dear gents i have a question about ESP POWER CABLE my question is ,why during RIH ( RUN IN hole ) cable PHASE TO PHASE measurements using fluke increase ,,while PHASE TO GROUND measurements using DC megger test decrease. as an example PH-PH IS 3.1 ohm AT ZERO TUBING,,after 100 joints is 3.7...

Thx gents for all your help it really helped me alot,,but i have another question so thanks for your patient overload and under load setting and its time delay. some engineers use to set over load on 115% of running amp, some set it one 115% of rated motor amp,,with start delay zero seconds...

Sure it affect on production,, I have low flow with decrease in discharge pressure,low whp,and increase in chp and increase in intake pressure.,so if I have big hole it will take more amp!?

Dear jents I have a question about tubing leaking in Esp systems,, I want know what is the affect of tubing leaking on motor amp (running amp)as I read on some papers that it Dec the amp,and which I think not correct, any help please. Second thing,

Dear Sir U mean that 5700bpd are 4995 due to fvf value? does this value change during operation and does it effect that mush in production,, if I wanna calculate it during operation what factors affecting it. Second question, is there is any operation or ajob that can be done to decrease the...

Sir it is not opening, can u resend me the link again please

thanks guys for ur respons the FVF OF 1.15 is a total values not oil only ,and the curve i have is from application engineer based on down hole data given by owners i wan to know is does fvf have a range like from (0.1 to 3) as an example,,,and if i calculated a new fvf difference from what...

dear jents case is as follows; i finished the well's installation and started it up no problems. i waited until the well stabilized, Pi and Pd are stable and all is good. The client starts taking production readings. Surface rate is 5000 BPD, i look at the curve and find that the operating...

dear gents i have a question about ESP considering esp submersible motors which is more practical and correct way in calculating motor surface voltage,do i use the motor name plate data rated voltage and ampere or i use motor rated voltage and use motor running amp in calculating voltage drop...

What kind of data u need and I will get it all sir

Sir I closed chock and WHP raised from 150 psi to 500 psi in 13 minits, then they did a backwash.job with diesel and and.operator the pump, nothing changed, low rate with low discharge pressure and increase intake pressure, the sample is heavy oil and gases

Dear gents What could possibly cause a well producing 1400 BPD, to produce 700 BPD intake pressure inc and discharge pressure Dec,amp is constant. Production engineering open chock more and increase frequency, nothing happened what cause that!? Please advise

I don't get it how it is helpful, what is the relation between casing and tubing pressure

I didn't have pressure gauge on casing, how it could be helpful in this case if I have one?!

Dear gents I was in a troubleshooting job on a well,they said the amp is.constant with no flow, and I found that from there reports that there was flow with the same amp but now no. I operated the pump and the amp was constant not Dec for an hour but no flow found, I opened chock completely...

Dear Eng/David I respect your comments on me and sorry for my words,but i really searched alot and found nothing and that pdf or paper or any thing can be my reference just all. appreciate your help.

hi i have a ques about ESP troubleshooting if i have low flow how could i know that there is a hole in tubing,,and if i know does its location matter i mean if it is in the joints above pump or in the middle or last joints before well head.and i waana pdf about esp troubleshooting that may...

i have a ques i have a generator and 2 transformers of Delta/star 210 kva and a 3 phase induction motor my ques is i want a wiring diagram of how we can connect 2 transformers in parallel and in series from the generator till the motor plz if any one have wiring diagram send me plz thx

Thanks for ur help , i found that if both have the same ka its ok to be connected but in a limited applications in lv zones.

i wanna an article or something from any electrical codes that say it is ok to have a mcb replace a mccb
