Amal Field, Libya: ABSTRACT

[N(CH3)4]4H12Ge9O26.14H2O

“…Bridging O atoms link the central Ge atom to all the cube vertices. Previous studies concerning Ge complexes have shown that the valence shell can be expanded beyond the limits permitted by the filled-octet rule (Mehrotra & Chandra, 1963;Yoder & Zukerman, 1967;Sau & Holmes, 1981;Day et al, 1982;Gurkova et al, 1984;Eujen et al, 1986;Sau et al, 1986;Breliere et al, 1988;Mizuta et al, 1989;Lazraq et al, 1990;Cerveau et al, 1991;Roberts & Fitch, 1991;Chiang et al, 1992Chiang et al, , 1993Chiang et al, , 1995Jones et al, 1992;Cascales et al, 1998;Li et al, 1998). The title compound gives further evidence of this with Ge in four-, five-and sixfold geometry.…”

Three‐Dimensional Structural Modelling and Source Rock Evaluation of the Quseir Formation in the Komombo Basin, Egypt

“…Tissot and Welte (1984) considered that %R o is the most powerful maturation-measuring tool. Moreover, %R o is not dependent on or vulnerable to kerogen and lithology type, or contamination, as with many other maturation parameters (Roberts, 1970;Fig. 12.…”

Review of the petroleum geology of the western part of the Sirt Basin, Libya

“…Traps. Several different trapping mechanisms have been described from the Sirt Basin (e.g., Fraser, 1967;Roberts, 1970;Sandford, 1970;Williams, 1972;Brady et al, 1980: Clifford et al, 1980. Also, comprehensive field summaries have been published by Thomas (1985a) and Hallett (2002), and it is well known that hydrocarbon traps can be classified either as structural, stratigraphic or combination of both.…”

“…Characteristic features of the oil fields previously discovered in the Sirt Basin (Fraser, 1967;Roberts, 1970;Sandford, 1970;Williams, 1972;Clifford et al, 1980;Brady et al, 1980) that are largely still producing, are referred to because they can provide analogues for further discoveries. It is with this purpose in mind that I also point out the oil discoveries in the Sirt Basin, even though they are located beyond the scope of the study area.…”
