The BDV probe is designed to provide continuous measurement of borehole inclination and azimuth. BDV42: Deviation du Forage The BDV42 probe is used to determine the exact drilled trajectory of a borehole in the subterranean space. Boreholes drilled close to infrastructure such as cables or tunnels can be surveyed before reaching the critical point. Another application of this method lies in water well quality control by ensuring that well deviation and curvature criteria are met so that problems with lowering pumps and other equipment can be avoided. The probe is based on a high-precision c ombination magnetometer and accelerometer sensor providing a continuous measurement of borehole inclination and azimuth. Because of the resulting magnetic disturbance, reliable azimuth data can not be obtained in steel-cased wells or in iron-rich geological formations.

PDS, Probe Deployment System, Borehole logging horizontal boreholes, Borehole logging upward boreholes. PDS: Probe Deployment System The PDS allows OPTV and BHTV imaging probes and certain other types of probe to be deployed in steeply inclined, horizontal or up-holes, where assistance from a drilling machine is required. It has been successfully used in boreholes exceeding 400 m in length. The main housing containing the probe is manufactured from aluminium and the standard kit includes 2 x 2 m aluminium rods to allow imaging probes to operate in non magnetically disturbed conditions. A variety of nose cones, adapted to different types of probe, and housing centraliser blades for boreholes of up to 150 mm diameter can be supplied. Behind the housing the logging cable runs along the outside of the drill rods (AQ or BQ recommended). The drill rod adapter incorporates a centraliser to support the weight of the drill string. A precise depth measurement is obtained using the lateral movement of the drilling machine’s drive head. Contact us to get a quote or request more information.

The BHTV42 acoustic imaging probe or acoustic televiewer with casing thickness option is used to measure the thickness of a drill casing. It uses a rotating transceiver mounted at the lower end of the tool, which sends a beam of highly focused ultrasonic pulses towards the borehole wall (up to 360 times per pulse). 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.

3AC, 3 arms caliper. By means of three spring-loaded arms maintained in contact with the borehole wall, the 3AC38 probe provides a representative measurement of the borehole diameter. 3AC38: Three-arm caliper probe By means of three spring-loaded arms maintained in contact with the borehole wall, the 3AC38 probe provides a representative measurement of the borehole diameter. The standard probe nose section and arms provide a high-resolution measurement over the diameter range from 40 to 300 mm. If the supplied arm extensions and nose section extension tube are installed, the upper diameter limit is increased to 700 mm. As an indicator of enlarged zones or fractures, this log is useful both in assessing the competence of the formations and as a basis for calculating environmental corrections for other logging parameters such as fluid flow and production assessment. The basic open-hole diameter log can be integrated over depth to calculate an accurate borehole volume for cementing or gravel-packing operations. The probe is also useful for quality control purposes, for example to verify the depth and diameter of casings and screens installed in a water well. As an option, the probe can be supplied with a natural gamma detector to provide additional lithological information or for horizon corelation purposes.

GRT38, Gamma ray temperature probe. GRT38: Natural Gamma + Temperature + CCL 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.
