IN THE CUSTOMER’S WORDS:
“Aggreko was able to manage all of our power requirements, from sourcing the right filter management company to customizing a power solution that helped us improve production over and above our original estimation. We will continue to look to Aggreko for all aspects of our auxiliary power management.”
Aggreko Solution
Operations Manager, BC Operating
The Situation
An oil and gas producer in West Texas, BC Operating, had limited access to grid power. As a result of limited electricity from the grid, more than 16 of its wells were underdeveloping or shut in.
BC Operating needed a temporary power solution; however neither diesel, LPG, LNG nor CNG as a power generation fuel source were economic options. Field gas was available, however it was in the form of hazardous wet-sour gas, containing greater than 200 ppm of H2S. A permanent solution to clean the gas also proved uneconomical. With utility upgrade six months away, the operator needed an alternative solution quickly.
The Aggreko Solution
The operator consulted with Aggreko to determine a better power management strategy. Aggreko’s technical specialists helped engineer a cost-efficient solution to clean up the toxic wet-sour gas and turn it into a fuel source to help power the natural gas generation station. The temporary station was designed to work in parallel with the utility grid, providing incremental power to supply run operations.
The solution generated greater than 10:1 payback. The temporary power system was able to:
- Reduce the H2S levels to 0 PPM via SulfaBate Tower
- Reduce the liquids content of the gas via multiple gas liquid separators
- Utilize a temporary flare to purge/test gas prior to being placed into application
- Parallel and base load with the utility grid @ 12.4 kV utilizing 2 x 1 MW natural gas generators
- Power a fully operational site in less than one week
With the additional electricity supply, the system allowed eight well conversions from rod pump to electrical submersible pump (ESP). This change increased operational capacity to immediately begin drilling new wells and continue toward 100% operation of available production.
Why was Aggreko chosen?
Because Aggreko could adequately supply the power needed to operate submersible pumps, the customer was able to increase production , and to make efficient use of otherwise unusable gas.
Aggreko offered a safe, scalable application to economically deliver reliable temporary power to the field.
