A Look at the Well Pump Installation
During the summer of 2016, Nickerson Company received a request from a western mining operation for a quote to provide field installation services. We were asked to install a 1,500 HP submersible well pump with a total setting depth of 3,088ft—our deepest well pump to date. Nickerson Company was awarded the job to install the pump and got to work.
This installation was successfully completed on time and 25% below the originally estimated cost. The mines’ superintendent of operations thanked the Nickerson Company Crew for “doing an outstanding job, done well and done safely”. The superintendent went on to say, “Nickerson Company has demonstrated again that we can count on you. [We] thank you for helping us save a significant amount on installation costs”. The Nickerson Company Field Service team is currently scheduled to install a near duplicate of this pump in June of 2017.

About Schlumberger
Schlumberger is a large oilfield equipment and services company. The Schlumberger equipment was used for this job because the parameters and specifications of this pump application were highly complicated and specified. Schlumberger proved to be instrumental in achieving success for this unique challenge.
Interesting Facts About the Deep Well Installation
The pump column pipe used for this application is an API-specification oil field material suitable for the weight and setting depth. The API torque make-up guideline for the 7-inch pipe couplings is 3,130ft/lbs. The correct coupling torque is critical and is verified during the field make up of each joint with a calibrated torque gauge attached to the hydraulically powered casing tongs.
The overall assembled length of the pump assembly including the motors and protectors amounted to 92.91ft.
The total dry weight of all of the pump components assembled into the well was nearly 90,000lbs.
The specialized tools and equipment utilized by a four-person Nickerson Company Field Service Crew to install this equipment included the following:
- 135-ton mobile hydraulic crane
- 40-ton mobile hydraulic crane
- 23-ton mobile hydraulic crane / hydraulic power pack for casing tongs
- RT fork lift
- 100-ton API bowl and slips
- 7-inch, 150-ton side door elevators
- 13-3/8-inch, Eckel Hydraulic Casing Tongs
- Bull tong back-up
The Nickerson Company looks forward to unique and challenging projects. We never back down from difficulty, and pride ourselves on completing work ahead of time and on or under budget.

I liked that you said that one reason to consider hiring a professional to install a water well pump for your property is that they have the proper tools and equipment to complete the process correctly. I have been thinking about installing the water pump myself but I have been worried that I wouldn’t be able to do it correctly. I will be sure to hire a professional to ensure quality.
Installing a deep well pump may be more complicated than installing a shallow well pump. It requires many types of equipment so I will have a professional set up a deep well pump when I decide to install it.
Yes If a pump is being raised with a 30”long spool 12” casing flg x flg. . Has a discharge head existing and pump will just go up 30” from where it is in the well! So if I raise the pipe to first collar below the pump head and sit it on the well casing that is flanged , can I pick the next 20 ft length of column up sit a well clamp on the well casing, screw the 4” x 20 ft column length off while holding it with another clamp at the top and slip the 30” long x 12 “ flg x flg spool under the dangling column tie it temporarily to column, then drop the column onto couplin on the existing column sitting on wellhead. Remove wellhead clamp and drop the 20 ft into well while bolting up the 12” spool. Screw head on and be done? So pump head will be raided 30” with the 12” x 30 long Flg x flg. Column spool?
