... Abstract This paper presents construction and validation of a reservoir model for the Niobrara and Codell Formations in Wattenberg Field of the Denver-Julesburg Basin. Characterization of Niobrara-Codell system is challenging because of the geologic complexity resulting from the presence...

... without surrounding water wells to detect migration, based on well construction type. Since 1970, the Wattenberg Field in Colorado has a large number of oil and gas wells drilled. These wells are interspaced tightly with agricultural and urban development from the nearby Denver Metropolitan area...

... reservoir data that is commonly available. We successfully confronted our method to a case study in the Wattenberg field using data from 300 Codell tight gas wells. The performance of refracturing treatments has been observed to be highly variable in the Wattenberg field (Colorado) with some wells...

... the existence of refracture reorientation in the Codell formation. The performance of refracturing treatments has been observed to be highly variable in the Wattenberg field (Colorado) with some wells underperforming while others are restored to initial production rates. Historical production from neighboring...

... Many carbonate reservoir related paradigms have failed to find their usefulness at the Wattenberg field. For example, in typical carbonate formation natural fracture resulted from geological structure is a critical factor governing hydrocarbon production. At the Wattenberg field, many wells...

... Abstract Natural fracture swarms are usually a critical factor governing hydrocarbon production from the carbonate formation. In a low permeability carbonate reservoir at the Wattenberg field, the author has observed that natural fracture swarms are more likely to exist near such geology...

...Introduction The J Sand sandstone is a typical tight gas formation, continuously covering the Wattenberg field in the Denver-Julesburg basin ( Fig 1 ). Intensive digenesis effects have substantially reduced its permeability to sub milli-Darcy magnitude. Combined effects of low permeability...

... The objective of surface tiltmeter mapping on this project was to determine the fracture orientation of initial fracture treatments and refracture treatments of the Codell formation in the Wattenberg Field. The primary focus of the project was to determine if refracture reorientation was playing...

... Abstract Since the early 1970s, fracturing fluid systems utilized in the J-Sand treatments in the Wattenberg field have ranged from poly emulsion to cross link gels with and without an inert gas phase (e.g. N 2 , CO 2 ). Current treatments typically consist of large proppant volumes...

... Abstract The J Sand formation is a main pay zone in the extensively developed Wattenberg field of Colorado. Until recently, operators deemed the reservoir in the northeast part of this field uneconomical due to significant production of formation water in this low permeability and sub-pressured...

... off due to excessive production and reducing the number of wells logged off due to excessive fluid buildup. A review of the benefits derived from this system are enumerated and the impact on field operations are discussed. Introduction The Wattenberg field is located about 25 miles north of Denver...
