New-Frontier Reservoirs I
With the current changes in the industry, are we seeing the demise of unconventional reservoir development? Let us review several recent industry indicators.
Numerous 2016 published outlooks still forecast unconventional production to increase from 10% in 2016 to greater than 25% by 2035 from sustained growth in North America and China. By 2040, it is also expected that unconventional supplies will account for nearly 90% of North American gas production. This increase in unconventional-gas demand is expected to be driven by a fundamental global requirement for energy in the medium term that is affordable, abundant, clean, and available.
Are these forecasts still realistic in the shorter term, when we are faced with a low oil price? I would argue that they are still realistic because, although the industry is contracting, it is quite clear that companies are rapidly adapting to the oil-price drop. Apache, for example, is quoting that unconventional-well costs have reduced by 45% below their 2014 average, with 50% of these savings as a result of new technologies. Shell is highlighting similar well-cost reductions of 30% year on year. The cost savings arise from many areas. These include new drill-bit technology; replacing diesel with cleaner and less-expensive natural gas for rig fuel; pad drilling; fracture-stimulation optimization, including fewer and smaller fracture stimulations; alternative proppant; and recycling more completion fluid. In other regions of the world, where unconventionals are more immature, such as Argentina, Saudi Arabia, and China, appraisal and exploration also continue for the most-attractive unconventional plays.
So, are we seeing the demise of unconventional developments? No, clearly not. The key frontiers or challenges for the unconventional industry to grow are technological, geographical, commercial, and geological. This feature highlights some of these key frontiers being explored around the world to ensure that the unconventional industry does not just survive but thrives.
