The Role of Core Samples in Determining the Profitability of a Well
The amount of oil and natural gas that can be recovered from a particular reservoir is determined by both rock and fluid properties. Following the drilling of an exploratory well, the well is evaluated to determine whether there are sufficient amounts of natural gas and oil in the reservoir to make it financially practical to begin recovery operations. Drilling mud is typically run through a special sieve as it is brought to the surface. Drill cuttings can then be removed and small portions of rock selected to. This type of oil and gas research provides a wealth of information, including the type of rock that is being drilled and how porous the rock is. This research can also determine whether oil is present in the reservoir.
