Q&A on the MWD technologies in Geotechnics and deep foundations. MWD Recording drilling parameters plays a crucial role in geotechnics, special foundations, mining and underground work. By enabling data to be collected in real time during drilling operations, they provide immediate visibility of soil and rock conditions, guaranteeing precise trajectory control and work optimization. Here, we answer the most frequently asked questions about the use and benefits of drilling parameters. FAQ What are MWDs used for ? MWDs have two purposes: to control the drilling phases and to provide geomechanical/geological information on the terrain crossed by the drilling machine. How does it work ? A number of specific sensors are installed (or directly used if already present on the machine) on the drilling machine, and a recorder collects and stores this data as a function of depth every cm, in order to produce curves on the on-site recorder in real time. This data is then automatically transmitted to the cloud for specific data processing. What types of drilling machines can be equipped with MWD ? All types of machine (mining and foundation machines). Which drilling methods are best suited to MWD? For geotechnical purposes, two drilling methods are particularly suitable - destructive rotary drilling with a tricone or equivalent, and the downhole hammer for hard ground. What are the advantages of using MWDs for core drilling ? MWDs are regularly used in core sampling to understand how the core was extracted from the ground, and to explain certain anomalies in recovery rates or core conditions. What are the main MWD parameters used ? MWDs are classified into two main families - interpretative parameters and corrective parameters (A5).the main interpretative parameters are Instantaneous Advance Speed (IAV),Rotational Torque (RT),Water Pressure (WP) and Reflected Energy (RE).the main corrective parameters are Pushing Pressure (PP) on the tool and Retention Pressure (RP).the main corrective parameters are Pushing Pressure (PP) on the tool and Retention Pressure (RP). What is the use of MWD in geotechnical engineering ? MWD can be defined as a continuous qualitative in-situ test, which also has the advantage of not having any “refusals” like a static or dynamic penetrometric test. MWD is also widely used to search for voids (sinkholes) prior to construction in void and dissolution zones (gypsum, anhydrite, old mines or galleries). Why use MWDs for mining ? MWDs can be used to adapt a blasting plan to the nature of the terrain to be blasted (it is useless, even dangerous, to use explosives in fractured or empty zones). What are the advantages of MWDs in mineral exploration ? MWDs help you to better understand the geology and tectonics of the deposit concerned. What are the raw data formats of our equipment ? LIM offers its customers and the market the use of an open and documented compressed binary format (like a zip), which is described on the https://bor-form.at/en/.Les page. XML-type exchange formats do not seem appropriate to us for raw data, as the weight of an XML file corresponding to the same .BOR file is 10x to 15x larger. MWD raw data are often used by other software programs, and we recommend importing original .BOR files directly without going through the intermediate stage of XML exchange formats (AGS or DIGGS). ➭ CONTACT US

The BHTV42 sends highly focussed ultrasonic pulse radially outwards towards the borehole wall up to 360 times. Acoustic borehole imager. BHTV 42: Televiewer Acoustic Wall Imaging. Casing Thickness option BHTV 42: Casing Thickness option The BHTV42CT builds on the industry-reference BHTV42 standard acoustic televiewer probe by adding a casing thickness measurement for cased-hole inspections. As well as recording the primary echo from the inner casing surface, the subsequent parts of the signal returning to the probe are analysed for the repeating signals corresponding to the energy being re-emitted after having traversed the casing itself in both the outward and inward directions.

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.
