What is a common method to increase production in a low-permeability reservoir?

• A. Water Flooding
• B. Gas Lift
• C. Hydraulic Fracturing
• D. Steam Injection

Answer: (C)

In tight, low-permeability rocks, fluids can’t flow quickly because the natural pathways are few and narrow. To boost production, you need to create new, conductive channels from the wellbore into the reservoir. Hydraulic fracturing does just that by injecting fluid at high pressure to crack the rock, forming fractures that dramatically increase the surface area and connect more of the reservoir to the well. The fractures are kept open with proppant, so even after the pressure drops, the pathways stay, allowing higher production rates and better recovery from such formations. Water flooding aims to push oil through the rock but is often ineffective in very tight rocks because the flow paths aren’t well connected. Gas lift helps bring fluids to the surface but doesn’t improve the rock’s connectivity. Steam injection is a thermal method used primarily for heavy oil to reduce viscosity, not for creating new flow channels in low-perm formations.
