japex drill reports, page-7

Japex maybe trying to avoid formation damage that GGX encountered last year.

David Munns says he had been talking to adjoining operators about technical knowledge learnt from their Nuevo Malolos well.

This is close to results that Japex would be looking for:

THE MALOLOS PROSPECT

Malolos 1 was drilled in 1960 to a total depth of 2749 metres with the principal objective to test for oil. 9 zones exhibited significant shows of hydrocarbons. Analysis of the well by the Company’s engineer reveals that there are at least three potential gas production zones and one oil production zone. The most significant hydrocarbon intersections were as follows:

Maingit Clastics gas zone from 816 – 836 metres. Drill-stem test No. 6 flowed gas to the surface in 3 minutes and recovered 67.5 metres of gas-cut mud and water. Engineering analysis concluded that this zone had the capacity to flow at 5.6 mmscfd.

Toledo Sandstone gas zone from 1,847 – 1,877 metres. Drill-stem tests No. 8 flowed gas to the surface in three minutes and recovered 140 metres of gas and oil-cut mud. Engineering analysis concluded that this zone had the capacity to flow at 12.5 mmscfd.

A 10-metre sandstone section at the top of the Malubog Formation at 2,179 metres produced gas to the surface in 36 minutes and recovered 26 metres of gas and oil-cut mud. The gas flow potential was estimated to be in the order of 1 mmscfd.

Three tests over a 48-metre interval in the sandstone section at the top of the Malubog Formation recovered significant amounts of good quality, clean oil of 39º API in the test pipe. Drill-stem tests No. 13, 14, and 15 recovered 10, 21 and 20 metres of oil respectively in the test pipe.

The presence of liquids in the tests suggests that the gas may contain condensate.
