Beacon Energy plc continues clean-up on Schwarzbach-2(2) while beginning sand jetting operations to stimulate the well in the Erfelden field, Germany.
PERFORATIONS
The rod pump was installed in late 2023 but production remains at approximately 40 barrels of oil per day, indicating that the reservoir near the wellbore is invaded by drilling fluids restricting flow rates.
Sand jetting, with a coiled tubing unit, will focus on the oil-bearing reservoirs in the Pechelbronner-Schichten sandstones.
The technology uses a high-pressurised sand slurry to create deep perforations beyond the zone invaded with drilling fluids.
Beacon expects that the deeper perforations will increase communication between the oil-bearing reservoir and the wellbore to increase production rates.
Operations will take 10 to 14 days including re-installation of the rod pump and resumption of production.
The well is expected to take several weeks to clean fully, after which in April 2024, an electrical submersible pump will replace the rod pump to maximise production.
As part of the sand jetting operation, Beacon will recover a downhole pressure memory gauge to understand both the formation pressure in the oil-bearing reservoir and the restriction of flow around the wellbore caused by fluid invasion.
The company said it was fully funded for the sand jetting operation, estimated to cost less than €500,000.
Chief executive Larry Bottomley added that Beacon remained fully focused on establishing optimal production from SCHB-2(2.) as quickly as possible.
“Despite these operating challenges, the exceptional technical results of the SCHB-2(2.) well have materially increased the potential reserves of the Erfelden field and provided confidence on the productivity potential from this and future wells.”
