... In unconventional reservoirs such as tight gas sandstones and organic-rich mudrocks, sweet-spot analysis becomes significantly more complicated. Economic recovery of hydrocarbons from these unconventional reservoirs typically requires large hydraulic fracturing treatments. Such large-scale...

... Abstract Horizontal wells with hydraulic fractures enable economical hydrocarbon extraction from unconventional reservoirs, and the associated transient production data is a reliable source for reservoir characterization. However, the complicated convolution of rate-pressure-time history leads...

NPV of the cash flows and IRR are calculated for the given scenarios in this paper. Profitability is gauged based on whether the values are positive or negative for the resulting NPV calculations...

...Reservoir Flow Model for Unconventional Resources Reservoir modeling for unconventional resources is quite difficult compared to conventional reservoirs. Because of horizontal wells and hydraulic fracturing treatments, the nature of unconventional reservoirs differs from conventional...

... Abstract It is estimated that only one third of the remaining worldwide oil and gas reserves are conventional, the remainder being in unconventional reservoirs whose evaluation requires appropriate measurements delivered in a cost-effective way. In the case of shales and other tight reservoirs...
