North Dee, seismic survey

IGas has commissioned a mixed-source, three-dimensional (3D) seismic survey within the CWAC authority area.

The work will be conducted by TESLA under Part 22 Class B of the Town and Country Planning (General Permitted Development) Order 1995 (GPDO).

This survey will improve the understanding of the underlying rock formations in the area and their hydrocarbon potential as well as helping to plot how deep certain strata are underground and further confirm any faulting. Seismic surveys use reflected sound waves to produce a “CAT scan” of the subsurface. 3D seismic uses geophones, devices that measure tiny ground movements, to provide a detailed set of data relating to the rock beneath our feet.

The seismic information will allow geologists to see a reliable view of the underground topography of an area. Denser data and improved computer processing ensures that subsurface features are correctly located, and can reveal the attributes which indicate the presence of hydrocarbons, rather than merely the structural elements, which could possibly contain hydrocarbons. This will complement the 2D surveys acquired by TESLA in late 2014.

A map of the planned 3D seismic survey area can be seen below.

If you wish to learn more about this survey, why not come along to the next exhibition, aimed at those people living within phase two of the seismic acquisition area. There will be staff from TESLA and IGas on hand to answer your queries.

Date: Thursday 8th October

Venue: Chester Rugby Union Football Club, Hare Lane, Littleton, Chester, CH3 7DB

Anytime from: 3pm-8pm

If you have a question about the survey, please call TESLA on 07900 603577 or email

August, 2015

IGas held a community day on 11th August aimed at local people living within the area where phase one of the seismic data is being acquired. Copies of the exhibition boards from the day can be found here outlining potential seismic activity and here with further information regarding IGas’ work.

There will be a separate community day for the second stage of seismic acquisition once the operational timescales have been finalised. IGas will distribute information to homes and businesses in that area at a later date.
