Baker Hughes announced yesterday the commercial release of its NextWave production rejuvenation solution, which helps operators boost production, improve sustainable cash flow, and increase booked reserves in existing unconventional wells that have more production to offer.

“When unconventional wells are not performing to expectations, operators often try to meet production targets by continuing to produce at low rates, drilling more wells, or refracturing the existing wells using a ‘pump and pray’ approach,” said Hans-Christian Freitag, Baker Hughes vice president, integrated technology. “In today’s oil price scenario, however, operators need a more economic and consistent method of improving recovery. The NextWave production rejuvenation solution gives them that ability.”

The NextWave solution is based on a logical, four-step stage-gate process that includes candidate well screening and selection, well diagnostics, programme design, and wellsite execution.

First, the Baker Hughes team analyses field production data, well histories, and decline curves, and ranks wells according to rejuvenation risks and economic potential.

Second, the team performs comprehensive well diagnostics, including review of original completions and stimulation design, assessment of the wellbore’s structural condition and mechanical integrity, and evaluation of reservoir quality and producing intervals.

The third step is designing the appropriate rejuvenation programme, which can include wellbore cleanout, installation of artificial lift, recompletion and/or stimulation via a targeted refracturing programme.

During the fourth step, the Baker Hughes team designs a detailed operational plan, manages the wellsite activities, and monitors and collects data on treatment effectiveness to help further drive efficiency, reliability, and reservoir understanding.

This approach provides a pathway to improving the economic sustainability of North American shale plays, according to Baker Hughes.
