What is DFIT analysis?
A DFIT is a diagnostic fracture-injection/falloff test. It consists of the injection of a small volume of water or gas at a rate sufficient to create and propagate a hydraulic fracture.
How does a DFIT work?
In a diagnostic fracture injection test (DFIT), a relatively small volume of fluid is injected into the subsurface, creating a hydraulic fracture. After the end of injection, the pressure in the wellbore is monitored for hours or days.
What is Mini frac?
A minifrac test is an injection-falloff diagnostic test performed without proppant before a main fracture stimulation treatment. The intent is to break down the formation to create a short fracture during the injection period, and then to observe closure of the fracture system during the ensuing falloff period.
What does DFIT stand for?
Acronym. Definition. DFIT. Differential Functioning of Items and Tests (psychometrics)
How do you do DFIT?
In DFIT, a small fracture is created by injecting few barrels of completion fluid until formation breaks down and a fracture is initiated and propagates a short distance into the reservoir. Then, injection is stopped and the pressure decline (or falloff) is monitored.
What is an injection test in Frac?
Introduction. Diagnostic fracture injection tests (DFITs) are small pump-in treatments performed to gather data to help design follow-up hydraulic-fracturing treatments, as well as to characterize the subject reservoir.
What is hydraulic stimulation?
Hydraulic stimulation can be described as injection of fluids at high flow rates into a reservoir to develop new fractures or reactivate and enhance the hydraulic performance of existing fractures. The basic concept of hydraulic stimulation includes different failure processes of fracture initiation and propagation.
What is TAV in front office?
TAV. Timestamp-interval Adjustment at Validation.
Is Fit short for fitness?
What is the abbreviation for Fitness? (also F or fit.)
What is secondary injection test?
What is secondary injection testing? Secondary injection testing involves simulating overload and fault level magnitude currents on the current transformer’s secondary side to verify the trip characteristics, trip actuator, and latch mechanism.
What is accumulator pressure?
Accumulator is a pressure vessel for storing hydraulic pressure in it utilizing compressible and decompressible nature of nitrogen gas. So, it can be said that the accumulator has a similar function to the rechargeable electrical battery. In electricity, electrical energy is stored to the battery.
What is Surgi Frac?
Utilizing Hydra-Jet™ TS abrasive jetting tools, the SurgiFrac process involves cutting a new perforation or channel in the target interval, then moving straight into the stimulation phase, jetting the treatment fluid directly into the desired zone.
What is DFIT in hotel industry?
DFIT = Domestic Free Individual Traveller.
What does it mean when a guy calls a girl fit?
#9. Best to get the guys’ take on this but ‘fit’ seems to mean a girl a guy loves looking at like eyecandy and would love to have sex with. Beautiful suggests more that the guy is in awe of her looks and not just her body, and in some cases also her personality.
What is the difference between primary and secondary injection testing?
A primary injection test set injects a multiple of the fault rated current of the breaker, through the breaker while measuring the trip time. The secondary injection test injects a ratio of the fault rated current of the breaker directly into the trip unit and measures how long it takes the breaker to trip.
What is the Hipot test?
The hipot test, derived from the term High Potential Test, is a direct application of a high voltage to a unit under test. The test voltage is usually much higher than the usual operating voltage in order to stress the dielectric properties of the device under test.
Why accumulators are used?
They are used to maintain pressure, store and recapture energy, reduce pressure peaks, power chassis suspensions, and dampen shock, vibration and pulsations. Under gas pressure, accumulators store a volume of fluid that can be re-fed into the hydraulic system when it is needed.
