The GR38 measure the relative naturally occurring radiation adjacent to the well hole providing well-run correlation and lithological identification. GR38 & GR25: Natural Gamma Radioactivity In addition to its primary role as a lithological or clay indicator , a Natural Gamma measurement is frequently used as the basis for establishing correlations between boreholes and to ensure accurate depth matching between different logging runs made in the same borehole. For these reasons, many LIM LOGGING probes provide this measurement as an additional log along with other parameters. The GR38 & GR25 probes provide a solution for cases where only a basic, total counts natural gamma log is required. Based on a ø25 x 50 mm NaI(Tl) and ø12.7 x 50 mm NaI(Tl) scintillation crystal detectors coupled to a high-performance photomultiplier tube, the probes boast excellent sensitivity (±1.2 cps / API unit) and provide a high quality final result.

The FWS60 transmits to the surface the full sonic waveform arriving at each receiver during a user-configurable sampling window. FWS60: Fullwave Sonic The advantage of the FWS60 tool is that it digitises and transmits to the surface the full sonic waveform arriving at each receiver during a user-configurable sampling window. For each receiver the user can choose one of three sampling periods to optimise the acquisition according to the application and/or formation characteristics. The sonic waveform data provided by the FWS60 has many applications: these include the determination of formation mechanical properties, fracture analysis, permeability and porosity estimation and cement bond assessment. According to customer preference, the probe can be supplied with three (version 3RX) or four (version 4RX) receivers. Contact us to get a quote or request more information.

The DIL38 induction conductivity probe generates an electromagnetic field and provide two simultaneous conductivity logs. DIL38: Double Induction The DIL38 induction conductivity probe generates an electromagnetic field in the vicinity of the borehole and measures the response of the formations to this applied field. On both long (ILD) and medium spacing (ILM) receivers in-phase and quadrature measurements are taken and digitised by the probe electronics for transmission to the surface equipment. In this way both formation conductivity and magnetic susceptibility data can obtained, even in dry or PVC equipped boreholes. The relatively low operating frequency and the design of the coil array combine to minimise borehole effects and maximise both depth of investigation and vertical resolution.

IP38, the formations surrounding the borehole are subjected to an alternative square-wave voltage applied via the upper and lower injection electrodes. IP38: Induced Polarisation The formations surrounding the borehole are subjected to an alternative square-wave voltage applied via the upper and lower injection electrodes. Following each injection cycle, the resulting potential difference over a section of the formations is analysed as it decreases with time. The form of this decreases curve is related to the chargeability of the formations. A high chargeability indicates that induced electrochemical potentials are able to develop within the formations as a result of ion transfer between pore fluids and semi-conductive metallic mineral grains present within the rocks. The IP38 probe is particularly suitable for mining exploration in the context of a disseminated sulphide mineralisation. In the hydrogeological domain, it can also provide qualitative information about the permeability of potential aquifer horizons. Contact us to get a quote or request more information.
