... in the DJ Basin, whereas half are located in the Wattenberg Field (marked by the green dashed curve). This makes DJ Basin, especially the Wattenberg field, a good target for carbon storage. The stacked formations of oil/gas reservoirs and saline aquifers in the DJ Basin are potential CO 2 storage...

... 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...

... 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. This provides a setting...

... 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...

... When it comes to carbonate, natural fracture is usually considered the primary factor that affect the well performance. Similar observations have been made at the Wattenberg field. The author has observed that in wells where the Niobrara formation has been penetrated by faults, FMI logs usually...

...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...

... Abstract This paper reports on a study conducted to measure the orientation of fractures created during initial fracture and refracture treatments in the Codell formation of the Wattenberg Field, Colorado. The Codell is a thin, low permeability sandstone that is laterally continuous across...

... fluctuated due to the economics of the individual operator at the time. 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...

... According to Colorado state information databases, initial development of the J Sand in the northeast Wattenberg field began in 1970. One well was developed in 1973 with 5 added in the early 1980's. The well drilled in 1970 was fracture treated with an 18,000 pound proppant treatment. This well...

... 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...
