Document Description
This project will develop, in a laboratory, and demonstrate, at an existing natural gas storage facility, a downhole multi-sensor array based on fiber optic sensing technologies to monitor natural gas storage reservoirs. This multi-sensor array will include all-optical pressure, acoustic, strain and temperature sensors to provide real-time monitoring. The purpose of this project is to detect pre-failure micro-seismic noise, excessive strain, and any small leaks. The beneficiaries of this project include

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit 14, § 15301 ; Cal. Code Regs., tit 14, § 15306
Reasons for Exemption
California. Code Regs., tit 14, section 15301 provides that projects which consist of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, and which involve negligible or no expansion of existing or former use, are categorically exempt from the provisions of the California Environmental Quality Act. This project will consist of laboratory testing and field testing of fiber optic sensors to monitor natural gas storage reservoirs. The laboratory testing will be conducted in an existing laboratory, using existing equipment in the laboratory. The field testing will be conducted at an existing borehole at an existing PG&E's natural gas storage facility, where the fiber optic sensors will be placed inside a 2 3/8” tube within the 5,300-foot-deep borehole. In addition, a 160 square-foot, partially air-conditioned instrument storage container will be placed next to the wellhead. These modifications will not result in expanding the capacity or use of the facility.
