Logging Tests Offer More Precise Look at Subsurface Formations

The processes involved in oil and gas research have transformed dramatically over the course of the last two decades. At the forefront of those changes have been the introduction of advanced technology that have made it possible for producers to develop natural gas and petroleum deposits that were previously believed to be unreachable. In the early days of the oil and gas industry, the only method for locating underground deposits was to search through evidence on the surface. This resulted in a highly inefficient, expensive, and difficult exploration process. As energy demands have increased, the need for more reliable methods for locating oil and petroleum deposited has also increased.

Logging involves performing various tests during as well as after the drilling process in order to gain a more definitive picture of formations below the surface. There are actually more than 100 different types of tests that can be conducted. Standard logging often involves the examination of drill cuttings and core samples that allow geologists to examine the various layers of rock for evaluating levels of fluid content and porosity. As a result, it is possible to gain a more in-depth understanding to the subsurface structure and the viability of potential deposits.
