Special thanks go to Bill Schmidt for seismic interpretation, to Ray Mitchell for his insight into the sedimentology and diagenesis of the reservoir and for most of the core and thin-section photographs in this manuscript, to Eric Michael for his geochemical contribution, and to Bill Clopine for his guidance in biostratigraphic studies. At Arkhangelskgeoldobycha, Yury Deulin, Ludmilla Plehotkina, and many of the AGD staff members have worked on helping us understand this field and its regional setting. Laboratory help was provided by Galina Tarasova and her staff at AGD. Elena Musafirova of the Timan-Pechora Scientific Research Center in Ukhta provided all the fusulinid identification and Timan-Pechora Basin fusulinid regional understanding. Thanks go to these and the many other people involved with this field over the years.
