DALLAS, Nov. 6 /PRNewswire-FirstCall/ -- Continental Energy Corporation
(OTC Bulletin Board: CPPXF) today updated progress of the drilling activity
currently being conducted by its 18% owned Indonesian subsidiary
Continental-GeoPetro (Bengara-II) Ltd. in the Bengara-II block East
Kalimantan, Indonesia.
The Seberaba-1 was originally planned to reach a total depth of 4,000m.
Drilling of the Seberaba-1 terminated at a depth of 2,914m in the third of
three sidetracks made from the original wellbore. Each of the 3 sidetracks
was made necessary by stuck drill pipe resulting in 3 sections of drill
string or "fish" being lost in the original hole and the first two
sidetracks. A 7" liner was set at TD of 2,914m in the third sidetrack and a
drill stem testing program commenced.
Testing activity of the Seberaba-1 has been suspended. Approximately
150 barrels of crude oil has been recovered by swabbing. Flow test and
pressure build up tests to date have proved inconclusive due to apparent
formation damage. Analysis of core samples has indicated that a certain
type of naturally occurring clay mineral in the reservoir intervals is
sensitive to both pH and salinity changes in the fluids used during
drilling. These clays expand when subjected to filtrate from fresh water
based drilling fluids and occlude or choke off permeability in the
reservoir near the wellbore hampering flow.
The Seberaba-1 wellbore has been suspended and preserved for possible
re-entry and deviation away from the damaged reservoir interval. In such
case the well would be re-drilled with a different drilling mud and testing
fluid program to avoid damage to the target reservoir intervals. A decision
to deviate and re-drill Seberaba-1 will be made at some time next year once
other drilling results on nearby wells are complete.
Drilling activity on the Seberaba-3 well continues below a 9-5/8"
casing shoe set at 1,101m. Currently an attempt is being made to sidetrack
the Seberaba-3 after stuck drill pipe resulted in an 800m long fish being
lost in the original hole before logs could be obtained. A cement plug has
been set on top of the fish and preparations are being made to sidetrack
the well and re-drill the lost hole from a depth of 1,600m. The Seberaba-3
is planned to a total depth of 2,800m to test possible reservoir zones
below 2,400m.
Drilling activity on the Seberaba-4 has been terminated after logs were
run and a 7" liner set at 2,572m. Seberaba-4 failed to encounter an
expected reservoir sand expected at 2,450m probably because the wellbore
penetrated a normal fault and the expected reservoir interval was faulted
out. The Seberaba-4 wellbore has been suspended and preserved for possible
re-entry and deviation away from the fault at some time next year once
other drilling results on nearby wells are complete.
Drilling of the Punga-1 well continues below 1,700m to a planned total
depth of 2,800 meters. No objective formations have been encountered yet.
