Effect of Water Blocking Damage on Flow Efficiency and Productivity in Tight Gas Reservoirs

Abstract: Tight gas reservoirs normally have production problems due to very low matrix permeability and significant damage during well drilling, completion, stimulation and production. Therefore, they might not flow gas at optimum rates without advanced production improvement techniques. The main damage mechanisms and the factors that have significant influence on total skin factor in tight gas reservoirs include mechanical damage to formation rock, water blocking, relative permeability reduction around … Show more

“…Therefore, hydraulic fracturing is commonly used to stimulate wells in coal seam, shale and tight gas reservoirs (Wang et al, 2012). For reservoirs with very low permeability, fracturing and drilling fluid leak-off along with capillary end effect leads to an increase of water saturation in the near wellbore or fracture-wall regions (Xie et al, 2009;Bahrami et al, 2011;Odumabo et al, 2014). Fluid invasion into the reservoir is greatly affected by the contact angle (Li et al, 2014).…”

“…This water entrapment is referred to as water blockage. A few studies have been conducted on water block clean-up (Mahadevan et al, 2007(Mahadevan et al, , 2009 and the long-term effects on production (Bahrami et al, 2011). One of the most effective methods to reduce water retention is wettability alteration (Barenblatt et al, 1990).…”

“…However, in such reservoirs with naturally low permeability, the capillary effect is significant if compared to the viscous effect. The capillary end effect as well as loss of fracturing and drilling fluids will lead to an increase of water saturation near the wellbore or fracture faces (Xie et al, 2009;Bahrami et al, 2011;Odumabo et al, 2014). Fluid invasion and water saturation in wellbore vicinity are sensitive to the contact angle of rock surface (Li et al, 2014).…”

“…Tight gas reservoirs are susceptible to formation damages such as phase trapping and clay swelling due to small pore diameter, which is less than micron in average (Bahrami et al, 2011). Phase trapping is consequence of interaction of capillary pressure and relative permeability phenomena in formation(D. Bennion, Thomas, Schulmeister, & Romanova, 2006).…”
