What is Slim-hole logging?
It is necessary to adopt a formal system of soil classification in the process of investigating is what soil, oil or gas is present. The only way in which this can be done is by obtaining a physical or digital sample of the ground. Not always as easy as it sounds, you’ll need to take samples, metres below the ground. When measuring multiple spots, you’ll require a tool that will be able to obtain these samples without great effort.
If this is ‘new ground’ even for your company, you’ll want to work with experienced borehole geophysical logging suppliers who are able to organise and operate the right equipment for you. Your leading provider will be able to supply logging tools such as:
Common Slimhole Testing Equipment:
- Slim Telemetry Module – This tool, often considered one of the most important allows you to collect data and combine digital data from your other slim hole testing tools and transmit them to the surface acquisition system.
- Slim Litho-Density Module – Gamma radiation is scattered by the formation before collecting data from its detectors to measure bulk and density of the soil.
- Slim Compensated Neutron Module – This tool uses dual neutron measurement to investigate formation porosity.
- Slim Dual Indication Module – A high-frequency magnetic field is created, to induce an alternating current which is recorded by the probe.
- Slim Dual Laterolog Tool – This module is suitable for medium to deep borehole logging, submits a current which is then measured to determine a disk thickness of 2ft.
Specialist logging vehicles and winches can also be provided, depending on your needs (off-road and climate). The vehicle provides compartments for probe and equipment storage as well as flood lighting and a diesel generator set. Draw-works are available in single drum configurations with a two speed hydraulic motor with a typical capacity of 4500m.
