In every case the same questions are asked: where are the zones of economic interest,
how thick are they, what is the distribution of material in each zone, what is its
quality, and are the rock properties conducive to economic extraction?
The answers come in large measure from wireline logs (also known as well logs,
borehole logs and electric logs). The first such log was run in an oil well in 1928, and
it was the oil industry that drove developments for the following forty years. Most
texts dealing with log analysis continue to be written from an oil company
perspective.
Slimline logging, the subject of this book, is associated with the lower cost
environment of the coal and non-hydrocarbon minerals industries. The slirnline name
was coined by the BPB company which, more than any other has promoted the use of
logs within these industries. Crucially it was the realisation in the 1960s that coal can
be delineated accurately by high-resolution density, neutron and gamma ray logs that
opened up this new market, and BPB Instruments was established in 1970 to exploit
these ideas commercially.
Today the company operates as Reeves Wireline Services, and has itself expanded into
oilfield logging, giving it a unique perspective that comes from the cross-flow of ideas
between scientists working in diverse disciplines.
This book is nevertheless writren for the minerals log analyst. Its content reflects the
importance of coal in the development of logging for mining applications, but the
principles are equally applicable to other mining activities.
