Greater Green River Basin production improvement project, Phase 1: Site characterization report
Several tight, naturally-fractured, gas-productive formations in the Greater Green River Basin (GGRB) in Wyoming have been exploited using conventional vertical well technology. Typically, hydraulic fracture treatments must be performed in completing these wells to increase gas production rates to economic levels. However, with the maturation of horizontal drilling technology hydraulic fracture treatments may not be the most effective method for improving gas production from these tight reservoirs. Two of the most prolific tight gas reservoirs in the Green River Basin, the Frontier and the Mesaverde, are candidates for the application of horizontal well completion technology. The objective of the proposed project is to apply the DOE`s technical concept to the Second Frontier Formation on the western flank of the Rock Springs Uplift. Previous industry attempts to produce in commercial quantities from the Second Frontier Formation have been hampered by lack of understanding of both the in-situ natural fracture system and lack of adequate stimulation treatments. The proposed technical approach involves drilling a vertical characterization well to the Second Frontier Formation at a depth of approximately 16,000 ft. from a site located about 18 miles northwest of Rock Springs, Wyoming. Logging, coring, and well testing information from the vertical well will be used to design a hydraulic fracturing treatment and to assess the resulting production performance. Data from the vertical drilling phase will be used to design a 2,500 to 3,000-ft lateral wellbore which will be kicked off from the vertical hole and extend into the blanket marine sandstone bench of the Second Frontier Formation. The trajectory of this wellbore will be designed to intersect the maximum number of natural fractures to maximize production rates. Production testing of the resulting completion will provide an assessment of reserve potential related to horizontal lateral completions
A Taxonomy of SME E-Commerce Platforms Derived from a MarketLevel Analysis
Copyright © 2018 Christopher P. Holland and Manuela Gutiérrez-Leefmans.Published with license by Taylor & Francis. Small and medium-size enterprises (SMEs) constitute a large and important sector of the U.S. and U.K. economies and e-commerce platforms have evolved that are designed specifically to help small business owners and entrepreneurs. Despite the popularity and importance of these digital platforms, there is a paucity of research in this area. This article contributes to theory by being the first study to map out the competitive landscape of SME e-commerce platforms in two markets using a theoretical framework and analysis that is based on business model and strategic group theories. In total, 144 platforms were analyzed using an online panel data methodology, which identified 32 leading SME e-commerce platforms in the UK and United States. These leading platforms were analyzed at the market level using cluster analysis based on strategic group theory and website content analysis. A taxonomy is proposed based on theoretical constructs derived from business model theory: value proposition, Web 2.0 sophistication, and revenue model. Five distinctive strategic groups are identified: information laggards, basic networking, advanced networking, advanced networking mature, and social media markets. The study further outlines managerial implications for SMEs, SME e-commerce platform providers, and external sponsors of the platforms—predominantly government organizations and banks
