... successes and shortcomings of unconventional plays. A case study of the Wattenberg field will be presented in this session, demonstrating why public data cannot be used in its raw format and the exponential value gained from a cross-discipline analytical process. Within the field, four geological horizons...

.... The Niobrara is subdivided into two members: Smoky Hill and Fort Hays Limestone. The Smoky Hill is informally divided into A, B, C intervals in descending order. The chalks are separated by marl intervals. Dramatic thickness changes occur in the chalk and marl units in Wattenberg Field. Thickness variations...

... Abstract The Upper Cretaceous Codell Sandstone is a major pay in the giant Wattenberg Field of the Denver Basin. Vertical well completions in the Codell date back to 1981 and were hydraulic fracture stimulated. The vertical wells also have a history of successful hydraulic refracturing. New...

... Summary ConocoPhillips built its position in the D-J Basin Niobrara play between 2010 and 2012 with current leasehold of approximately 130,000 net acres south east of Denver. Envisaged as a new play extension to Wattenberg Field, based on a thermal anomaly in Arapahoe County, early production...

... The Codell Sandstone is a low-resistivity, low-contrast pay in parts of the northern Denver Basin. The area of new oil and gas production is in the deeper part of the basin between the Silo and Wattenberg fields of Wyoming and Colorado, respectively. Thickness of the Codell averages 15 to 20 ft...

... Greeley, Colorado is situated right in the heart of the DJ Basin's Wattenberg Field, in what is referred to as the " Sweetest of the Sweet Spots" for hydrocarbon production from Niobrara chalks and the Codell sandstone. While horizontal drilling has been very active all around the city...

.... In this study, we use natural gas stable isotopes and water quality data, cataloged by the COGCC, to evaluate methane sources in the Wattenberg field of the Denver-Julesburg basin. We focused on 112 out of 897 (12%) groundwater samples that exhibited elevated methane concentrations (>1mg L-1). Within...

... Abstract The Niobrara is one of nine horizons that are productive in the giant Wattenberg Field area (GWA) of Colorado. GWA covers approximately 3200 square miles. The field was discovered in 1970 (J Sandstone) and first significant Niobrara production was established in 1976 from vertical...

... Summary The Upper Cretaceous Codell and Niobrara formations are primary targets in the Wattenberg field (Figure 1) of the Denver-Julesberg basin in northwest Colorado. Although initial discovery of producible hydrocarbons in the Codell occurred in 1955, it was not until the early 1980s when...
