Beach has completed the fracture stimulation of Holdfast-1 with the various selected target zones fracturing in line with expectations. The program was designed to be experimental, with the objectives set out below. However, the volume of fluid and proppant injected and the extent and apparent orientation of the fracturing is considered most encouraging.
The key results to date are as follows:
Beach Managing Director, Reg Nelson said, "The completion of the fracture stimulation of Holdfast-1 is a great achievement and overcomes one of the key risk factors associated with the shales, their ability to fracture. Now that we know this is the case, the next step is understanding the performance of the various zones, which will help us focus on the techniques that work best for the various target zones. This information will then be used in the optimisation of the design for the pilot production wells."
Although results to date indicate vertical fractures in the target zones, and hence horizontal wells will be optimal for production, the Holdfast-1 vertical well will nevertheless be flow tested to ascertain what deliverability might be expected from a vertical completion. The clean up flow of Holdfast-1 will take place in early July and is expected be followed soon after by initial flow results. It is anticipated that the flow test of Holdfast-1 will continue for approximately three months. Information gathered from the shale wells will likely result in a resource booking in early August.
It is anticipated that the fracture stimulation of Encounter-1 will take place in the December quarter, pending the availability of the crew and necessary equipment.
