Abstract
The first use of a logging-while-drilling (LWD) bed-boundary mapping (BBM) tool in Australia has demonstrated the ability of the device to locate formation boundaries along significant lengths of the wellbores, reducing the uncertainty that would have been present if only a conventional suite of tools had been used. In the first well of the program, the thickness of the target reservoir was significantly less than expected, resulting in the borehole exiting the base of the sand shortly after exiting the casing shoe. Data from the BBM tool guided the design of a sidetrack well off the initial failed design resulting in a successful well with an initial production of over 16,000 barrels of oil per day (BOPD).
