Exercise chapter 1

(Oil and Gas Properties)

SECTION 01

1. Fill in the following blanks using one (or more) of the gas categories:

A. Carbon dioxide;

B. Hydrogen sulfide (H2S);

C. Inert gases (khí trơ).

_____ can form both inorganically and organically (hữu cơ).

_____ is poisonous and highly corrosive (ăn mòn).

_____ can usually be found in trace amounts (tổng số dấu vết) in hydrocarbons, but not often is there more than a trace.

_____ forms during the oxidation (quá trình oxi hóa) of organic material.

_____ is the controlling factor in classifying gas or oil as sweet or sour.

_____ is often associated with (liên kết, liên quan) evaporates (đá trầm tích do bốc hơi) within a hydrocarbon province.

_____ can only form inorganically (for example near volcanic plugs (đá phun trào bịt kín miệng núi lửa)).

2. Match each of the "Gas" terms above with its definition below by placing

the correct letter in the space provided.

A. Free Gas LPG (liquified Petroleum Gas) is comprised of heavier

hydrocarbon gases stored under pressure in a liquid

form.

B. Dissolved

Gas

Associated Gas is natural gas which overlies (che, phủ)

crude oil as a gas cap.

C.

Associated

Gas

Dry Gas is defined as mostly methane gas.

D. Dry Gas LNG (liquified natural gas) is hydrocarbon gas (usually

methane) which is compressed into liquid for storage

and transportation.

E. Wet Gas Free Gas is in a gaseous phase in the subsurface (lớp

dưới bề mặt) reservoir and remains in a gaseous

phase when produced.

F. NGL Wet Gas contains heavier hydrocarbon gases as well

as methane.

G. LPG NGL (Natural Gas Liquids) are the hydrocarbon liquids

which are separated from the produced-gas stream.

H. LNG Dissolved Gas is in solution within crude oil in the

subsurface reservoir, but bubbles out of solution when

pressure and temperature drops.
