Hollow Sucker Rods

Currently at least one major manufacturer has 7/8” hollow rods available.

The pin is the same as a 7/8” but the body is different.

The body of the 7/8” rod is 1.049” while the ID is .434”. The wall thickness is 0.308”and a load carrying area of 0.716 sq. in. is present in the body. The wt/ft is 2.53#/ft.

Currently the product is from AISI 8630 material with a tensile strength of 115,000 psi, minimum.

Coiled Tubing as Sucker Rods in Slim Hole

Wells?

SPE paper 56671, is entitled “Coiled Tubing Used as a Continuous-Sucker-Rod System in Slim Holes” .

This paper discusses a method of producing 3 ½ casing wells using coiled tubing as a sucker rod replacement.

Slim-hole Gaslift


Gaslift Advantages l

Lift gas present?

Handle high rates

Flexible to intermittent

Unobtrusive

Easy to diagnose

Gassy wells good

Crooked holes OK

Corrosion not too bad

Disadvantages

Handle solids

Not efficient

Viscosity is problem

Freezing hydrates can be problem

High producing formation pressure

Pressure on Casing


Gaslift Options

How the Jet Pump Works

Wellbore Unloading Using a Jet Pump



Jets: Summary

Can run jet inside 1-¼” CT inside 2 3/8” or 2 7/8” tubing with gas production up the

casing. Jet pump is retrievable with pumping action requiring no tubing pulls to replace worn

pump.


Jets: Summary, Con’t

Case (1):

One (1”) coiled tubing is used as a power string. 1-1/4” coiled tubing is used at the return string and 2-7/8” tubing is used for gas flow. For 2500’depth, hp is 26.4 for 100 bpd liquid with 4000 psi needed as power fluid pressure.


Jets: Summary, Cont’d

Case (2):

1-1/4” coiled tubing is used for the power fluid string. 1” coiled tubing is used as the return string and 2 7/8” tubing is for the gas flow. The hp required is 13.9 at 2600 psi power fluid for 100 bpd total fluids production. The depth is 2500’. This is a “free pump” installation.

Slim Hole Plunger Lift


Reference for Slim Hole Plunger Lift

3.5” SLIMHOLE PLUNGER LIFT SYSTEM USED IN THE WAMSUTTER DEVELOPMENT ASSET IN GREATER GREEN RIVER BASIN, WYOMING

BY

GRUCE GERRAD, BP, AND BILL HEARN, WEATHERFORD ALS

SOUTHWESTERN PETROLEUM SHORT COURSE - 2003


Plungers in 3 ½ Casing

Conclusions:

The 3-½” slimhole plunger has been successful, with two of the 40+ installations being removed for being unable to flow back against line pressure. The 3 ½”plunger is far less restricive and lifts more than 1 ¼” CT and 2 1/16” tubing. It is cheaper to install over 2 1/16” tubing.

From preceding reference by Gerrad and Hearn:


Summary:

For sim hole artificial lift, some options exist, but depth and

rate options are reduced considerably.

If gas separation is desired, options are reduced even

further.

Plans must be made for what expected rates may be or

drilling slim holes will severely reduce the possible production

rates.
