XFER Multiphase Transfer Pump: Lower Pressures, Fewer Facilities

The IJACK XFER is a multiphase transfer pump. It moves oil, water, gas and solids from the wellhead to the battery in a single pipeline, with no separators, pumps, compressors or storage tanks in between. It handles anything from 100% liquid to 100% gas, and solids are not an issue.

What it does at the well

The XFER lowers casing, well and flowline pressures, individually or simultaneously. Lower pressures let more oil and gas reach the surface, so it is one of the simplest ways to get more production from existing wells instead of drilling new ones. Lower pressures also:

• extend downhole equipment life
• reduce PCP torque rates
• let plunger lift systems cycle more often
• reduce the injection pressure gas lift systems need
• let more wells discharge into existing flowlines
• remove the need for a separate casing gas compressor

Installs are quick, the footprint is small, and each unit can be monitored and controlled remotely through RCOM.

Where it replaces facilities

Because the XFER pumps the full emulsion straight from the well to the battery, it can take the place of group lines, separators, compressor stations and pump stations. Customers use it to:

• replace older, underutilized facilities where production no longer justifies the operating and maintenance costs
• avoid building new facilities
• stop trucking fluids from the well pad to the battery
• end gas venting and flaring
• replace screw pumps, since the XFER handles the full emulsion with no fluid recirculation

We have replaced 500 HP screw pump packages with 125 HP XFERs and achieved lower intake pressures, adding production. Less installed horsepower means lower power costs and a smaller carbon footprint. Lower casing, well and flowline pressures also mean fewer methane leaks.

The XFER can also work as a booster pump in waterflood and disposal systems that lose pressure at their most remote points.

Pressure capability

Pressure differentials for a single ANSI 300 unit are up to 480 PSI, and up to 740 PSI with units in series. See XFERs in series for how the delta P of each unit stacks, and how ANSI 600 and 900 units reach higher discharge pressures.

XFERs come in several sizes:

• XFER 1670: a 16" barrel, designed for a customer who needed more than 400 PSI delta P. Maximum delta P is 480 PSI.
• XFER 2270: the 22" series. Maximum delta P is 250 PSI.

Applications

XFERs work in both single-phase and multiphase service. A high-temperature version was built for a SAGD steam application in northern Alberta. Four XFER 2270 units were installed in the south Viking play.

Gas and liquid flow by model

XFER 1670 (355 cc): gas flow against liquid flow at its maximum 480 PSI delta P, at 100% efficiency.

XFER 2270 (280 cc): gas flow against liquid flow at its maximum 250 PSI delta P, at 100% efficiency.

In the field

Two 125 HP XFER 2270 units that reduced intake pressures by 20 PSI with 75% less installed power.
