Home My WebLink AboutItem 01 - Chesapeake Energy a EI MEMO TO: HONORABLE MAYOR, CITY COUNCIL MEMBERS FROM: BRUNO RUMBELOW, CITY MANAGERm .. SCOTT WILLIAMS, DEVELOPMENT SERVICES DIRECTOR MEETING DATE: MAY 1, 2412 SUBJECT: CHESAPEAKE ENERGY PRESENTATION REGARDING SEISMIC EXPLORATION RELATED TO NATURAL GAS DRILLING Staff has been approached by Chesapeake regarding the need to perform city wide seismic testing to maximize yields from future well drilling operations. This testing will involve the placement of sensors throughout the city, located primarily in streets, immediately adjacent to curbs. Once the sensors are in place, a convoy of specialized vehicles will travel along the lines of sensors, sending out periodic vibrations. The returns from these vibrations will be received and recorded on the sensors, creating a "map" showing optimum locations for possible gas pockets. The testing is performed by a third party firm that is contracted by Chesapeake. The oil and gas ordinance specifically exempts seismic exploration from permits. However, Staff as well as Chesapeake felt that every effort should be made to inform the public of the operations taking place. With i in mind, Chesapeake staff will make a brief presentation explaining the seismic exploration process. Chesapeake's contractor sends letters to all addresses approximately one month prior to the exploration, and 15 days prior to exploration, they hang notices on doors along the route. Additionally, technicians are spread out along the route, specifically to answer questions about the process. In addition, staff will include information on the city website, and social media sites.

This process maps the earths sub-surface and helps locate formations containing natural gas deep within the earth without disturbing surface structures. It is a safe and time tested process and has been conducted in Fort Worth neighborhoods since 2007. About Seismic Surveying and Testing The first phase of this process is to conduct a 3-D seismic geophysical survey. Surveyors walk the area with a GPS locator in a backpack to identify locations to place receiver lines and source points. These locations will be marked with either a small flag or spray painted in the easement or right of way. Approximately two to four weeks later you will see cables, geophones and data boxes placed in the neighborhood. The geophones and data boxes are secured to the ground and carry no electric current. The cable lines run along the curb and are connected to the geophones and data boxes. The cable is approximately the size of a household extension cord. Testing equipment is temporary, remaining in place for three to six weeks and takes up minimal surface space. During the testing operation "vibe buggies"will move through the neighborhood. A vibe buggy is a bit larger than a pick-up truck and lowers a mechanism to send a low-volume sound wave into the earth. This sound wave reflects off geological formations and is recorded by geophones that transfer information to the data boxes. Small vibrations may be felt and may sound like construction or a boom box is nearby. Project Timeline Survey and testing activities are scheduled to begin in your neighborhood March 6, 2012 and are expected to last until May 1, 2012. Seismic activities are scheduled from 8 a.m. to 5 p.m. Monday—Friday and 9 a.m. to 5 p.m. Saturday. Operations will be conducted in a prudent and careful manner. Homeowners or residents are indemnified and not held responsible for liability and 1 or claims resulting from our seismic testing operations.
