Dimensional Orientation of Micrite Particles and Lithification in L-3 Carbonate Reservoir Rocks of Bombay High Oil Field, India

Thin bands of lithified biomicrites separate highly leached, poorly to semilithified biomicrite reservoir rocks of the L-3 zone of Bombay High Oil FIeld. Among many criteria suggested in literature as to the lithification of limernuds, percolation of carbonate ion bearing solutions principally across and secondarily along the bedding plane appears to account for most of the lime cement. This concept is tested by a dimensional orientation analysis of micrite particles. This indication suggested that Iithifying solutions have preferentially moved basically at right angles and secondarily parallel to the bedding plane.
