Well Log Analysis
Characterisation of the rock matrix, the reservoir and operating conditions
Why this service is important
The interpretation of well logs transforms measurement results into insights regarding lithology, the petrophysical properties of rocks, porosity, permeability, saturation, the presence of reservoir fluids, flow conditions, the technical condition of the well and its production potential.
GT’s offer
GT carries out standard and specialist interpretations of data from open, cased and production wells. These services are used in projects relating to hydrocarbon reservoirs, geothermal energy, mineral resources, underground storage and the assessment of well condition.
Well data interpretation is carried out by a specialist GT team using the company’s own hardware and software infrastructure and dedicated interpretation packages. This enables the integration of well logs with geological, seismic, petrophysical and production information.
Technologies and operational advantages
The scope of work includes well data analysis, inter-well correlations, lithological and petrophysical characterisation, reservoir parameter assessment, identification of prospective horizons, well condition analysis, and preparation of results for further geological, reservoir and design analyses. Modern well data interpretation utilises multidimensional statistical methods, electrofacial classification, big data analysis, machine learning and the integration of well measurements with geological and seismic models. Another key element of our service offering is the digitisation, standardisation and reinterpretation of archived data.
Value for the client
The client receives practical knowledge about the rock formation, the reservoir and the well, supporting resource documentation, drilling planning, the selection of operating parameters, production optimisation and the assessment of drilling and production risks.
