Sustained low gas prices, dynamic oil and gas markets and successful exploitation of tight oil opportunities have drastically altered the Rocky Mountains region. This once gas-dominant area has seen activity decline in many basins but has realised success in the Williston and Denver-Julesburg basins where spend, production and remaining value continue to grow. A keychallenge for operators will be to continue to drive down costs and improve productivity, as sustained low commodity prices will act as a constraint for future success. This country report gives an overview of the key upstream issues for the Rocky Mountains region. If you’re interested in identifying and assessing upstream investment and expansion opportunities, this upstream summary is your definitive commercial guide. Potential investors, governments and companies in the oil and gas sector can use it to gain a better understanding of the critical issues for development opportunities in the region.
