Pete 1010 Topics 13 & 14 Exam
Questions & Answers (Grade A+)
Multiple Completion -
correct answer ✅An arrangement for producing a well in which
one wellbore penetrates two or more petroleum-bearing
formations that lie one over the other. The tubing strings are
suspended side by side in the production casing string, each a
different length and each packed off to prevent the commingling of
different reservoir fluids. Each reservoir is then produced through
its own tubing string. Alternatively, a small diameter production
casing string might be provided for each reservoir as in a multiple
miniaturized or multiple tubingless completion.
Formation Fracturing -
correct answer ✅a method of stimulating production by increasing
the permeability of the producing formation. Under extremely high
hydraulic pressure, a fluid (such as water, oil, alcohol, dilute
hydrochloric acid, liquefied petroleum gas, or foam) is pumped
downward through tubing or drill pipe and forced into the
perforations in the casing. The fluid enters the formation and
breaks it. Propping agents or proppants, such as sand grains,
aluminum pellets, glass beads, or similar materials are carried in
suspension by the fluid into the cracks or fractures. When the
pressure is released at the surface, the fracturing fluid returns to
the well and the fractures partially close on the proppants, leaving
channels for oil to flow through to the well. This process is often
called a frac job.

Questions & Answers (Grade A+)
Acidizing -
correct answer ✅Treating oil-bearing limestone or other
formations with acid for the purpose of increasing production.
Hydrochloric or other acid is injected into the formation under
pressure. The acid etches the rock enlarging the pore spaces and
passages through which the reservoir fluids flow. The acid is held
under pressure for a period of time and then pumped out, after
which the well is swabbed and put back into production. Chemical
inhibitors combine with the acid to prevent corrosion of the pipe.
Wellhead -
correct answer ✅The equipment installed at the surface of the
wellbore. this includes such equipment as the casinghead and
tubing head.
Casinghead -
correct answer ✅Heavy, flanged steel fittings connected to the
first string of casing; they provide a housing for slips and packing
assemblies, allow suspension of intermediate and production
strings of casing, and supply the means for the annulus to be sealed
off.
