The total flow rate of all wells in total are measured, but the contributions of the individual wells are unknown. It is important to know the individual contributions to account hydrocarbon material balance and for well monitoring and reservoir management. There are many flavours of well tests and various ways to categorize test types by its objectives, however two main categories only by objectives, these are productivity tests and descriptive tests. ...

Hydrogen sulfide is a highly flammable hazardous gas that occurs naturally in crude petroleum and natural gas. It also is present in sewage, created through the breakdown of organic matter, and can cause negative health effects when inhaled. Hydrogen sulfide is heavier than air so it tends to be more highly concentrated in low-lying areas that are poorly ventilated, such as basements, manholes, sewer lines, and underground telephone or electrical vaults. ...

2019 witnessed discovering several oil and gas fields in many countries around the world, will be granted economic and political importance and reflective of some conflicts in these countries.

At the gas plant, initial steps remove any remaining particulate matter and further reduce the water-vapor content of the incoming gas. Then, focus turns to the separation of hydrocarbons and fluids to yield pipelinequality dry natural gas. Whether naturally occurring in gas reservoirs or resulting from injection into the gas cap for pressure maintenance, nitrogen is frequently present in natural gas at levels that decrease its quality and restrict its  marketability. ...
