What is a pump card?
The pump card is a plot of the calculated loads on the pump plunger at various positions throughout its stroke. This is the plunger load that is applied to the pump valve rod or the bottom of the sucker rod string. The pump card shows that the down-stroke portion of the pump plunger card is near zero.
What is a Dyna card?
The pump dyna- graph card accurately describes the down-hole pumping conditions, Intermediate sucker rod stresses are also gen- erated by the program. In essence, through the use of mathematical solution of the sucker rod pumping sys- tem, the measured surface loaus are decoded to deter- mine the down-hole loads.
What does the downhole card represent?
Therefore, the downhole dynamometer card can be defined as a plot of the Page 10 OptiRamp® Rod Pump Diagnostics White Paper Copyright © 2014, Chevron and S&C proprietary information. All rights reserved. 10 calculated loads at various rod displacement positions of the pump stroke; the downhole card represents the load …
What is pump Fillage?
In order to prevent pump off, it is important to know the quantity of fluid entering the pump on each stroke, i.e. pump fillage. As the pump fillage decreases below a certain value, the pump speed can be adjusted or the pumping system stopped in order to allow the reservoir fluids to fill the well bore again.
What is a pump Start card?
PumpStart is a pump activation card that allows customers to pump before they pay, eliminating the need for cash-paying customers to prepay before fueling their cars. • The PumpStart card is not a credit card. It is not a payment card at all.
What is SRP pump?
Sucker rod pumping, also referred to as “beam pumping,” provides mechanical energy to lift oil from bottom-hole to surface. It is efficient, simple, and easy for field people to operate, and can be used to pump a well at very low bottom-hole pressure to maximize oil production rates.
What is pump K factor?
In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
How do you space out a rod pump?
Pump spacing with steel sucker rods normally requires only one to two feet of clearance between the plunger and the standing valve or the bottom of the pump. But because of the elasticity of the Fiberflex® fiberglass sucker rods, it is necessary to allow sufficient spacing to accommodate the rod stretch.
What is a fluid pound?
1. n. [Production Testing] A phenomenon that occurs when the downhole pump rate exceeds the production rate of the formation. It can also be due to the accumulation of low-pressure gas between the valves.
How can I get free gas?

How do I get a QT pump Start card?
To get your own QT PumpStart® card, simply show your driver’s license at the counter of any QuikTrip store and immediately receive your card. For questions regarding your QT PumpStart® card, please call 800-247-3452.
What is SRP in oil and gas?
Abstract. The robust construction, ease of operation and maintenance of Sucker Rod Pump (SRP) is a stand-alone artificial lift method owning mostly to its simplicity. SRP are widely used positive displacement pump in land and offshore oilfield applications for lifting of heavy, medium or light oil with gas and water.
What does a pony Rod do?
A rod shorter than usual, usually placed below the polished rod and used to make a rod string of a desired length.
How do I choose sprinkler K factor?
K-Factor formula for fire sprinklers
- Q = AV.
- Q = A√(2gh)
- q = kp0.5
- k = q / p0.5
- p = ( q / k )2
- for metric calculations: p = pressure in bar. q = flow in litre per minute. k = discharge constant Lpm/bar0.5
- and for imperial calculation: p = pressure in psi. q = flow in gpm. k = discharge constant gpm/psi0.5
What is K in flow rate?
The K-factor is the frequency divided by the flow rate => [1/s] / [g/s] = 1/g. Knowing the K-factor for each calibration point, the factory determines the best fitting K-factor for that particular flowmeter. Calibration points are determined by averaging all K-factors.
What does a polished rod do?
The polished rod is the top and strongest part of the sucker-rod string and it connects the rods to the pumping unit. Its main functions are: to transfer the pumping loads to the surface pumping unit, and. to provide a seal in the installation’s stuffing box to prevent well fluids from entering the atmosphere.
Does 16 oz of liquid weigh a pound?
Answer: 16 ounces (oz) of water is equal to 1 pound in weight.
Is 1 lb the same as 16 oz?
There are 16 ounces in 1 pound. Learn to convert pounds to ounces.
What is a downhole pump card in a wave equation?
The Wave Equation models the elastic behavior of the rod string in its dynamic motion—which allows the surface measurements acquired from the polished rod to be “waved” downhole to the pump to generate a plot of the Load vs Position on the pump’s plunger. This plot is known as the downhole Pump Card.
Why do I need to have a downhole pump?
After all, the only reason for having any of the surface or downhole equipment is to effectively actuate the downhole pump so new fluid will be drawn into the tubing and lifted to surface.
How to tell if a downhole rod pump is worn out?
Dynamometer Cards: the downhole rod pump is completely worn out and is close to picking up the full fluid load in the middle of the stroke but it never does. The well was not producing anything in this condition: need to change the pump.
What happens if you tag a downhole pump?
Tagging is not only destructive to the pump, rods and tubing, but tagging also reduces the downhole Plunger Travel. A 2″ tag is 2-inches of lost downhole stroke. Look at the example Gas Interference Dyno Report at the top of the page: due to the small pumping unit, this well as loosing 7% of its total downhole stroke-length as a result of the tag.
