f Reservoir Characterization of the Ardalin Field, an Upper Devonian Thrombolite Reef, Timan Pechora Basin, Northern Russia

Conoco and Archangelskgeologia (AG) have formed the joint venture Polar Lights to develop Ardalin Field in the Timan Pechora Basin of Russia. Ardalin Field is a combined structural/stratigraphic trap formed by carbonate build-up deposition from the Silurian to the Late Devonian. Drape of deeper water contemporaneous deposits, and subsequent nonbuildup sediments over the thick build-up create a seismically welldefined structure. Hydrocarbons are accumulated in the top of the structure in porous Famennian (Upper Devonian) limestones. The reservoir comprises interbedded microbial boundstones (thrombolites), peloidal/ skeletel grainstones, and microbial laminites.
