23/11/2014, · As fresh oil has flowed, so have new jobs. Hydraulic ,fracturing, – or “fracking,” as it is often referred to – is the process of drilling deep beneath the earth’s surface to crack, or fracture, rock formations to access oil and natural gas deposits. The process is not new, but advancements in technology spurred a recent boom and vaulted the United States to No. 1 status among the ...

As natural gas production has shifted further from deep prolific gas reservoirs to shale gas, several questions are being addressed regarding ,fracturing, technologies and the fate of chemical additives. A less investigated issue is the unexpected increase in produced hydrogen sulfide (H2S) from hot shale gas reservoirs. Understanding the source of H2S in shale reservoirs and managing low-levels ...

This causes the invaded hydraulic-,fracturing fluid, to be trapped in small pores within the matrix and accumulate near the hydraulic fracture. The profile of liquid saturation in the figure shows the overall blockage caused by both aqueous and condensate phases that leads to a significant reduction in the gas relative permeability near the fracture (Fig. 1b).
