For all those who are inclined to skip things - please read this carefully. Again the drilling is down to seal integrity first and foremost.

The following is from the geologist covering Glantal -

"Field Analogues.

There are many examples of fractured reservoirs in the world with some of the worlds largest oil and gas fields contained in such resovoirs. Many of these fields are carbonate resovoirs but there remain significant shale, sandstone and coal fractured resovoirs that provide world wide analogies to the postulated fractured reservoir in the coal bearing sequence in the Westphalian at the Glantal prospect in Germany. Such analogous fields include - Anschutz Ranch East - USA, Barque Rotliegand -UK, Cedar Hill - USA, Clair UK, Palm Valley - Australia, Pecos Slope - USA, Powder River Basin CBM" (where Pannonians parent Galaxy operate) " USA, Scotia - Austrailia.

The Powder River, Cedar Hill and Scotia fields are within fractured coal seams, whilst the others are within fractured sandstone reservoirs.

The Glantal prospect has the resovoir target of fractured Carboniferous coal measures of interbedded sands, shales, siltones and coals. The 'Palm Valley' and 'Mereenie' gas fields of the Amadeus basin of Australia are analogous fractured resevoirs. The author "(of this report) "has been involved in their development and a brief review of these fields outlined below provides a useful insight into the nature of such resovoirs that are expected at Glantal Germany.

Palm Valley and Mereenie Field Analogues.

The Amnadeus basin is a large 170,000km2 under explored Proterozoic basin in Central Australia. It has compressional features (fold and thrust belt) and type 2 and 3 fractured reservoirs. It has two producing fields, Mereenie which is Australias largest onshore oil field (200+ mbo) and Palm Valley Gas field with ultimate recovery of 747 BCF gas.

The Palm Valley gas field is about 150km east of Mereenie and sends gas from 11 wells to Alice Springs and Darwin. Palm Valley is a type 2 fractured reservoir with an interconnected fracture network that accesses low permeability matrix of approx 0.1md. Wells that do not effectively inter-connect with this fracture network are uneconomic. Hence the mapping and interpretation of the nature and interconnectivity of the fracture swarm is an important aspect of developing the field.
Palm Valley has been on production since 1983 and provides gas for electricity generation in Alice Springs and Darwin. The field is well into its production tail after over 20 years of production. Production peaked in 1991 with wells averaging 6.4mmcf/d.

The Palm Valley Gas Field is a good analogy to the Glantal prospect as both are a compressive thrust faulted anticlines with clastic reservoir sequences. The nature of the structural deformation and thus resultant faulting is expected to be similar. Matrix porosity and permeability are expected to be low at Glantal as is seen in Palm Valley although porosity is expected to be a little higher at Glantal. The reservoir at Glantal is expected at similar depth to Palm Valley and is likely to be normally pressured."
