摘要

Acceptable data quality for formation evaluation forms the foundation for understanding the petrophysical and reservoir properties, coal quality and properties and pay zone identification. The petrophysical logs are used in both subsurface modelling and to optimise the well completion strategy, ensuring effective coal dewatering and desorption for gas production. At the moment, the industry common practice for data acquisition is to use open-hole wireline logging tools, which were developed primarily for the oil and gas industry. These tools are designed for higher pressure and temperature specifications compared to the reservoir conditions normally seen in coalbed methane (CBM), commonly called coal seam gas (CSG) in Australia. This results in heavier tools, larger logging trucks and increased manpower requirements than seen in mining logging operations.
