p.s.i.a. | Abbreviation for Pounds per Square Inch Absolute.Ê Absolute pressure is the sum of Atmospheric Pressure plus Gauge Pressure. |
Pentane, Normal | See Normal Pentane. |
Pentanes Plus | A hydrocarbon mixture consisting mostly of normal pentane and heavier components. |
Pipeline Balancing | The process of matching a gas nomination with actual flow. The goal is to avoid pipeline pentalties for under or over producing by borrowing or purchasing gas from or lending or selling gas to other producers or gatherers. |
Pipeline Condensate | Liquid hydrocarbons that have condensed from gas to liquid as a result of changes in pressure and temperature as gas flows in a pipeline.Ê Pipeline condensate only remains as a liquid under high-pressure conditions and would vaporize at atmospheric pressure. |
Pipeline Fill | The amount or inventory of hydrocarbons in a pipeline between the receipt and delivery points in a gathering system. Also called Line Fill. |
Pipeline Pig | The tool inserted into a pipeline that travels the length of the pipeline pushed by hydrocarbon flow, used to remove liquids or other objects which could obstruct flow.. |
Plant Products | All liquid hydrocarbons and other products (including sulfur and excluding residue gas) recovered in a gas processing plant. |
Pressure Base | The contractual, regulatory or standard ambient pressure at which natural gas is measured or sampled expressed in psia (pounds per square inch absolute). |
Producer Balancing | Paying a gas royalty owner based on actual production or entitlement and reconciling and settling the delta. |
Propane | A normally gaseous paraffin compound having the chemical formula of C3H8. |
