Iecea Mica-1 Well – Results Update
ADX Energy Ltd (ASX Code: ADX), is pleased to report the following additional
analysis of results from the Iecea Mica-1 (IMIC-1) well located in the Iecea Mare
production license onshore Western Romania.
Further to the ASX release dated 26 August 2019, ADX can report that the
preliminary petrophysical analysis of wireline log data from the 8 1/2” hole
intersection has further confirmed ADX’s interpretation of the presence of a
number of potential hydrocarbon pay zones already indicated from mudlog
data observed while drilling. These pay zones represent confirmation of
previously identified appraisal potential (Contingent Resources) such as the
Pannonian (PA) IV sand as well as zones previously assessed as exploration in
nature (Prospective Resources).
A summary of the interpreted pay zones is listed below:
1. PA III Interval (pre drill assessment was exploration potential) - In line with
the previously reported gas peaks at 1863 meters MD (drilling depth) within
the PA III stratigraphic interval two separated sandstone reservoir zones at
1851 and 1861 meters MD (logging depth), respectively have been identified
on logs. The pay thickness for each sand is in the order of 2 to 2.5 meters with
porosities in the order of 25% and interpreted permeabilities in excess of 100
MD. The pay thicknesses and porosities have the potential to add to the
potential gas resources from this well.
2. PA IV Interval (predrill assessment was appraisal potential based on historic
well results) - As expected the previously successfully tested PA IV sandstone
at a depth of 2030 meters MD (logging depth) has resulted in pay containing
dry methane (C1) in a gross reservoir interval of 8 meters based on logs. The
porosities are in the order of 20% with interpreted permeabilities up to 100
mD. The interpreted porosity and permeabilities analysed on modern logs are
at the upper range of expectation.
3. PA V Interval (pre drill assessment was exploration potential) - The stratified
sandstone and siltstone section from 2140 to 2165 meters MD (25 meters
gross thickness, logging depth) has shown a number of potential reservoirs
in the PA V stratigraphic interval with heavier gas condensate shows (C1, C2
& C3) and fluorescence observed while drilling. Encountering potential pay
at this interval is encouraging because the log signature encountered in the
IMIC-1 well is very similar to a downdip (60 meters approx.) well which is 2.5
kilometres to the north and has produced at an oil at a rate on test of 126
bbls oil/day. The conventional quick look petrophysical analysis only shows a
total of approximately 4 meters of pay zones with porosities of 15% or less.
The zone is interpreted as multiple thin pay zones containing very finely
laminated sandstone intervals which cannot be resolved with the standard
