In-Situ Combustion (ISC), also known as fireflooding, is a thermal enhanced oil recovery (EOR) method that generates heat within the reservoir by igniting a portion…

Steam-Assisted Gravity Drainage (SAGD) is an advanced enhanced oil recovery (EOR) technique specifically designed to extract heavy crude oil and bitumen from deep, unconsolidated reservoirs…

Cyclic Steam Stimulation (CSS), also widely known as the “huff and puff” method, is a mature thermal enhanced oil recovery (EOR) technique primarily applied to…

Steam injection is a thermal enhanced oil recovery (EOR) method that introduces high-temperature steam into a reservoir to reduce oil viscosity, improve mobility, and displace…

Alkaline Flooding (also known as caustic flooding or alkaline waterflooding) is a chemical enhanced oil recovery (EOR) method in which a high-pH solution—typically sodium hydroxide…

Surfactant Flooding is an enhanced oil recovery (EOR) technique in which a dilute solution of surface-active agents (surfactants) is injected into a reservoir to mobilize…

Polymer flooding is a chemical enhanced oil recovery (EOR) method used to improve the efficiency of waterflooding in oil reservoirs. By adding small amounts of…
