I'm not an expert at gas pressure regulation. Though, I have a MIG welder with a Radnor brand flowmeter regulator. I think the thing that you are missing here is that there is a single stage regulator built in to your piece of equipment. My flowmeter regulator is designed for up to 3000 PSI...
It is common to run a spectral gamma ray that separates out the Potassium, Thorium, and Uranium components of the radioactivity when you run a well log in the Permian Basin. The Permian is considered to have "Hot" radioactive water. When you run your well log analysis to look for clays, you...
What are you trying to optimize? Wells, artificial lift, flow lines, facilities?
My #1 recommendation is to spend as much time in the field as possible. Ask the field personnel what their top 3 problems are and see if there is anything you can do to address those issues.
#2 - get a copy of the...
I recommend the following:
Gather wellhead amps and volts or VFD output volts and amps. Multiply them together and divide by 746. HP = (Volts * Amps) / 746
Now plot your horse power as a function of time.
By looking at any common radial flow or mixed flow pump curve, we can see that if fluid...
The company I have worked for supposedly has a policy that there is one rig supervisor for each pulling unit. In reality - there are often 2-3 rigs per supervisor.
I have heard about companies having approximately 100 wells / production engineer when the wells are new. Though, some companies...
The objective is going to dictate what conveyance method is required. These services are usually charged by the hour or by a day rate. There will also be minimum job charges and mobilization charges.
I would expect the costs to be (highest to lowest) drill pipe, coiled tubing, and then tubing...
It is possible that there is are different heights of liquids in the two strings above the point of communication leading to different surface pressure readings. This is based on the assumption that oil, gas, and water are present in both strings. It would be helpful to draw a wellbore diagram...
All, thank you for your recommendations.
Dhurjati Sen:I will carry out a visual inspection, look for damage, and will be using city treated drinking water for the testing. I will hold the max pressure for 10 minutes.
r6155: Thanks for the information.
EdStainless: I will see about using a...
I recently purchased a 240 gallon pressure vessel that I plan to utilize as a compressed air storage receiver in my shop. The vessel was manufactured in 2002 and is rated for 200 PSI MAWP @ 400 degrees F. The vessel is designed to be installed vertically. I plan to operate this vessel at 175...
To answer your question: I don't know. It seems more likely that the simplest explanation is the right one, though. Do you have a produced gas analysis from when the well was naturally flowing? Can you get a gas analysis of the suction and discharge sides of the compressor and at the casing...
Are you measuring the annulus pressure at sea level or at the mudline?

I know this is an old thread... How deep of a borehole are you talking about? 20 feet or 20,000 feet? In oil and gas drilling regional charts are developed using average pore pressure gradient vs fracture pressure gradients to determine what depth to set the next casing string. The website...
Are you trying to verify that you just don't have a hole in your tubing or trying to verify tubing integrity for an upcoming pressure pumping job? Do you have open perfs above the packer? Can you just hook up a rig pump / kill truck to the backside and test the casing, packer, and tubing at the...
I work in the production department for a decently sized publicly traded independent oil and gas company. Production is a lot more stable environment than some of the other disciplines and I no longer get phone calls at 4:00 AM on Sunday morning. I have worked with many production engineers who...
M3Engi, by oil level do you mean fluid level over pump?
If so, you can roughly calculate the fluid level over pump by doubling the pump intake pressure.
Though, if you wanted to get to a more accurate value, you can take the pump intake pressure value and subtract the casing pressure. Then...
Jose, ensure each tubular and component is rated for at least as much pressure as is likely be encountered plus a safety factor. Do you have a Halliburton Redbook or other source to look up the API accepted values for burst pressure for each different size/weight/grade of casing and tubing?
Jose, for the common plug and perf completion method, you are correct. The plug and guns are run in the hole together. There are switches between the plug and each cluster of guns. The switches allow the operator to detonate each charge separately by applying either a positive or negative...
High_Volt, I have heard about detecting holes in tubing the way you are describing by using two fluid level guns. One is tied to the casing, one is tied to the tubing, and then you shoot down the tubing but listen using both guns. Google "echometer hole in tubing" and click on the first link...
When the underload trip occurs, touch the tubing with your hand. Does it start getting cold and can you hear gas expanding and liquid slugging? Your well may be flowing up the tubing naturally after the pump turns off. The pumps are causing a pressure drop since they are no longer spinning which...
I'm assuming the tubing x production casing annulus had the high casing pressure. Is this correct?
As you suggest, you could have a casing leak. Was the casing pressure the same as the tubing pressure?
Production facilities have some oil carryover that makes it to the injection / disposal...
