Wireline logging is an electrical cable that is used to lower specific tools down holes to detect the conditions of the wellbore, which normally makes use of a specialised braided cable.
Identifying and analysing geophysical data, wireline logging is an effective method and is used industry-wide.
The term used within this article is wireline. While this is used in the industry, it is widely regarded as an ‘Americanism’, as across Europe you will know and hear it as ‘slimhole logging’.
Over the years, logging tools have changed to keep up with the demands of the industry, which means that they are now so advanced that they can measure the various patterns and details of a borehole. Acoustics, gamma, electromagnetism and much more are all able to be gauged during logging operations. Thanks to the tools of data being analysed, teams of experts are able to analyse the ground surface and draw the information and details of the land as required.
Throughout the wireline logging process, data can be tracked and analysed in real-time, or alternatively stored and recorded for data analysis at a later date. When it comes to practicality and effectiveness, it’s often advised to measure data on-site, as if the data is incorrect, can be re-evaluated and measured to ensure there are no major issues.
Without the standard of equipment we’ve discussed here, results are often-advised to measure the data on-site as if the data is incorrect and then taken away for a thorough analysis, is can become a waste of both labour and management times. Specialists will usually print off the various copies of the data.
If you want to begin logging but don’t have the required equipment, it is possible to lease the relevant and modern equipment that you can create very important data. Be sure to check both these factors that are property taken care of before you begin taking logs.
