The importance of drill stem testing can not be understated. Producers must test wells for a number of important things. First, they must ensure the wells operate at a proper level so that workers can extract oil quickly and efficiently. They also must ensure that wells are safe, not only for those working in them but for the surrounding environment.
As this blog recently covered, many felt fracking in Ohio contributed to an earthquake felt late last year. Some argue that had the area been properly tested, oilfield producers could have been better equipped to mitigate the potential dangers of their operations.
drill stem testing, when conducted properly, can reveal important information to producers who can then adjust their strategies so they do not waste their efforts in poor areas. Such was the case in Nevada, where tests of wells in Hot Creek Valley – located in the central part of the state – produced less-than-stellar results.
According to a local Nevada NBC affiliate, U.S. Oil and Gas has announced that they will conduct further testing of the area because many wells were found to contain little to no oil.
"Twenty-six of the 30 areas drilled are not expected to produce oil," said a report constructed by U.S. Oil and Gas CEO Brian McDonnell. "Two zones produced oil and water, and two zones did produce a measurable flow of oil."
The company can not accept such a limited amount of oil from their operations, so they continue to drill and conduct more tests until they are satisfied with what they are able to extract. These tests can be costly, however, so efficiency is key. Utilizing proper drill stem testing will allow producers to ensure their testing efforts are thorough without wasting an extensive amount of time and money.
