Liquefied Natural Gas (LNG) is natural gas that has been cooled to approximately -162°C (-260°F) at atmospheric pressure, transforming it into a clear, colorless, and…

An injection well is a well drilled and completed specifically to introduce fluids or gases into subsurface geological formations for purposes related to oil and…

A frac hit (also known as frac communication or well interference) is an unintended pressure and fluid connection between a newly stimulated well (the child…

Flow assurance is a critical discipline in oil and gas production and operations that ensures the safe, reliable, and uninterrupted transport of hydrocarbons—liquids, gases, and…

Fishing is the specialized oilfield operation of retrieving lost or stuck equipment, tools, or debris from a wellbore. It is a critical remedial activity in…

Drilling fluid, commonly called drilling mud, is a specialized fluid circulated through the wellbore during drilling operations. It is essential for safe and efficient well…

Formation damage is the reduction of natural permeability and porosity in the reservoir rock near the wellbore, caused by intrusive operations such as drilling, completion,…

A kick is an unplanned influx of formation fluids (oil, gas, or water) into the wellbore during drilling, completion, workover, or production operations. It occurs…

Gas Lift is an artificial lift method used in oil and gas production to increase the flow of reservoir fluids (oil, water, and gas) from…

Dewatering in oil and gas production refers to the process of removing water from produced hydrocarbon fluids (crude oil, natural gas, or condensate) to meet…

Coring is a fundamental sampling technique used in the oil and gas industry to retrieve a cylindrical section of subsurface rock formation for direct physical…

Completion refers to the series of processes and equipment installed in a well after drilling has finished, enabling the safe, controlled, and efficient flow of…
