The accumulation covers a large area and is a potential giant accumulation. Recent drilling success by several operators indicates that productive reservoir conditions exist in the southern PRB (Figure 1). In this area, the Niobrara Formation consists of ...The organic-rich carbonates are similar to the unconventional fluid oil and biogenic gas-producing Niobrara Formation in North America. A workflow for de-risking productivity of an unconventional play is in part based on our examination of the S1 · 100/total organic carbon (TOC) ratios, which represent potentially producible oil, where S1 is ...
