A detailed review of the current 139 offshore and onshore new E&P blocks of
Libya has been performed by utilising published well records, well logs,
stratigraphic sections, structural sections, and stratigraphic, geochemical,
tectonic and structural maps of Cyrenaica, Ghadames, Murzuq, Sirt, Tripolitania,
and offshore Basins of Libya. Due to the large number of parameters, and to
impartially assess, compare, and rank the E&P potentials of the blocks, one map
and, a set EXCELã| databases were compiled to summarise well data, exploration
records, and geological, geochemical, and tectonic parameters of the new blocks.
The first se of E&P databases summarises the drilling, engineering and
geological data per block
(31*139 data entries). An exploration risk equation
was modified to rank the relative E&P potential of the individual blocks, via
comparing the source, reservoirs, cap rocks, tectonics, remaining undrilled
anomalies, and exploration results of each
block
. Three sort variations of the
first database were generated in order to rank every one new
block
. The second
set of E&P databases lists drilling, engineering and geological data, status and
results of about 666 wells in all blocks (28*666 data entries). One sort
variation of the second database was generated to alphabetically list well data
per each
block
. Results indicate that database analysis can produce an impartial
ranking of the relative E&P potentialities of a large number of blocks, in
several basins with different stratigraphic, thermal and tectonic histories, and
tabulates and graphically illustrates the reasons for ranking the blocks, per
basin, and per several basins.
