Carbonate reservoirs is one of the most important fields of oil-gas exploration and production as it accounts for 52% of the world's proven oil reserves and 60% of the world's oil production. Yet, we as an industry still do not understand the flow behavior and thus the expected ultimate recovery because of the intricate combination of pore, fracture-pore and fracture-cavity elements. Various field studies have demonstrated that such heterogeneous rock fabric defies Darcy and known flow behavior concepts and theories. It is well established that the characteristics of fracture-cavity reservoirs are very different from that of pore and fracture-pore reservoirs. Karst caves, fractures and dissolved pores make up the reservoir space with the feature of discontinuity in fracture cavity system. There are no efficient methods and techniques yet to identify and describe this kind of reservoir bodies so that one could eliminate the rapid decline in production associated with such reservoirs.
The planned Workshop is to take a closer look as to how one can first characterize the heterogeneous fabric of these fractured carbonates including vugs and karsts. The Workshop will begin with sessions that brings the following disciplines together to understand the flow behavior: 3D Geophysics and Geology, Petrophysics, Geomechanics, Geochemistry, Well Logging, Core testing and Dynamic Well Testing including Tracers. Specifics requirements for oil and gas reservoirs individually will be addressed before building the 3D static and dynamic models. Such modeling will need to be combined with various seismic attributes, litho-facies and relevant data gathered to identify “sweet spots” for well placement. Well drilling and trajectory should be guided by the sweet spot locations as well as the required effective completion and stimulation tool placement. Completion and stimulation design to exploit the sweet spots will require formulation of an effective field development plan. As production ensues, present reservoir characterization understanding will then be focused towards field and well rejuvenation and long term production for enhanced recovery.
This workshop is designed for all subsurface disciplines:
This workshop consisting of 2½ days of informal sessions, with a number of short presentations and group discussions, will be conducted in dual languages – Chinese and English. Simultaneous translation will be used during the workshop.
In keeping with workshop objectives and the SPE mission, excessive commercialism in posters or presentations will not be permitted. Company logos must be limited to the title slide and used only to indicate the affiliation of the presenter and others involved in the work.
All attendees will receive an attendance certificate attesting to their participation at the Workshop. This certificate will be provided in exchange for a completed questionnaire on-site.
This Workshop qualifies for SPE Continuing Education Units (CEU) at the rate of 0.1 CEU per hour.
General and detailed accommodation information will be forwarded to registrants with the attendee package prior to the scheduled Workshop by April 2014.
Delegates are advised to book their international/ domestic airline tickets early from their country/city to Nanjing, China. Delegates travelling to China must be in possession of a passport valid for at least six (6) months on arrival, and must hold a visa issued by the appropriate Chinese officials prior to departure from your home country. Official invitations to apply for Chinese visas are available from the Society of Petroleum Engineers. Please check with your travel agent or the China Embassy on regulations relating to visa before your departure.
Casual clothing is recommended. The workshop atmosphere is informal.
