SB 571 Signed by Governor

Senate Bill 571, introduced by Senator Maldonado, was approved by Governor Schwarzenegger on October 11, 2009. The bill adds Section 3724.32 to the Public Resources Code and reads as follows:

3724.32  When an operator fails to pay a civil penalty imposed pursuant to Section 3754.5, comply with an order of the supervisor issued pursuant to this chapter, or pay a charge assessed under Section 3724.5, the supervisor may deny approval of the operator's proposed well operations until the operator pays the civil penalty, complies with the order of the supervisor, or pays the charge assessed under Section 3724.5. 

Revisions to Forms for 2009

A revision has been made to the Notice of Intention to Drill a Geothermal Resources Well (Form OGG105) and to the Well Summary Report – Geothermal (Form OGG100). Effective January 1, 2009, all operators must enter the well coordinates (Lat./Long.) using NAD 83 format when submitting these forms to the Division. These forms are available from the local geothermal district office or online by clicking here.

Coproduction of Geothermal Power from Oil and Gas Fields in California: Hot water produced from oil and gas wells can be used to generate geothermal power under certain temperature and flow conditions. This report provides links to technical reports about produced water and reservoir temperatures from oil and gas fields in California. Links to electric logs and to information on temperature gradients in sedimentary basins within the State are also provided.

Published by the Division of Oil, Gas, & Geothermal Resources from 1971 through 1996, the Geothermal Hot Line has been scanned and is available online. To access the issues of Geothermal Hot Line, click here.

Amendment to Geothermal Laws Affecting Well Record Confidentiality

On September 26, 2007, SB 1051, which amends section 3752 of the Public Resources Code, was signed into law by Governor Schwarzenegger. Under the newly amended section 3752, the period of confidentiality for geothermal well records commences at the cessation of drilling operations. For more information, see the Notice to Geothermal Operators issued November 5, 2007.

 

GEOTHERMAL FACTS

Geothermal Section oversees the drilling, operation, maintenance, plugging, and abandonment of geothermal wells on state and private lands to ensure public safety and protect underground and surface waters.

California is the United States' largest generator of electricity from geothermal energy. In 2007, California received nearly five percent of its electrical energy from geothermal resources (about 13,000 Gigawatt-hours). The state has over 600 active, high-temperature geothermal wells (with fluids over 212° F) and 230 injection wells.
