... Tertiary rocks are predominantly freshwater and coal bearing. Younger rocks are dominantly marine, and include considerable thickness of mudstone and limestone. Oil seepages along the West basin are associated almost entirely with the lower Tertiary coal measures. In the Taranaki basin a small oil field...

.... The production of this field in 1950 was 488,000 barrels. These two fields represent the variation in mode of occurrence of Spraberry oil: Tex Harvey is a permeability trap with no structure apparent, and the Spraberry pool is a sharp anticlinal feature probably caused by draping over a small non-productive high...

Wellman ABSTRACT Twenty-nine core and seven cuttings samples were collected from two boreholes penetrating the Middle Ordovician Hawaz Formation in the Murzuq Basin, south-west Libya. The samples were palynologically analysed in order to determine age and depositional...

The steel casings of abandoned wells eventually develop leaks, which if not properly plugged, can allow pollutants to reach...

There is considerable geological evidence (Dubertret, 1932; Quennell, 1958; Freund, 1965; and De Sitter 1962) that transeurrent movement has occurred...
