designed to perform well repairs and well stimulation

20t Flush By Unit

The Workover Unit „ FBU20 “ is designed to perform well repairs and well stimulations and is used for the following operations:

• General w orkover operations

• Well stimulations

• Assembling/ disassembling of piping and pump supports

• Preparation of production w ells for special treatment (e.g. Frac)

• Pump and circulation operations

The advantages of the Flush By Unit FBU20 • The Flush By Unit is typically used to perform

the same function as a fully outf itted w orkover rig, but limited to shallow w ells.

• The unit is much easier and faster to move and set up, and are typically manned by few er operators then conventional w orkoverrigs.

• Flush By Units are much more adaptable to customer’s unique requirements.

ProblemSeveral problems can arise at w ell sites. Rods can break dow n-hole due to additional torque caused by sand or corrosion, leaks can develop, or pumps need to be replaced. Service rigs can be very expense, so you need a cost-effective, yet versatile solution to provide various dow n-hole w ell services.

AdvantageEffective Workover operations and well stimulationsThe C.A.T. Flush By Unit FBU20 includes a holding tank and triplex pump; contaminants (sand) can be circulated out of the w ell. The unit also used extensively to circulate solvents or other chemicals, to remove paraff in and asphaltene.

The Flush By Unit can f ix rod breaks, replace polish rods, pack leaks, trip rods and pump out of the w ell, also the tubings, f lush sanded-off or w axed-off wells, change pumps or drive units as w ell as various w ell trouble-shooting that can maximize your w ell production.
