O'Neill Ground Water Engineering Ltd (OGE) offers
specialist downhole geophysics technology for hydrogeological
and geotechnical engineering.
The company's Irish-based service is quickly mobilised and
available throughout Ireland.
Used to determine the structural integrity of boreholes, measure
diameter, fracture depths and defines the damage to well casing.
Characterises fractures and fissures, percentage in flow at
each fracture, potential sources of contamination providing
hydrogeological solutions for the rehabilitation of wells.
Electric Logs include resistively, SP & SPR technology used
in lithological mapping to survey boreholes for geotechnical
and geological applications.
This technology is used to log and cross correlate boreholes
in specialised environments.
Enables the identification of corrosion and bio fouling and
the development of a maintenance programme for production
wells. Rehabilitation of wells can be planned without expensive
redrilling and associated costs. Boreholes and coring can
be investigated, producing a consistent record of structure
The ultimate tool in geophysical logging, the Acoustic Televiewer
provides detailed 3D information on fractures, bedding plane,
dipping and the orientation of the geological structure. This
application can be used in site investigation projects, reducing
the frequency and cost of coring.
