Oil and gas well terminology

The following are abbreviations and definitions of terms commonly used in the oil and gas industry and this website. One barrel of crude oil or NGL or 42 gallons of liquid volume. One billion cubic feet of natural gas volume. One billion cubic feet of natural gas equivalent. Glossary of Oilfield Production Terminology (GOT) (DEFINITIONS AND ABBREVIATIONS) This Glossary was adapted from several sources. It includes several terms for which there is no Corrosion of Oil and Gas-Well Equipment (COGWE), 1958 Subsurface Salt Water Injection and Disposal (SSWID), Second Edition Tests in an oil or gas well are carried out to determine its flow capacity at specific conditions of reservoir and flowing pressures. Important concepts, such as absolute open flow potential, annular pressure, critical flow rate, net gas production and water/oil ratio are covered in this discipline.

Annulus: the annular space in a well between the “drill string” or drilling string or production tubing and the well bore or casing. Anticline: a fold in layered rocks  from which groundwater can be extracted using a water well. Barrel of oil equivalent (BOE). • A measure used to aggregate oil and gas resources or production,  Gas produced with oil in oil wells. The gas is taken from the well through the casinghead at the top of the well. Catalytic Cracking. A refining process  9 Nov 2019 Active Well: A well that is currently producing oil or natural gas. API Gravity: A measure of the relative density of a petroleum liquid. A well drilled as part of an appraisal drilling programme which is carried out to determine the physical extent, reserves and likely production rate of a field.

n: in well cementing, the fluid, usually drilling mud or salt water, that is pumped into the well after the cement is pumped into it to force the cement out of the casing and into the annulus. dissolved gas n: natural gas that is in solution with crude oil in the reservoir. dissolved-gas drive

Appraisal Well: Well drilled after the discovery of oil or gas to establish the limits of the reservoir, the productivity of wells in it and the properties of the oil or gas.

14 Oct 2016 The two- to three-day process of hydraulic fracturing for oil and gas is perhaps one of to enable safe and efficient production from an oil or gas well. Middle East in terms of long-term resources and energy independence.

The costs associated with abandoning a well or production facility are referred to as the “Abandoning Costs,” which costs typically cover the plugging of wells;  3 Mar 2016 In the early days of the oil industry, drilling wells was a simple operation. horizontal wells may be less prone to water or gas coning behavior. Casing – Pipe cemented in an oil or gas well to seal off formation fluids and to keep the borehole from caving in. Smaller diameter “strings” of casing are
