We sped across the surface of Lake Semayang with the bottom only inches below us. Using traditional long boats – with light but powerful engines – twenty-seven of us were headed for Semayang village, on the north central ‘coast’ of the lake. We were there as part of a geological field trip examining modern environments […]
The Society for Organic Petrology Annual Meeting: Hydrocarbons in the Tropics – On the Edge Field Trip The 2015 TSOP Post-Conference field trip is scheduled to take place from Thursday, 24th September to Sunday 27th September. SEE LINK: www.tsop.org for more about the society, the 2015 Annual Meeting in Yogyakarta and the field trip to Kalimantan We […]
The Indonesian Archipelago is vast, diverse and exciting. The culture is as deep and varied as it’s geology and history. It is a region at the nexus, or on the edge if you will, of almost everything; and that includes hydrocarbon generation. Indonesia has been exploiting petroleum for almost two hundred years and coal mining […]
Internationally refereed articles on coalbed methane in Indonesia are rare. However, an article addressing heat flow effects on a coalbed methane reservoir in East Kalimantan, Indonesia has recently been published*. You may well ask, so what? Indeed a good question; here is the context. There are many of us who have been sitting at the […]
Unconventionally produced gas (coalbed methane, shale gas, tight gas etc) will become increasingly important in the world’s energy mix. The success of the shale gas plays in North America only reinforces just how economically important these deposits are both on continental as well as global scales. But, despite its success, there are large unknowns surrounding […]
Considering the impact that coal has on the world, there are surprisingly few technical books dedicated to the subject. Romeo Flores, recently retired from the US Geological Survey (but still a Cipher Associate [see: https://www.ciphercoal.com/the-team/dr-romeo-m-flores/ ]), has gone some way to remedy this situation. His book “Coal and Coalbed Gas: Fueling the Future” has just […]
For those of you following this blog, you might remember that last year, on my annual field trip for the Geology 483 class (University of Canterbury), I lost my hammer. As is usual, this year as last, we visited the Denniston Plateau, which has an excellent geological section extending from the basement (Greenland Group meta-sediments; […]
In June of this year, Gas Specialist Chris Nelson was in Botswana overseeing desorption testing and sample collection as part of Cipher’s services to Exxaro Resources. The Late Permian coal measures in the Kalihari area of Botswana are being investigated for coalbed methane (CBM) potential. The coal deposits of both South Africa and Botswana (and, […]
It’s always surprising to be caught out by an assumption. In this case I was writing a first draft of a paper on the effects of rank change (that is, change in organic maturation) on a coalbed methane reservoir. The study area, known locally as the Pinang Dome, is located in Kalimantan (Borneo), Indonesia. […]
