Abstract
Depositional Facies and Porosity Development of an Upper Pennsylvanian Algal Mound Reservoir, South Dagger Draw, Eddy County, New Mexico
Abstract
The Upper Pennsylvanian in South Dagger Draw produces from the Cisco (Virgilian) and Canyon (Missourian) formations. The depositional environment for the Dagger Draw area is an encrusted algal mound complex. Reservoir quality is predominantly developed in mound facies algal boundstones. Intermound and off-mound facies are also productive from fusulinid grainstone-wackestone, and crinoidal grainstone-packstone. Reservoir baffles/barriers are present as mudstones, siltstones, and terrigenous shales. Depositional facies appear to exert the primary control on pore type and distribution; burial diagenesis exerts a secondary control on porosity development. Reservoir facies are dolomite and are largely productive from vuggy and intercrystalline porosity. Porosity in limestone intervals is generally moldic and volumetrically insignificant.
