Gas Detection In Upper Cretaceous Formations

Journal of Canadian Petroleum Technology, 1986
Abstract Hydrocarbon resource companies in the Lloydminster heavy oil region have experienced problems with unwanted gas flows to surface outside production and surface casings. Locating the source of these flows prior to attempting to shut the gas off has proved troublesome. Gas shut-off attempts have therefore had

Upper Cretaceous Bolivinoides Guide Forms

Micropaleontology, 1958
"The development of the series Bolivinoides strigillata- decorata-australis-gigantea in the upper Cretaceous of Belgium is followed. In a nearly continuous sequence of formations, the group is found to increase the number of pustules on the last-formed sutures from two to nine. This continuous increase can be used as a stratigraphic tool in working out

Iterative progenesis in Upper Cretaceous ammonites

Paleobiology, 1989
Pteroscaphites are small, rare species of scaphitid ammonites from the Upper Cretaceous (Turonian-Santonian) of the Western Interior of North America. Their evolution appears to parallel that of the larger species ofScaphitesorClioscaphites, with which they co-occur.
