Technology of hydraulic fracturing as well as the practice of drilling horizontal wells underground are both well-established methods with a long history. It is no surprise that the use of hydraulic fracturing has proven to be one of the most effective methods of extracting oil and gas from both horizontal and vertical wells. This method differs from the conventional oil and gas production because hydraulic stimulation takes place in the well. When hydraulic stimulation is employed to extract carbohydrates from a reservoir, it is known as an unconventional production method.
Hydraulic fracturing is conducted by pumping hydraulic fluid directly into the wellbore. The high‑volume fracking method requires more fracking fluid compared to the low‑volume fracking method. Hydraulic fluid is largely composed of water, a small proportion of proppant and a very small proportion of chemicals. The hydraulic fluid, along with the high pressures generated, increases the permeability of the rock surrounding the borehole, creating fractures that allow the release of the carbohydrates trapped in the reservoir due to reservoir’s low or nonexistent permeability to the surface.
With the help of publicly available data, I have been able to present some of the carbohydrate resources in the Petišovci-globoko area (northeastern part of Slovenia) and the increased gas production observed after the hydraulic fracturing method was conducted in the said area.
