Drilling Coal

19 December 2017 Lectori Salutem,
I was wondering if any of the esteemed members of the forum could share 'best practices' (or perhaps the not so best practices) to drill coal beds.
I am aware that Statoil has a method called Low Energy Drilling, but have no details on this.

Many thanks in advance.
Harald Benning
