What does Pryme consider to be the main differences between the search for hydrocarbons in Texas and Louisiana?
Louisiana geology, when compared with Texas, generally has similar stratigraphy (layers of sedimentary beds and their overall sequence) because it all started with the birth of the Gulf of Mexico millions of years ago. In addition, the Gulf Coast of Texas is in the same vast Gulf Coast embayment that extends from the Texas-Mexico border to the southern tip of Florida. The lithology however (the composition of the sedimentary beds – whether sandstone, shale, limestone or coal) differs quite a bit in a quite a few places in both states. In Louisiana, the lithology and deposition of these beds in some parts of the state has been vastly affected by rivers such as the Mississippi and the advance and receding of salt water bodies. For example, our LaSalle Parish, Louisiana project has as its primary objective the “Middle Wilcox” which is nothing more than very old Mississippi River delta. Consequently, the sandstones and shales we drill through there are relatively soft and unconsolidated. I
