“…Significant research has been done on lower Upper Cretaceous sandstone units since hydrocarbon production boomed in western North America in the 1960s (MacKenzie and Poole, 1962;Haun, 1963;MacKenzie, 1963;Harms, 1966;Exum and Harms, 1968;Currie, 1978;Weimer, 1984;Merewether and Cobban, 1986;Mateer, 1987;Weimer et al, 1988;Dolson et al, 1991;Leckie and Singh, 1991;Dyman et al, 1994;Hamilton, 1994;Pattison and Walker, 1994;Oldham, 1996;MacEachern et al, 1998;Scott et al, 1998;Brenner et al, 2000;Graham, 2000;Holbrook, 2001;Scott et al, 2001Scott et al, , 2004Higley et al, 2003;Joeckel et al, 2005;Kirschbaum and Roberts, 2005;Holbrook et al, 2006;Currie et al, 2008;Oboh-Ikuenobe et al, 2008;Koch and Brenner, 2009). However, stratigraphic and sedimentologic models for low-accommodation settings in this region have improved significantly since a lot of the research was published (Graham, 2000;Holbrook, 2001;Holbrook et al, 2006;ObohIkuenobe et al, 2008); thus, in some cases, a reassessment of the units is timely.…”
