Submission of an Abstract All authors that want to present a Technical Paper in this Symposium must submit an Abstract, with a short summary of the paper and its main conclusions, following the LINK in this page and completing the data required in that link. The deadline for the Call for Papers is March 6th, 2018. The Abstract should be classified by the author in one of the following Symposium Topics: 1. Well Construction Practices 2. Unconventional Reservoirs Engineering 3. Characterization of tight and shale reservoirs 4. Well Completion and Stimulation Optimization 5. Well Testing 6. Hydrocarbon recovery increase 7. Technological advances 8. Case Studies 9. Environmental Aspects Note: "Other suggested topics connected to the above mentioned ones are those related with Unconventional Hydrcarbon Production like: Choke Management and Artificial Lift Systems in Horizontal Multifractured Wells". The interest of this Symposium is focused in Tight Gas, Shale Oil and Shale Gas reservoirs. Other disciplines as "Heavy Oil Recovery", "Coal Bed Methane", "Methane Hydrates", etc., that might be considered as unconventional hydrocarbon resources, are not included among the topics for this specific event.
