Researching Groundwater Protection Determinations and Data
Groundwater Protection Determinations
June 6, 2015 to Current
RRC Online System - Groundwater Application (GW-1) Database
The RRC Online System is the RRC’s online filing application system and database, located at: https://webapps.rrc.state.tx.us/security/login.do. Select the Groundwater (GW-1) Application in the “Menu Main” in the RRC Online System. The side menu includes a search called “All Applications,” which will take you to a search form with parameters that can be used to find Forms GW-1, Groundwater Protection Determination Request Form, and GW-2, Groundwater Protection Determination.
For instructions on how to gain access to the RRC Online System (e.g. Groundwater (GW-1) Application or Drilling Permits W-1 Application), visit the RRC Online System Login Page under "How to Obtain a User ID."
Fall 2008 to June 6, 2015
Groundwater Protection Determination Letters Database
You can research groundwater protection determinations in Neubus online at: https://rrcsearch3.neubus.com/ .
2001 to 2009
State Archives Groundwater Protection Determinations
The RRC’s GAU is in the process of adding groundwater protection determinations from 2001 to 2009 to the Groundwater Protection Determination Letters Database. To request a determination from this period not available online, email the GAU at GAU@rrc.texas.gov.
1956 to 2000
Micro-Filmed Groundwater Protection Determinations
To obtain hardcopies of groundwater determinations, contact the RRC's Central Records in Austin. Instructions for requesting hardcopies can be found on the RRC Oil and Gas Well Records webpage at: https://www.rrc.state.tx.us/oil-gas/research-and-statistics/obtaining-commission-records/oil-and-gas-well-records/
You can research RRC oil and gas records that may include groundwater data stored in Neubus using the Oil and Gas Imaged Records search, located online at: https://www.rrc.state.tx.us/about-us/resource-center/research/online-research-queries/imaged-records-menu/
Geophysical Well Logs
Much of what we know about deep groundwater resources comes from geophysical well logs provided by oil and gas exploration companies. The following are sources for well logs available at the RRC.
Oil and Gas Well Logs
RRC Public GIS Viewer
GAU Well Log Library
Injection Disposal Permits
Disposal Permits (Form W-14) – Neubus records of permits authorizing disposal into a non-productive formation can be searched online at: https://rrcsearch3.neubus.com
Injection/Disposal Permits (Form H-1/H-1A)– Neubus records of permits authorizing injection/disposal into a formation of productive oil or gas can be search online at: https://rrcsearch3.neubus.com.
Groundwater Data Outside RRC
Texas Water Development Board (TWDB)
Groundwater Data Webpage - Contains groundwater data and reports organized by county and aquifer. Located at: http://www.twdb.texas.gov/groundwater/data/index.asp
Water Data Interactive – Online statewide water well and well log database and geographic information system. Located at: http://www.twdb.texas.gov/mapping/index.asp
University of Texas – Bureau of Economic Geology (BEG)
Surface Casing Estimator – Website that provides estimates of well casing depths in Texas. (The information provided by the Surface Casing Estimator does not replace the need for a GAU groundwater protection determination). Located at: http://www.beg.utexas.edu/sce/
Geophyiscal Log Facility - An estimated 1.5 million logs are archived at the Geophysical Log Facility, and include the RRC collection, donated logs from industry, and logs from BEG research projects. Other datasets available at the Geophysical Log Facility include Well Records, Driller’s Logs, Strip Logs, Mud Logs, Core Analysis, and Scout Tickets from thousands of Texas wells. Contacts for and information about the facility is on the webpage: http://www.beg.utexas.edu/about/facilities/geophysical-log-facility
