ABSTRACT: Rank, Potential, Undeveloped Fields, and Discoveries of the 137 New E&P Blocks of Onshore and Offshore Libya

A review of the 137 new (10-5-2000) offshore and onshore E&P blocks of Libya utilised 500 well records, numerous well logs, stratigraphic sections, structural sections, and stratigraphic, geochemical, tectonic and structural maps of Cyrenaica, Ghadames, Murzuk, 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 137 blocks, one map and, a set EXCELc databases were compiled to summarise well data, exploration records, and geological, geochemical, and tectonic parameters of the 137 new blocks:

A new well location map of the 137 Blocks (Scale 1/2500) was drafted to illustrate the exploration or production status of the wells within the blocks.

The first E&P database summarises the drilling, engineering and geological data per block (31*137 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 of the new 137 blocks, and to produce 30 charts illustrating:

The relative E&P ranks of the blocks of every basin.

The relative E&P rank of the blocks for all basins in Libya.

The relative size and distribution of the proven, probable and possible discovered hydrocarbon reserves of all blocks.

The second E&P database lists drilling, engineering and geological data, status and results of the 500 wells in all blocks (28*500 data entries). One sort variation of the second database was generated to alphabetically list wells per each block.
