What is the drill test?

Sometimes known as DST, the drilling trunk test is a type of structured evaluation that allows you to determine the make -up geological formation located with a bore tube inserted into the ground during natural gas or oil extraction. In many cases, this type of test can help determine whether drilling in this area is likely to bring the desired results or whether the search for another site would be more fruitful. It is also possible to use a drill test to determine whether a place is suitable for digging water, oil or natural gas.

first developed in the second part of the 20th century, the actual device used in the test of the drill trunk has evolved over time. Previous methods included the use of a small charge to create perforation in a plastic case, which was reduced through the drill stem. When the charge was ignited, it created a small perforation in a housing that made it possible to collect samples of surrounding fluids or earth. The sample has been loaded and examined. In recent years, the STEM test for drill has used technoThe logi that allows you to operate small robots through the drill bit, collect the sample and provide immediate feedback on the sample composition.

The results of the drilling trunk test allow you to determine which places are likely to bring enough product to make it commercially viable. By examining the sample taken from the test, it is possible to calculate the concentration of natural gas or oil that can be exempted adequately. If the test results indicate that the amount of product available falls below a certain range, the site is abandoned and other tested areas. The same general director applies when using a drilling trunk test to search for water. If the sample does not show the presence of fair amounts of water at a certain distance from the surface, the place is abandoned in favor of another that is likely to provide sufficient water supply.

Depending on the type of device used to perform a drilling trunk test, the process may take up to 24DIN before the results are considered final. This is especially true if it is also necessary to carry out values ​​that indicate the level of pressure on the spot together with the availability of the product required for extraction and possible sale. Since tests of this type often include volatile materials, security measures that help minimize the danger to the borehole staff are common, with many nations stipulating specific regulations regarding the types of preventive measures that must be used during testing.
