Assessing the feasibility of enzyme technology for the biodegradation of polymers used in hydraulic fracturing operations

碳氢化合物，如天然气中的甲烷、乙烷和丙烷，是从地下深处的储层中开采出来的。在某些情况下，可以通过在储层中钻一系列威尔斯井来相对容易地获取烃。碳氢化合物很容易从储层移动到收集它们的威尔斯井中。这些被称为常规储层。然而，在某些情况下，气体不容易移动到井中，因此简单地钻井是不够的。这些非常规油气藏需要更多的工作来回收碳氢化合物。已经采取的一种释放碳氢化合物的方法被称为水力压裂。在这种方法中，液体在高压下被泵入井中并进入储集岩，使其破裂。以这种方式压裂储层有利于烃的移动。一旦

Hydrocarbons, such as the methane, ethane and propane found in natural gas, are recovered from reservoirs deep under the ground. In some cases, the hydrocarbon can be accessed relatively easily by drilling a series of wells into a reservoir. The hydrocarbons readily move from the reservoir into the wells where they are collected. These are known as conventional reservoirs. However, in some cases the gas does not easily move into a well, and thus simply drilling the well is not sufficient. These unconventional reservoirs require more work to recover the hydrocarbons. One approach that has been taken to free the hydrocarbons is called hydraulic fracturing. In this approach, liquids are pumped at high pressure down a well and into the reservoir rock causing it to crack. Fracturing the reservoir in this manner facilitates the movement of hydrocarbons.
