related activities that would significantly disturb the surrounding environment. The proposed project and related permit approval is consistent with the laws that govern the operations, including statutory and regulatory provisions that protect public health, safety, and the environment.
