Accurate leveling of the different profiles and boreholes, together with a topographic survey, allow us to recover long sedimentological sequences and to correlate the different sedimentary units.
Gaeta Bay, located on the Campania margin, was investigated through the interpretation of seismic reflection and borehole data together with a stratigraphic correlation of dated outcropping units.
To estimate the extent of salt water infiltration in the dune area of a Natural Reserve (Westhoek, Belgium), electrical resistivity tomography profiles were carried out together with borehole electromagnetic measurements.
If the knowledge of changing borehole thermal resistance was used together with a design program including the heat pump and its efficiency, a better BHE system design would be possible.
The third and last section focuses on using high-resolution tomographic data together with limited borehole data to infer the spatial correlation structure of log-permeability, which can be used within stochastic simulation techniques to generate parameter estimates at unsampled locations.
The surface wells together with long boreholes jointly extract gas.
Taken together, the findings from borehole resistivity logging support the hypothesized resistivity structure presented in this study.
Drilling and logging information about the 13 boreholes are provided in Table 1, and their location is shown on Fig. 2 together with the remaining nine boreholes drilled outside the Voltaian basin.
Outside the village of Kalawleh, the remains of a donkey and several goats lie together, not far from the borehole that supplies water – a cream tower that acted as a magnet for water-starved pastoralists from as far away as the border with Djibouti.
RSS ensure steering the borehole when drill string is rotating, and are usually used together with a logging while drilling (LWD) system.
