Unlocking Alberta’s Carbonate Reservoirs

16 – 17 September 2014

Banff, Alberta, Canada | The Rimrock Resort Hotel

Technical Agenda

Tuesday, 16 September, 0800-0930

Session 1: Past Pilot Activity in the Grosmont - Part 1

Session Chairpersons: Ron Sawatzky, Eugene Dembicki

Unocal was a pioneer in exploring and piloting recovery methods from the Grosmont Formation.  In 1973, they drilled their first Grosmont exploratory well and were subsequently encouraged to follow up their exploration efforts with a series of steam based pilots at Chipewyan River and Buffalo Creek.  From 1979-1988, Unocal partnered with AOSTRA (Alberta Oil Sands Technology and Research Authority) and implemented additional pilots at Buffalo Creek, McLean, Orchid, and Saleski.  In 1984, Chevron joined the pioneering activity in the Grosmont by operating a pilot at Algar in partnership with AOSTRA.   This session revisits the past pilot results with a modern interpretation of the data.

1000–1130

SESSION 3: Heavy Oil Experience Outside Alberta

Session Chairpersons: Daniel Yang, Kumar Mridal, Johan VanDorp  

Several enhanced oil recovery (EOR) pilots and projects in heavy oil carbonate reservoirs are currently ongoing or have been conducted in the past around the world (including Middle East, Turkey, Russia, Egypt, and Republic of Congo).  This session focusses on sharing results, learning’s, and experiences from carbonate heavy oil EOR field projects outside of the Alberta bitumen reservoirs.

1500-1630

SESSION 4: Geology and Resource Characterization of Bitumen Carbonates

Session Chairpersons: Jen Russel, Mark Mallamo

The bitumen carbonate reservoirs in Alberta were buried, tilted, uplifted, and exposed at the surface – resulting in fractured and karsted carbonate. The porosity network of carbonate rocks differs from the long-producing and better-studied clastic bitumen reservoirs and as a result different methods must be employed to measure and describe the reservoir. The porosity, permeability and saturation of fractures and vugs are challenging to measure in core and yet their properties dominate the fluid movement in the reservoir. Modern petrophysical logs and advanced seismic processing become important datasets to combine with the routine analysis to define karst-related features. This session will look at the methods used by petroleum geologists working on bitumen carbonate evaluations and present geological summaries of Grosmont, Ireton, Nisku, Leduc formations.

Wednesday, 17 September, 0800–0930

SESSION 5: Recent Grosmont Bitumen Extraction Pilots - Part 1

Session Chairpersons: Kent Barrett, Jian-Yang Yuan

Discussions in these two sessions will focus on the performances of recent pilot tests including the Laricina/Osum Saleski Pilot

1000–1130

SESSION 6: Recent Grosmont Bitumen Extraction Pilots - Part 2

Session Chairpersons: Kent Barrett, Jian-Yang Yuan

Discussions in these two sessions will focus on the performances of recent pilot tests including LEL/Osum Salaski Pilot (additional, pending on how we secure talks from projects, Shell, Sunshine, etc.)

1300–1430

SESSION 7: Drilling, Completions & Operations

Session Chairperson: Bruce Thornton, Steve Brand

Discussions in this session will provide insights with Drilling, Completions and Operational experience in the Carbonates including the Laricina/Osum Saleski Pilot. Presentations will include some of the challenges faced including lost circulation, cementing practices, completion and well designs.

1500–1630

SESSION 8: Recovery Mechanisms and Simulation

Session Chairpersons: Bruce Roberts, Amin Badamchi Zadeh, Pingke Li

This session will focus on the mechanisms of bitumen recovery from heterogeneous, fractured carbonates and the modeling of these processes to aid in the design of optimal recovery schemes.
