Note that reservoir barrels undergo shrinkage by the reservoir volume factor as gas escapes. Stock tank barrels are measured after gas escapes.

Jan 24, 2018 ยท January 24, 2018 by Jessica Summers (Bloomberg) Crude popped above $65 a barrel for the first time in more than three years after U.S. crude stockpiles fell for a 10th week in the longest stretch of declines on record. The difference in height between the static level and the dynamic level in a pumping well, expressed as hydrostatic fluid pressure. The drawdown, and therefore the production rate, of a producing interval is typically controlled by surface chokes. Reservoir conditions, such as the tendency to produce sand, may limit the drawdown that may be safely applied during production before damage or unwanted sand production occurs.

Water coning Definition. Advertisement. Water coning: The upward encroachment of water into a well caused by pressure drawdown from production. Pages in category "Oilfield Glossary" The following 8 pages are in this category, out of 8 total. The productivity index is a measure of the well potential or ability to produce and is a commonly measured well property 1.The symbol J is commonly used to express the productivity index; as well as, being the preferred symbol by the Society of Petroleum Engineers.

Reservoir pressure definition: The average pressure within the reservoir at any given time. Determination of this value is best made by bottomhole pressure measurements with adequate Oilfield Glossary | Oil and Gas Glossary In UBD, we select a fluid that provides a hydrostatic pressure of around 200 psi below the initial reservoir pressure. This provides a good starting point for the selection of a fluid system. During the feasibility study, this drawdown is normally further refined, depending on the expected reservoir inflow and other drilling parameters. The difference in height between the static level and the dynamic level in a pumping well, expressed as hydrostatic fluid pressure. In water-related science and engineering, there are two similar but distinct definitions in use for the word drawdown: . In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. Wellbore: A borehole; the hole drilled by the bit. A wellbore may have casing in it or it may be open (uncased); or part of it may be cased, and part of it may be open. Also called a borehole or hole.

In the oil and gas industry, the difference between the average reservoir pressure and the wellbore bottom flowing pressure in a producing well is called the drawdown. Depleted storage field: A sub-surface natural geological reservoir, usually a depleted gas or oil field, used for storing natural gas. Depletion (coal): The subtraction of both tonnage produced and the tonnage lost to mining from identified resources to determine the remaining tonnage as of a certain time.

Oil field An accumulation, pool or group of pools of oil in the subsurface, containing producible oil. An oil field consists of a reservoir in a shape that will trap hydrocarbons and that is covered by an impermeable or sealing rock. It may also contain associated gas. Operator

In UBD, we select a fluid that provides a hydrostatic pressure of around 200 psi below the initial reservoir pressure. This provides a good starting point for the selection of a fluid system. During the feasibility study, this drawdown is normally further refined, depending on the expected reservoir inflow and other drilling parameters.

A cast-iron or magnesium drillable tool consisting of a packing assembly and a back-pressure valve. It is used to close off the annular space between tubing or drill pipe and casing to allow the placement of cement or fluid through the tubing or drill pipe at any predetermined point behind the casing or liner, around the shoe, or into the open hole around the shoe.
