The Importance and Applications of Well Logging
The process of extracting the detailed records of geologic formations made by a well or a borehole is called well logging. It helps in gathering the complete information including its formation traits and fluid properties. It entails the process of lowering down some advanced and accurate measurement probes into the well for measuring the required properties. Basically, you need a winch and an electrical logging cable to insert the probes into the well. The data collected by the probe can be read on a surface logging unit.
Why Do You Need To Log A Well?
It is the cheapest method of collecting and assessing the data related to geophysical properties of a well. Instead of drilling wells with dedicated coring tools, it is much more cost-effective to obtain wireline logs using high-tech logging equipment. In the process of coring, the cores must be brought to the surface for their complete analysis. This can be tedious the pressure in the well can damage softer sediments in this core. In this regard, logging data offers better insights about the natural characteristics of sediments or rocks without causing any damage to them.
Secondly, well logging provides real-time evaluation of the formation characteristics. This information can be effectively used for correcting the borehole drilling schedules. For example, if the depth of target formation is different from the expected depth, well logs can be used for assessing this flaw and take corrective measures in the real time.
The formation of well logs takes much lesser resources as compared to coring method. They take lesser space for storage than core samples. The latter needs climate-controlled facilities for their storage. The data, once captured, can be evaluated again for further exploration of the same site for more natural resources.
The Applications of Well Logging Procedures:
There are many industries and research fields in which well logs can help in gathering accurate data. All you need is the best range of equipment available in the industry. You can easily find solutions for your particular applications in any required field. The main applications of well logs are:
• Groundwater drilling for verifying the construction of a well, maintaining the quality of water, preventing environmental losses, and complying with the regulations.
• Environmental applications of well logs include a study of borehole geophysics for remediation, monitoring of the subsurface, and compliances with environmental regulations.
• Well logs are used in mining applications for saving the money required for assessing the core characteristics. Also, it helps in reducing the downtimes and optimizing the mining sites with a focus on worker safety.
• A wide array of research organizations uses these logs for studying, measuring, and defining the properties of rocks and fluids. This helps in the progression of scientific knowledge that can resolve the major concerns of many industries.
• The energy companies also use this data for characterizing the reservoirs and improving the efficiencies.
• The geotechnical companies use well logging for studying the structural integrity of surface.
These are some of the main applications of well logs collected by high-precision and advanced equipment.
