Summary:The Red River formation has been subdivided into four distinct zones A, B, C and D, based on depositional sequences and log characteristics of the sediments. Zones A,B and C are a series of deposits formed during three distinct upward-shoaling carbonate-evaporite hemicycles. Generally the sediments in each hemicycle are limestone, dolomite and anhydrite in ascending order. Each cycle started with open-marine conditions and became increasingly evaporitic, with increasingly restricted circulation. Rapid incursion of normal marine sea-water brought a return to open-marine conditions and the abrupt beginning of the next hemicycle. All four zones are productive of hydrocarbons. Two different styles of diagenesis have affected the different production zones. The depositional environments of the A,B and C dolomites are similar but are distinctly different from that of the D zone dolomite. [J.M.H.]
