SECONDARY RECOVERY Meaning and
Definition
-
Secondary recovery refers to a method of oil and gas extraction employed in the petroleum industry. It is a process utilized to extract additional hydrocarbons that remain in a reservoir following the primary recovery stage. The primary recovery method typically involves the natural pressure present within the reservoir to bring oil and gas to the surface. However, primary recovery methods often leave behind a substantial portion of the petroleum reserves.
Secondary recovery aims to enhance the recovery of oil and gas by implementing various techniques. One common technique is water injection, where water is injected into the reservoir to increase pressure and displace the remaining hydrocarbons towards the production wells. This process helps reduce the oil's viscosity and acts as a driving force to push the oil towards extraction points.
Other secondary recovery methods include gas injection, polymer flooding, and chemical flooding. Gas injection involves injecting gases like nitrogen or carbon dioxide into the reservoir to enhance pressure and displace the remaining oil. Polymer flooding refers to injecting polymers into the reservoir to increase the oil's viscosity, improving its mobility and aiding its extraction. Chemical flooding involves injecting surfactants or chemicals into the reservoir to alter interfacial tension and improve oil mobility.
Secondary recovery methods are employed when primary recovery methods become less effective or when the reservoir has a substantial amount of oil and gas remaining. These techniques can significantly increase the amount of recoverable hydrocarbon resources, helping extract more oil and gas from mature fields and maximizing resources for commercial use.

Etymology of SECONDARY RECOVERY
The etymology of the term "secondary recovery" can be understood by examining the origins of each constituent word.
1. Secondary: The word "secondary" comes from the Latin word "secundarius", which means "following" or "subsequent". It is derived from the Latin word "secundus", meaning "second" or "favorable". Over time, "secondary" developed its modern usage to refer to something that is of lesser importance or comes after something else.
2. Recovery: The term "recovery" traces its roots back to the Latin word "recuperare", meaning "to regain" or "reclaim". It is a combination of the prefix "re-" (meaning "again" or "back") and "capere" (meaning "to take"). "Recovery", in its general sense, refers to the process of regaining possession or returning to a normal state after a setback or illness.
