Micro-resistivity imaging with the use of a new borehole probe aims to provide high resolution oriented images, which captures features such as fractures and bedding on borehole walls. The new tool is a 4-arm device which is built of four pads, each containing twelve button electrodes that are further mounted onto two pairs of powered arms.
There are a number of quality probes available for various applications such as a Neutron Probe and other borehole probes, but this new imaging probe offers new and exciting features for a variety of new applications.
When this new imaging probe is in use, each electrode emits a current which is then focussed into a narrow beam and returns to a remote part of the tool body. The current that is emitted from each electrode during this process, is then measured and digitised in each pad before going on to be transmitted to the surface by a separate telemetry module. This is with the use of a proprietary high-speed communications system. The tool may also be run on standard 4-core or 7-core cables and is compatible with standard oilfield surface systems that are available, which run Warrior software.
The probes common application involves identifying faults and folding as well as locating these issues and characteristics of certain fractures, in order to complete further investigation. Micro-resistivity as well as borehole diameter, drift and inclination are a selection of measurements which can be registered during the operation of this new tool. Many probes available worldwide operate in different conditions and whilst a Neutron Probe will operate in a water-filled open/cased borehole, the new Slim Micro-resistivity Imaging Probe operates in water-based mud.
