Wireline logging of water-wells can help to swiftly answer many questions that could otherwise be difficult or expensive. Data recovery is instant and interpretation happens on a timescale of hours or days rather than weeks.
RG slim-line tools can be used to investigate the lithology, porosity and permeability of rocks surrounding a water-well and to investigate the borehole fluid, its flow and characteristics.
For deeper water-wells, the RG oil/gas tool suite offers 125⁰C, 12,500psi
capability and the possibility to combine many measurements on a single trip.
Borehole location and inclination may be checked using verticality logs and correct well construction verified with a TV survey. Caliper logs provide accurate diameters and borehole volume to aid grout-volume estimations. Sonic logs (Cement Bond Logs) help to check grout integrity behind the casing.
As a well ages, it is important to check regularly for obstructions, leaks, casing corrosion and grout deterioration. All of these can hinder productivity if ignored. RG supplies a range of cameras and televiewers to give quality images in real time from within a well. and sonic tools that can give cement bond logs proving the quality of the grouting behind the casing
