The Akaso Field [STOIIP 78 × 106 m3 (401 Million STB)] of The Eastern Niger Delta is separated from the large Cawthorne Channel field [STOIIP 208 × 106 m3 (1307 million STB)] by a major antithetic (counterregional) normal fault. In 1989, three-dime

Pseudo-anticlines and other structures in some calcretes of Botswana and South Africa

Autor: N. L. Watts

Publikováno v: Earth Surface Processes. 2:63-74

Deformation structures, within some Quaternary calcretes of Botswana and South Africa, have been classified into five types. Type 1 folds are small-scale ( 20 m), but low amplitude (< 1 m), anticlines in hardpan calcrete; structural evidence suggests

Quaternary pedogenic calcretes from the Kalahari (southern Africa): mineralogy, genesis and diagenesis

Autor: N. L. Watts

Publikováno v: Calcretes

The calcretes of the Kalahari are amongst the thickest in the world representing pedogenic episodes in a semi-arid climate during Pliocene to Recent times. The descriptive morphological terminology of Netterberg is used to describe the calcrete types

Theoretical Aspects of Cap-Rock and Fault Seals for Single- and Two-Phase Hydrocarbon Columns: ABSTRACT

Autor: N. L. Watts

Publikováno v: AAPG Bulletin. 69

Cap-rock seals can be divided genetically into those that fail by capillary leakage (membrane seals) and those that fail due to fracturing or wedging open of faults (hydraulic seals). A given membrane seal can trap a larger column of oil than gas at

Microfractures in Chalks of Albuskjell Field, Norwegian Sector, North Sea: Possible Origin and Distribution

Autor: N. L. Watts

Publikováno v: AAPG Bulletin. 67

Production data from many North Sea chalk fields have indicated moderate to considerable contribution to production from natural fractures. This paper illustrates a detailed study of natural fracturing in the Albuskjell field, where gas/condensate hy

Upper Cretaceous and lower Tertiary chalks of the Albuskjell area, North Sea: Deposition in a slope and a base-of-slope environment

Autor: N. L. Watts, J. F. Lapré, A. Ford, F. S. van Schijndel-Goester

Publikováno v: Geology. 8:217

Maastrichtian-Danian chalks of well 1/6-3 (Albuskjell structure, North Sea) contain large-scale allochthonous chalk units that were emplaced by slumping, debris flows, turbidity flows, and other bottom-traction processes in a slope and a base-of-slop
