Slimline 3C Geophones

The requirement is for a borehole tool for Vertical Seismic Profiling (VSP).The VSP tool is intended to provide physical properties of formations and will allow high resolution imaging away from boreholes.The equipment is required to image and characterise the physical geology to depths of several km for both baseline purposes and monitoring of large volumes of CO2 migration.

The key science research objectives are as follows;

·Low ambient noise measurement for sensitivity to changes

·Wide bandwidth ensures higher resolution imaging

·Three component measurements for better characterisation of geology incl fluids

·Scalable architecture further shuttles/levels may be rented

·Can be used to depths greater than 4 km

The equipment comprises the following components;

·9 x units of 3 component geophone borehole shuttles with clamping arm

·Central recording system electronics mounted in 19" rack

·Bridles and interconnects between shuttles
