5th EAGE Passive Seismic Workshop2

Workshop Format

Compared to other years the format of the workshop has been changed in order to facilitate the generation of tan-gible outcomes in the form of recommendations for future work through the interaction of operators, service providers and academia under a single forum. Each session will intro-duce the topic with invited keynote speakers followed by a facilitated discussion of some very specific related questions in smaller workgroups. The results of these discussions will be presented and integrated to all participants.

Breakout Sessions - Workplan

Session 1: Induced SeismicityA. Fundamentals1. How to discriminate between natural, induced and

triggered seismicity? Which parameters of microseismicity should be studied to understand differences between natural, induced and triggered seismicity?

2. Can we set up a predictive induced seismicity model and validate it?

3. What are the major obstacles in investigating the interactions between induced seismicity properties, geomechanics and exploitation, how we can mitigate them?

4. How to use microseismicity to infer the space time evolution of the reservoir? Can we estimate the proportion of cross-triggering between microearthquakes with respect to seismicity induced by slow forcing (pore pressure or creep on large fractures)?

5. What can we learn from (induced) microseismicity that we can use for larger induced seismicity?

B. Application1. Do we really need new processing techniques or sensor

systems?2. What are the main open questions on the end users side?3. In which aspects do case studies of induced seismicity differ?4. What is the accuracy of detection and source parameters

estimation?5. What are the advantages/disadvantages of new sensor

systems, e.g. fully fibre-optics, DAS, broadband sensors? Is there a need for low frequency sensors at depths such as strainmeters or tiltmeters?

6. Can OBC cables really be used to record microseismicity in deep-seated reservoirs?

C. Implementation1. How should responsibilities be assigned in case of damage?

Is there a need for discrimination between induced and triggered seismicity (consequences for regulation)?

2. How to balance public acceptance and profit (cp. to local NIMBY issues vs. global warming)?

3. What information can we give to managers and regulatory authorities to inform decision making in balancing any identified risk of induced seismicity with economic reward?

4. Does transparency help or hinder the process of rational risk assessment?

5. How can we assess and improve the estimation of the damaging potential of triggered/induced earthquakes?

6. How to designing a ‘smooth’ exploitation strategy that is not causing large magnitude earthquakes?

7. How can academia and industry co-operate?8. Who should own the collected data?

Session 2: Fracture MechanicsA. Fundamentals1. Do moment tensors represent the process sufficiently?2. Can we see tensile microseismic events?3. What do LPLD events indicate?4. Is any microseismic attribute a close proxy to production?5. How is microseismic data integrated into Fracture models?

B. Application1. Can we predict Fracture linkage (wet/dry fracture)2. Integration with other methods (Geomechanics, x-well,VSP,

EM, tilt, Lab, DAS)?3. What do microseismic events tell us about changes in

reservoir properties?4. What can we learn from ResEng/Geologists?5. What interpretations can be considered validated? What

interpretations are more speculative?

C. Implementation1. What can we learn for re-fracking old wells?2. What is Stimulated Reservoir Volume?3. How do we have to change our methods/displays/

vocabulary to best reach decision makers?4. How do we calculate and communicate uncertainty?5. What microseismic methods/tools/attributes can be used to

characterize the reservoir permeability changes, e.g. DFNs, TFI, r-t, effective models?

Session 3: Integrated InterpretationA. Fundamentals1. Microseismic and hydraulic fracture geometry; what we

can and cannot do with microseismic2. Microseismic and well productivity; what we can and

cannot do with microseismic3. What data is necessary/valuable to validate and constrain

certain interpretations of microseismic data?4. How do we measure success of integrated interpretation?5. Do gas filled formation and oil filled formations show the

same microseismic signatures?

B. Application1. What decisions can be influenced by the results of

microseismic data analysis?2. Can we use seismic attributes to predict productive SRV?3. How to determine the productive network?

C. Implementation1. How does integration happen within the operators?2. How can there be a better integration of results between

operators, service companies and academia?3. How do we promote cross-discipline interpretations?

Sunday 28 September 2014Icebreaker Reception 18:00-20:00 hrsDelegates are invited to join us on the River Lounge Terrace overlooking the River Targus, at Myriad by SANA for the ice-breaker reception.

Tuesday 30 September 2014Workshop DinnerThe workshop dinner will be held at Restaurant Kais, which is housed in a late XIX century old warehouse by the riverside which was used to generate energy for Portuguese trams that still work today. The warehouse was fully recovered and is now one of the most beautiful restaurants in the city.

Wednesday 1 October 2014Old Quarters of Lisbon Tour – kindly sponsored by

Discover the old Lisbon downtown, its old quarters and unique and colorful architecture, dating from the 18th cen-tury, with its facades covered with glazed tile. We begin at Lisbon’s Cathedral, where we will start a short walk towards Portas do Sol Square. From there we embark on a small walk-ing promenade through the winding streets of the medieval borough of Alfama before climbing uphill to the gates of St. Jorge’s Castle.

Closing Cocktails – kindly sponsored by Casa do LeãoWe will close the workshop with a drinks reception at Casa do Leao, set within the grounds of St Jorge’s Castle. From the ter-race we will enjoy a magnificent view over the city of Lisbon and the Tagus River.
