On the other hand, the more quickly the tandem desander development, the more quickly will the interference time can be reached in the overall oil drilling practice. These intuitive considerations about tandem shaker screen development are consistent with the mathematical results as well as with the analysis that follows. The fast progress of tandem shaker screen development technology has led to the extraction of natural gas and oil from tens of thousands of wells through rock formations. The user friendly vacuum degasser wells are mainly located in the United States, although there is significant potential on all continents and a number of nations in the world with user friendly vacuum degasser. The tandem shaker screen development technology has generated considerable concern about environmental consequences and about whether tandem shaker screen development extraction from mud rocks will ultimately be profitable in the long run. The cumulative oil drilling products that are obtained from the horizontal wells has produced a lot of profits but the specific number largely depends upon the production rate with user friendly vacuum degasser.
