What is a gas condensate reservoir?

What is a gas condensate reservoir? Gas condensate reservoirs are gas systems that reside in reservoirs with the original temperatures lying between the critical temperature, TC, and the cricondentherm (Tmax in Figure 2.11). This is

What is a gas condensate reservoir?

Gas condensate reservoirs are gas systems that reside in reservoirs with the original temperatures lying between the critical temperature, TC, and the cricondentherm (Tmax in Figure 2.11). This is essentially what is occurring in the reservoir of a gas condensate system but under isothermal conditions.

What is the difference between wet gas and condensate?

A wet-gas reservoir is defined as producing a single gas composition to the producing well perforations throughout its life. Condensate will form either while flowing to the surface or in lease-separation equipment.

What is condensate in gas processing?

Gas condensate is a hydrocarbon liquid stream separated from natural gas and consists of higher-molecular-weight hydrocarbons that exist in the reservoir as constituents of natural gas but which are recovered as liquids in separators, field facilities, or gas-processing plants.

Which test is used for gas condensate?

Obtaining a representative formation fluid sample that may be used for compositional and pressure-volume-temperature (PVT) analysis is crucial in testing gas condensate reservoirs. In most cases, this means maintaining a monophasic sample as close as possible to actual reservoir conditions.

Is it favorable to have gas condensate in a reservoir?

The source rocks in second section of Nantun formation are deeply buried, the reservoir temperature is high, and hydrocarbon of hydrocarbon is higher, which is favorable for forming gas condensate reservoir..

Is condensate a gas or oil?

Condensate is a mixture of light liquid hydrocarbons, similar to a very light (high API) crude oil. It is typically separated out of a natural gas stream at the point of production (field separation) when the temperature and pressure of the gas is dropped to atmospheric conditions.

Is gas wet or dry?

When natural gas is retrieved, it can be considered wet or dry. Dry natural gas is at least 85% methane, but often more. Wet natural gas contains some methane, but also contains liquids such as ethane, propane or butane. The more methane natural gas contains, the dryer it is.

Is condensate an NGL?

In U.S. usage, a “plant condensate” is the equivalent of products classified as “pentanes+” and natural gasoline, and these are considered NGLs.

What is the difference between naphtha and condensate?

Condensate is mostly composed of NGLs and naphtha range material, and has an API from 45 to 70+. Condensate is typically valued lower than crude oil because of its high light ends content, which yields a lot of lower value LPGs and light naphtha and makes it difficult to process in high volumes in a refinery.

What is natural gas price today?

Energy

Name Price Unit
Natural Gas (Henry Hub) 4.60 USD per MMBtu
Ethanol 2.22 USD per Gallon
Heating Oil 56.00 USD per 100 Liter
Coal 168.45 USD per Ton

What is gas condensate used for?

Uses. Condensates are used as refinery feedstocks for the manufacture of products such as petrol (gasoline), jet fuel, diesel and heating fuels. Some condensates, particularly those with a high paraffin content, are used for the manufacture of ethylene.

How is pressure maintained in condensate reservoirs?

In gas-condensate reservoirs, after the liquids or condensate are recovered at the surface, the residue gas (dry gas) is returned to the reservoir to maintain pressure. This prevents retrograde condensation, which will form unrecoverable liquid hydrocarbons in the reservoir.
