Challenges in Reserves Estimate for
Tight/Unconventional Reservoirs

Saad Ibrahim, P. Engineer, President Petro Management Group

Interactive Workshops: June 8, 2017 , Calgary AB

Agenda

As the oil industry in North America is shifting fast into the exploitation of tight and
unconventional reservoirs; with permeability ranging from Micro to Nano Darcy,
reserves estimate is becoming a challenging task. Reserves definitions; such as,
Stimulated Reservoir Volume (SRV) and Contacted Reservoir Volume (CRV) will be
discussed. When all methods fail, we tend to seek help from the decline analysis
technique. Decline analysis and its derivative; such as the Power Law Loss-Ratio
Method, are simple and fast to use being empirical, however, they do have some
limitations. Rate Transient Analysis (RTA) techniques, have merits, as no long well
shut-ins are required. More advance methods using numerical techniques can produce
more reliable reserve estimates and can deal with complex reservoirs and
heterogeneities. Several case studies will be presented to demonstrate the various
techniques.

1. Why reserves estimate is challenging for tight/unconventional reservoirs?
2. Conventional methods for estimating reserves
3. Methods used for tight/unconventional reserves estimate
4. Case studies
Challended in Reserves Est for MFHW2

 

 

 

 

 

 

 

Typically this L&L starts at 11:30 am (complimentary lunch is offered by PMG) and the
technical presentation usually runs from 11:40 am until 12:50 noon, leaving 10 minutes
for questions at the end.
