Today I'll be discussing the process of discovering the giant Ring/Border field in British Columbia Canada using an integrated team approach to exploration problem solving.
Our exploration team consisted of a geologist, petrographer, log analyst, hydrodynamicist. engineer, landman, and support staff.
I would like to tell you about this group of professionals who each had to work together to understand and support a major play which had previously been missed. This play was identified in an area of modest well control where many wells previously had been logged, tested, cored, completed and even production tested. At the end of this talk I hope to convince you that a leap of faith had occurred on behalf of this group, a leap of faith that no one person could have taken alone—but that this exploration team did—together and turned a 5.0 BCF pool into a 1.0 TCF field.
The field area straddles the border between Northern British Columbia and Alberta (Figure 1). At the time of drilling the closest pipeline tie-in was 25 miles away across swampy muskeg. Canadian Hunter was drilling a well for a deep Devonian gas target. The Devonian target did not materialize but an uphole zone was thought to have marginal potential.
The clock (Figure 2) will keep track of our progress. Tune zero was the drilling of the deep Devonian dryhole. This is a story about that marginal uphole zone.
The standard information source, PIX data, described a few uneconomic gas shows. From the initial show map
