I am newbie in the Oil and Gas Industry, a facilities engineer to be specific.
I have been tasked with recommending an ESP for use in one of our reservoirs, but I am confused as to how to go about selecting one. I am in touch with a vendor and they have requested a bunch of information - reservoir data, drilling plan - which I have forwarded to them. However, I am confused as to the critical parameters to look out for in selecting a pump to meet our needs. Any assistance would be highly appreciated.

Thanks in advance.

Doki:

Any engineering or production company proposing to buy a major piece of equipment – such as a submersible electric-motor driven pump – has to have a set of minimum requirements that it imposes on suppliers of the desired equipment. These are the normal, expected engineering specifications that are issued by the purchaser (your company) to the expected supplier(s). These are issued with the RFQ (Request for Quotation) and then applied to the final purchase order (PO) with any deviations agreed to during the final negotiations prior to purchase. These specifications are often based on – or referenced to – industry standards, such as API standards on the items in question. Your company has the responsibility to identify what is the minimum and maximum details and specifications that it will accept in the eventual purchase. Your purchasing agent or department should indicate this to you as well as your engineering department or head.

If your company is doing business in the oil and gas business, it should already have these standard specifications within its files and or resources. It is the purchaser’s responsibility to fully identify and specify what it is that he/she wants to purchase, when, and how. Therefore, you should be guided and instructed as to your company’s needs and desires in this respect. If you or your company do not have these documents already prepared, then I recommend that you prepare them or have them prepared. This will avoid a lot of future problems, fights, complaints, and possible lawsuits between you and your supplier regarding what should have been delivered, how it should work, how it should react, how it looks, how much energy it consumes, how long it lasts, etc., etc.,

Thanks for your prompt response, but I don't think that you got the crux of my question. My company already has all these in place, but my question was geared towards the technicalities involved in selecting an ESP for a particular reservoir...i.e. what well data should I use to arrive at my desired pump.

And I don't think you got the crux of my response.

The specific answer to your specific request is in the RFQ or in the PO purchase specifications package - which has to contain what is called a "Specification Sheet" or a "Data Sheet" and which clearly and succinctly outlines all the required and necessary technical engineering data required to identify the service and the operation of the equipment (pump, in this case) in question.

I have uploaded a set of industry-quality Data Sheets to our Forums in the past and if you search for them you can find and upload them. If you can't, just tell me and I'll upload them again in this thread. Let me know.
