volume at the end of the compression process is called? Compression ratio
68. What is gravity drainage is? The least common primary recovery mechanism in
which the force of gravity pushes hydrocarbons out of the reservoir, into the
wellbore and up to surface.
69. Natural gas that contains less methane (typically less than 85% methane) and more
ethane and other more complex hydrocarbons is called? Wet gas
70. A device for measuring the internal diameter of a casing, tubing or open borehole using
high-frequency acoustic signals, is called? Ultrasonic Caliper
71. This is a device for measuring in situ the velocity of fluid flow in a production or
injection well in which a packer is inflated between the tool housing and the casing
wall, causing the total fluid flow to pass inside the tool and over a spinner. What is
device called? Packer flowmeter
72. What is the definition of kick? physically caused by the pressure in the wellbore
being less than that of the formation fluids, thus causing flow.
73. The working platform approximately halfway up the derrick or mast in which the
derrickman stores drillpipe and drill collars in an orderly fashion during trips out of the
hole is called? Fingerboard
74. Mention two kinds of injection pattern which are used for pilot testing purposes? two-
spot and three-spot patterns.
75. What is a mechanical device used downhole to deliver an impact load to another
downhole component, especially when that component is stuck? Jar
76. What is TAPS stands for? Trans-Alaska Pipeline System 77. Mention 4 types of offshore rig! Swamp barge, Jack-up, Semi-sub, Drillship, Jacket
with tender, Fixed Platform.
78. The amount of time a liquid stays in a vessel is called? Retention time
79. It is a generic term for soft, sticky, swelling clay formations that are frequently
encountered in surface holes offshore or in sedimentary basins onshore near seas. This
clay fouls drilling tools and plugs piping, both severe problems for drilling crews.
What is this called? Gumbo
80. A chemical added to an acid to stabilize iron. The injected acid dissolves iron from
rust, millscale, iron scales or iron-containing minerals in the formation. If the iron is
not controlled, it will precipitate insoluble products such as ferric hydroxide and, in

sour environments, ferrous sulfide [FeS], which will damage the formation. What is
this chemical called? Reducing agent
81. A substance used in a gas-dehydration unit to remove water and moisture is called?
Dessicant
82. Mention 3 types of Casing!
Conductor/ stovepipe, surface casing, intermediate casing, production casing,
production liner.
83. A device that removes water and water vapor from a gas stream using two or more
beds of solid desiccants, such as silica gel or calcium chloride [CaCl2] is called? Dry-
bed dehydrator
84. A method of producing a radioactive-tracer log, in which a slug of radioactive material
is injected into the flow stream of a production or injection well from one section of a
logging tool and observed as it passes one or more gamma ray detectors in another
section, is called? Velocity-shot Measurement
85. Mention 5 types of EOR injection pattern! direct line drive, staggered line drive,
two-spot, three-spot, four-spot, five-spot, seven-spot and nine-spot
86. A check valve that has a spring-loaded plate that may be pumped through, generally in
the downhole direction, but closes if the fluid attempts to flow back through the

called? Desander
89. Mention 5 the most common reasons for running casing in a well!
1) protect fresh-water aquifers (surface casing)
2) provide strength for installation of wellhead equipment, including BOP
3) provide pressure integrity so that wellhead equipment, including BOPs, may be
close
4) seal off leaky or fractured formations into which drilling fluids are lost
5) seal off low-strength formations so that higher strength (and generally higher
pressure) formations may be penetrated safel
6) seal off high-pressure zones so that lower pressure formations may be drilled
with lower drilling fluid densities
7) seal off troublesome formations, such as flowing salt
8) comply with regulatory requirements (usually related to one of the factors
listed above).
