Enhanced productivity of coal seam gas wells by continuous gas circulation (administered by The University of Newcastle) (2019–2023)
Abstract:
The intended outcome of the project is to develop foam assisted continuous gas circulation for dewatering new
and existing coal seam gas wells.
The potential benefits of this new method include enhanced gas production, better well control, reduced costs and
better environmental effectiveness. The proposed solution eliminates the need for mechanical pumps which are
currently used for
dewatering, and which fail regularly due to gas and solids accumulation within the production wells. With no
subsurface moving parts and the capability to easily handle solids, continuous gas circulation could achieve
significant savings in
downtime and maintenance costs, potentially saving hundreds of millions of dollars annually in the coal seam gas
industry.
