Standard Jet Pump

The standard jet pump was the original model that introduced the technology to the oil industry after it had pumped water wells for many years.

The pump manages the three streams of fluid flow internally or within the body of the jet pump which in 2-7/8” tubing is a maximum of 2.31” outside diameter.

Figure 1.0 shows how three fluid directions flow through the pump, 1. Well inflow, 2. Power fluid and 3. Discharge, where the inflow and discharge limit maximum production capacity.

This feature makes this model flexible and adaptable to circulation sleeves gas lift mandrels and fixed concentric tubing completions.

The design facilitates well completions that allow downhole gas separation to pump low pressure gassy reservoirs as is outlined on the GPT catalog.

The model has been improved with larger internal passages.

See the complete GPT catalog for fixed concentric jet pump jet, sliding sleeve jet pump, parallel free jet pump and the improved Tritan standard jet pump parts list.

Jet Pump performance simulation programs do not model jet pump abnormal internal pressure losses because there is no input of the model being simulated.

These programs include a linear rate related pressure drop with no limits.

Reverse flow jet pumps are rearranged standard model jet pumps, but the different flow pattern inherent with reverse flow do not have the same production limitations.

Reverse flow jet pump limits are associated with tubing sizes. Nodal analysis programs are reasonably accurate with tubing pressure losses.

High Volume Jet Pump

Increasing oil well production rates in the 80’s resulted in development of the high- volume jet pump that provides larger well inflow passages in the special high volume bottom hole assembly, (BHA) leaving the jet pump body to manage only discharge flow.

The high-volume pump has been documented to produce more than 20,000 bpd in reservoirs that support the energy exchange in the venturi principle for this rate.

This allows the use of much larger nozzles to provide the maximum production and lift capacity.

Figure 2.0 shows the high-volume jet pump and the twelve ½” passages in the high-volume BHA that allow inflow from the well versus the twelve less than 3/8” holes inside the part (crossover) of the standard pump models that also manage inflow from the well.

Only full product line jet pump manufacturers provide the high-volume jet pump.

Traditional Jet Pump

GPT supports and serves jet pump systems worldwide with original designs and spare parts and in many cases updates design improvements.

Most existing jet pumps operating around the world are of the standard design where production rates and lift capacities are within the quipment’s capacity.

Parts are made to the original manufacturer’s specification as a standard; however, new materials of construction, treatment and coatings can be provided to extend usable life when conditions warrant improvement.

Titan Jet

GPT optimized internal passages in the jet pump, bottomhole assembly (BHA) and standing valve to increase production capacity and efficiency of the traditional jet pump.

The TITAN Jet pump continues to use the traditional nozzle and throat to minimize inventory cost when there are other traditional jet pumps in a location; However, it introduces increased flow areas and memory pressure / temperature gauge carrying feature.

The TITAN jet pump is a mid-way solution to continued standard jet pump models with improved efficiency.

The improvements include larger flow passages in the fishing neck, elimination of the inner tube to increase inflow passages, alignment of pump discharge with the passages in the BHA and more reliable outer seals.

Jet pump to BHA alignment also allowed introduction of a high-volume standing valve.
