Production & Operations

Artificial lift is a broad category of production engineering techniques used to increase the flow of hydrocarbons (oil, gas, and water) from a reservoir to…

Bottomhole pressure (BHP) is the pressure measured at the bottom of a wellbore, usually at the midpoint of the producing interval or at the depth…

Casing is a large-diameter pipe that is run into a wellbore and cemented in place to provide structural integrity, isolate formations, and enable safe and…

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…

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…

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…

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…

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…

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…

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

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…
