Thermal Damping of Temperature Probes: Monitoring …

2019-4-24 · We receive a lot of questions on the use of thermal damping devices for temperature sensors. Mostly it depends on your appliion, but for mapping studies we usually advise against damping the measurements. This is because almost every controlled environment that needs to be qualified provides a stable environment for the stored item by bathing it in temperature-controlled air.

Global Mitigation On Non-CO2 Greenhouse Gases

The non-CO2 gases include CH4, N2O, and a nuer of high global warming potential or fluorinated gases. The non-CO2 greenhouse gases are more potent than CO2 (per unit weight) at trapping heat within the atmosphere and, once emitted, can remain in the atmosphere for either shorter or longer periods of time than CO2. The GWP of SF6 is 23,900

Non-Radioactive Tracing of Injection Gas in Reservoirs

A WAG pilot was started in spring 1991. To improve evaluation of the pilot it was decided to inject tracers in the gas phase early in the first two gas injection periods. Production from the Sleipner field was started in August 1993. Reinjection of gas started in April 1994 and …

Glossary | S&P Global Platts

The UK''s flexibility mechanism, also known as the flex, is operated by Transco (British Gas) to make sure the amount of gas in the pipeline remains more or less constant at all times. If the system goes out of balance, Transco uses the flex to balance the system by buying and selling gas based on bids and offers submitted by shippers.
