The best acreage usually represents a relatively small area of a total play. Highly variable production results from one well to the next are typical in resource play developments, and that variability offers proof that many conventional methods, from completion design to fracturing application, are not effective in unconventional reservoirs. That may seem obvious, but many operators continue to use methods designed for permeable matrix flow that shales simply do not support. The initial step toward accomplishing this objective is acknowledging that resource plays must be treated unconventionally. Improving well performance to increase per-well recovery rates by only a few percentage points would have enormous positive implications on development economics, and may not be that difficult if the mechanics of fluid flow and the stability of propped and unpropped fractures within these shales are better understood. Success of refracturing on wells that have suffered sharp production declines indicates that advances in the initial fracture stimulation are required.įiguring out how recoveries can be improved to flatten decline curves and add incremental production over the life cycles of horizontal wells in ultralow-permeability reservoirs is a complex and multifaceted issue, but the potential reward is substantial. The rapid declines are caused by flush production from the natural fractures, and slow recharge from the microfissures and the few larger pores in the matrix.

Related to these low recovery rates, both gas and liquids-rich shale production declines rapidly in shale formations, with production often declining by half or more of initial production rate within the first six to 12 months. Using standard drilling and completion approaches, recovery factors in unconventional liquids-rich formations tend to be measured in the single digits, or only a fraction of typical recovery rates during the primary production phase in conventional reservoirs. Production from tight oil and liquids-rich gas shales may double or even triple with purpose-engineered methods aimed squarely at the local geological characteristics and properties of the formation fluids.īut therein is the industry’s challenge.

HOUSTON–Even with the unprecedented and ongoing success of plays such as the Bakken, Eagle Ford, Marcellus and Wolfcamp, the industry has only scratched the surface of the tremendous potential of liquids-rich unconventional formations.
