GTW Colombia 2014: Expanding Unconventional Resources in Colombia with New Science – From Heavy Oil to Shale Gas/Shale Oil Opportunities

10-11 December 2014
Bogotá, D. C. , Colombia
Sponsored By:
Amerisur Resources PLC
Baker Hughes
Emerald Energy
Talisman Energy

Unconventional hydrocarbon resources from heavy oil and shale gas/shale oil represent some of the main components of the Colombian near-future portfolio which involves enormous reserves. Success requires the application of new scientific understanding, techniques, and technologies, as well as an understanding of how global analogues may provide useful information.

GTW Colombia 2014 offers a timely forum among experts and practitioners from geology, geophysics and engineering to review the nature of unconventional resources, the technology required to achieve efficient production, and even more, to address the environmental challenges implied.

Join the GTW Colombia 2014 discussion with leading operators in Latin America, North America and across the globe to expand the science of unconventional resources in Colombia. Build on lessons learned since GTW Colombia 2011. Develop new knowledge from lively discussions with experienced practitioners and researchers. Gain greater understanding by sharing first-hand experiences and best practices in applying geology, geophysics and engineering to the challenges of exploration, appraisal, development drilling, reservoir characterization and simulation, and advances in recovery processes.

The workshop will conclude with discussions in which lessons learned are applied to future endeavors. To facilitate the exchange of ideas, there will be no recorded presentations or publications released from this workshop without the express permission of the presenters and their companies. Participants will have many opportunities to network and to discuss with fellow practitioners.
