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.

Le LIMBoat est une solution pour le suivi des paramètres de forage lors des opérations offshore. Basé sur notre enregistreur PocketLIM, LIMBoat permet de mesurer en temps réel la profondeur, la vitesse d’avancement, les charges hydrauliques, le débit et la pression du fluide injecté, ainsi que d’autres paramètres sur demande. LIMBoat : Offshore drilling LIMBoat is a solution for monitoring drilling parameters during offshore operations. Based on our PocketLIM recorder, LIMBoat measures depth, advance speed, hydraulic loads, flow rate and pressure of the injected fluid in real time, as well as other parameters on request. The system can be adapted to any vessel: measurements via pulleys, multiple encoders, or winches equipped with wave compensators for great depths. As each project is unique, a preliminary technical visit is carried out to define the measurement points and ensure optimal integration of the LIMBoat for reliable and efficient monitoring. Main parameters recorded: -Instantaneous forward speed -Fluid flow rate and volume -Injection pressure -Torque and rotation speed Other parameters can also be measured on request.

Our ScanLIM LIBS option project aims to combine, in a single tool, high-precision optical digitisation for the geologist and the metal content of drill cores for the miner, by miniaturising the data. high-precision optical digitisation for the geologist and the metal content of drill cores for the miner in a single tool, by miniaturising LIBS (Laser-Induced Breakdown Spectroscopy) technology. ScanLIM LIBS - JV LIM-ABLATOM Our ScanLIM LIBS option project aims to combine high-precision optical digitisation for the geologist and the metal content of drill cores for the miner by miniaturising LIBS (Laser-Induced Breakdown Spectroscopy) technology. The economic aim of our project is to make this dual tool (optical and LIBS technology) transportable, so as to reduce sample (core) analysis times by being as close as possible to the drilling machine. All that will be required is a basic shelter such as a site core box with a power source. This proximity between the core extraction site and the on-site optical and LIBS analysis of the samples will save time and money, as it avoids the need to send all or part of the core boxes to the Chemical Analysis Laboratory to obtain the desired results.

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.
