Abstract

Abstract The Cardium (Turonian-Coniacian) Carrot Creek “K” Pool (T 51–52, R 13W5) is a narrow, elongate, northwest-southeast trending conglomeratic reservoir unit. Detailed core and log analysis indicates that the reservoir consists of two lithostratigraphic units: an underlying, fine-grained regressive unit (with little or no reservoir quality), and an overlying conglomeratic transgressive unit (representing the main reservoir). The transgressive unit consists of matrix-supported and clast-supported conglomerate. Matrix-supported conglomerate are confined to the western (paleolandward) side of the “K” Pool area and are interpreted as braided-stream deposits associated with a conglomeratic distributary mouth-bar complex. Clast-supported conglomerate occur eastward (paleoseaward) of the matrix-supported conglomerates and are interpreted to have been deposited on an open-marine shoreface/beachface; they are the result of wave-reworking and redistribution of sediment material sourced principally from the distributary mouth-bar complex. Knowledge of lithofacies distribution within the Carrot Creek “K” Pool is essential to an understanding of reservoir quality distribution and prediction of permeability pathways within the reservoir. This can be of benefit in the design and implementation of pressure maintenance programs or enhanced recovery techniques.
