    Pump type suggestion

    Hi all, I have an application for boiler refeed that we are designing and require a small booster pump. We have high TDS (not exactly sure what the number is as yet though as it is going through a settling tank), and a high solids content. The fluid is water, the temperature is 85C (185F) and...

    Kind of a dumb question about drilling unconventionals

    Priceless response David, it certainly matches my observations also. If you have some firm numbers on how much the drilling department saves on this type of decision, I would appreciate it. My calculations show about 200 000 dollars over the drilling and completions, but that money is easily...

    Kind of a dumb question about drilling unconventionals

    I have noticed that many oilcos tend to drill unconventional wells and run 4 1/2" casing. While this keeps the cost of the drilling program down, I do hear of multiple problems when trying to produce these wells. For example, landing a rod pump to about 70 degrees as opposed to running it to...

    ETU

    ETU = Endless Tubing Unit? (aka coiled tubing unit)

    The Whole Process

    Good advice. I would also suggest that you purchase one more book (yes, I know you have the textbooks your profs suggested) but I would add the Petroleum Engineering Handbook by Bradley. It's big, expensive, but I believe it is a great resource to really dig into some of the more arcane...

    pump jack diagram

    Lufkin and/or Ampscot have great diagrams in their manuals. Call Lufkin at 936-634-2211 and ask for installation manual CU-02. Alternatively, contact Weatherford-Ampscot at 1-800-AMPSCOT and ask for their Operators Manual. They would probably be pleased to provide you with a copy of their...

    Has anyone seen this before?

    Hi. There is not a lot of info, but I'll give 'er a rattle: It looks like at 3 pm Wednesday, the well began loading with fluid, as your gas volume is decreasing. This may have been a gas locking situation of the insert. At about 6pm, the well unloaded and flumped and flailed for a while...

    gas well deliquification using PCPs

    Koma72, please advise a couple of parameters on the well. Is it producing water with any oil? Generally oil in conjunction with water will make the pumps last longer as the oil tends to lubricate the elastomer. How much gas does it make? We have found that, if it is 100% water, the amount of...

    Friction Loss Books

    I don't know how exact you need the information to be, but the book, "Flow of Fluids through valves, fittings and pipe" by Crane Limited is a great resource. (technical paper # M-409) I think its cost is around $50 now, but it is worth every penny for me (petroleum).

    HOW CAN I SELECT A ELECTRIC MOTOR FOR A PCP PUMP?

    Hi Neca You didn't say if this was for downhole or not. Assuming it is; 1) Weatherford and others have software to determine the proper e-motor requirements for your application. 2) There is a couple of quick and dirty calculations you can do: Torque = [total net lift * displacement...

    procedure on foam depression tests?

    I am seeking information on the PROPER technique for shooting a foam depression test. I have looked at Echometer and others on the web, but there does not seem to be a consensus that I can pass on to our operations people on both HOW-TO, and Interpretation. How do others handle this situation?

    Seeking information on borescope/endoscope

    Good day all. I am looking for a good quality (really inexpensive) borescope with which to examine oil/water piping with. Ideally it would be fibre optic, with length to about 15-20 feet. Is there a mfg. that might make something like this? The only thing would be that the focal length of...

    How to calc. visc. of oil-water mix?

    Thanks Andrey! Where did you find this at? Is there a single "production" reference (i.e., text book?)

    How to calc. visc. of oil-water mix?

    I am looking for a way to determine the viscosity of an oil water mixture. Typically, all the information I have available is the API of the oil, and the density of the brine and %'s of each. Can anyone offer any insight? Thanks in advance.
