The pressure gradient of a column of fresh water is approximately
0.433 psi/ft. -
correct answer ✅True
If our drilling fluid pressure was substantially greater than the
formation pressure, the deep induction curve would have little
value to a well logging engineer, as he/she would not be able to
measure Rt. -
correct answer ✅True
What lithology tool can be used by the engineer to view a reservoir
sand, for the purpose of perforations? -
correct answer ✅GR (Gamma Radiation)
The lithology tool that measures the natural potential that is
created, as a result of co-mingling of drilling fluids with reservoir
fluids is a _________________ tool -
correct answer ✅SP (Spontaneous Potential)
Drillers use ______________ tools, as a qualitative measure, to

You are drilling a well, using a water-base mud ,into a Louisiana gulf
coast formation, at 18,000 feet (TVD). If the formation was over-
pressured by 1,500 psi, what mud-weight would you need to equal
formation pressure? -
correct answer ✅10.54 ppg
There are 43,560 sq. ft., in an acre. Your friend wants you to invest
in a newly discovered oil field where the reservoir extends
approximately 65 acres of land. The top of the reservoir is located
at 12,000 ft. (TVD) and the bottom of the productive zone is located
at 12, 025 ft. (TVD). From the sonic log delta-t reads 90 usec/ft.,
and from the electric log the deep induction curve reads 0.27 ohms
in a 100% wet sandstone that has no shale or other rocks/minerals
in it, and the deep induction curve reads 3.0 ohms in the zone of
interest (target zone). The formation recovery factor is 65% and Bo
is equal to 1.4. The amount of OOIP and STB is equal to
_____________/____________. -

mud? -
correct answer ✅8.00 ppg
If you were drilling a well into a normally pressured south Louisiana
formation, and your drill bit is at the bottom of a 196 stand string of
drill-pipe and drill-collars, what mud-weight would you need to
equal formation pressure? -
correct answer ✅8.94 ppg
_____________ logging consists of irradiating the wall of a
borehole with Gamma Rays and studying the effect of their
