What is the volumetric method?
Volumetric analysis, any method of quantitative chemical analysis in which the amount of a substance is determined by measuring the volume that it occupies or, in broader usage, the volume of a second substance that combines with the first in known proportions, more correctly called titrimetric analysis (see titration) …
How many circulations are required in volumetric method of well control?
two circulations
The Driller’s Method requires two circulations. During the first circulation, the influx is circulated out with the original mud weight. Constant BHP is maintained by holding circulating drill pipe pressure constant through the first circulation.
What is the unit of Stoiip?
STOIIP = 902.1 MM STB. Reserves. In reservoir engineering, volume of hydrocarbon in a reservoir called volume in place (oil and/or gas). Volume of hydrocarbon that can be commercially recovered is called “Reserves”.
What is the basic principle of volumetric analysis?
The basic principle of Volumetric analysis: The solution which we want to analyze contains a chemical of unknown amount then the reagent reacts with that chemical of unknown amount in the presence of an indicator to show the end-point. End-point shows that the reaction is complete.
What is the principle of volumetric titration?
Volumetric Analysis Titration in Chemistry. The analytical method wherein the concentration of a substance in a solution is estimated by adding exactly the same number of equivalents of another substance present in a solution of known concentration is called volumetric analysis. This is the basic principle of titration …
How do you control a kick?
Well-control procedures
- One-Circulation, or Wait-and-Weight, Method. After the kick is shut in, weight the mud to kill density and then pump out the kick fluid in one circulation using the kill mud.
- Two-Circulation, or Driller’s, Method.
- Concurrent Method.
What is kick in drilling?
A kick is a well control problem in which the pressure found within the drilled rock is higher than the mud hydrostatic pressure acting on the borehole or rock face. When this occurs, the greater formation pressure has a tendency to force formation fluids into the wellbore. This forced fluid flow is called a kick.
How is Oiip calculated?
Calculating OIIP requires engineers to determine how porous the rock surrounding the oil is, how high water saturation might be and the net rock volume of the reservoir. The numbers for the aforementioned factors are established by conducting a series of test drills around the reservoir.
What does Mmbo mean?
Definition. MMBO. Million barrels of oil .
How do you calculate recovery factor?
Recovery factor (RF) = over all proportion of oil expected to be recovered from the reservoir = production + proven and probably reserves/ Stock Tank Oil Initially In Place (STOIIP) or Oil Originally In Place (OOIP). RF = RFp + RFs + EOR + proven and probably reserves.
How is the volumetric method used in petroleum engineering?
The Volumetric Method The volumetric equation is useful in reserve work for estimating gas in place at any stage of depletion. During the development period before reservoir limits have been accurately defined, it is convenient to calculate gas in place per acre-foot of bulk reservoir rock.
When do you use a volumetric well control?
The volumetric method is mostly used in workover and production operations. It is a means of allowing the gas to migrate to surface under control. The gas needs to migrate at over (approx.) 1000′ per hour. To allow the bubble to expand the casing pressure is held constant for a given volume of mud bled off.
What can volumetric technologies do for your business?
For over 25 years, we’ve helped customers in a variety of industries increase their productivity and decrease costs by providing reliable filling machines and equipment that boost the efficiency and accuracy of their production lines. Accuracy, speed, and precision — these are qualities you can expect from Volumetric Technologies.
When to use volumetric method to calculate gas in place?
Later in the life of the reservoir, when the reservoir volume is defined and Performance data are available, volumetric calculations provide valuable checks on gas in place estimates obtained from material balance methods. The equation for calculating gas in place is: Bgi = gas formation volume factor, ft3/scf.
