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 FTC60 probe provides precise readings of the flow speed of the fluid, the temperature and the electrical conductivity contained in the borehole. FTC60: Temperature/Conductivity/Flow The FTC60 probe provides precise readings of the temperature, electrical conductivity and flow speed of the fluid contained in the borehole. Its main applications are in obtaining groundwater quality and production data in hydrogeological or pollution studies , either on a single or multi-well regional basis. Another possible application is the detection of setting cement by means of the heat given off during this process; for example in a borehole after casing installation and grouting or in quality control of cement piling works. The lightweight impeller and low friction bearing assembly permit this probe to react almost instantly to any vertical movement within the fluid column of a well or borehole. The direction of flow relative to the probe can be determined from the sense of rotation of the impeller. Contact us to get a quote or request more information.

GRT38, Gamma ray temperature probe. GRT38: Natural Gamma + Temperature 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 GRT38 probe provides a solution for cases where only a basic, total counts natural gamma log is required and also provides a borehole fluid temperature measurement useful for correcting certain other logs. Based on a ø25 x 50 mm NaI(Tl) scintillation crystal detector coupled to a high-performance photomultiplier tube, the probe boasts excellent sensitivity (±1.2 cps / API unit) and provides a high quality final result. For clients requiring this additional parameter, the probe can be factory fitted with a casing collar locator (CCL) detector. Contact us to get a quote or request more information.
