Amersfoort Project
Flagship Amersfoort Gas Project-Exploration Rights ER38 and ER56
Exploration programs conducted have proven the existence of large accumulations of on-shore, shallow gas with strong flow rates, that host the potential to develop a significant gas production field. The gas is found in both the sandstone and coal formations across both ER 38 and ER 56, with gas identified in every exploration hole drilled to date.
The average depth of all holes drilled, ranged from 150M to 550M. This is relatively shallow in comparison to other on shore CBM gas fields globally. Coal seams identified are between 1M and 4M with cumulative coal measures of up to 25M.
Initially, 20 exploration core holes were drilled. This culminated in significant gas shows in both downhole logging and laboratory canister desorption. Of the 7 permeability pilot test wells drilled using a simple barefoot completion method, all wells spontaneously flowed gas to the wellhead.
Through further exploration and the continued successful use of an aeromagnetic survey, the focus will be to expand the gas field and to quantify the resource. As further exploration is carried out on ER 38, this will test deeper formations and probable higher gas pressures than encountered in ER56 on drilling of more permeability test wells.
