Geo-Physical in-situ borehole surveys Winch :

The system is equipped with slip ring and connections through which surface instrumentation can communicate withthe probe. A precision measuring wheel and rotary encoder are also included to allow the amount of cable played out to betracked. The cable is automatically wrapped on the drum in even layers through the level wind mechanism. The motor iscontrolled by a 110V (or 220V depending on the model) four-quadrant motor speed controller that allows the speed toremains constant with a varying load and prevents overhauling with heavy loads. Dynamic electronic brake is a standarditem

Geo-Physical in-situ borehole surveys Slimhole acoustic Televiewer

Applications :

Fracture detection and evaluation in muddy and or oil filled holes

Detection of thin beds Determination of bedding dip Lithological characterization Breakout analyses Monitoring of earth stress field Casing inspection (inner corrosion only) High resolution hole diameter

measurements

Can be used in zero visibility conditions, i.e. mud & oil filled holes

Geo-Physical in-situ borehole surveys Three arm caliper

Application

It records a single continuous borehole diameter log by means of three mechanically coupled arms in contact with the borehole wall. The 3 arm caliper measurement is a useful first log to determine the borehole condition before running other probes – to assess the possibility for the probes to get stuck in the hole due highly fracture zones
