2.2 DRILLING OBJECTIVES

The primary target in Connolly-1 is the Jurassic-aged Hutton Sandstone and the underlying Basal Jurassic sands.

OILEX00 2

ATP 545P was granted to Roma Petroleum in 1994, and predates Native Title. The Connolly prospect was worked up from seismic shot in 1995. It is a large drape of the Eromanga Basin sequence over basement, located 130 km south of Longreach in western Queensland.

The Connolly location was selected to test the crest of a seismically defined structure with four way dip closure, overlying an erosional cuesta of the Devonian unconformity surface. The cuesta is flanked by dipping half grabens of Devonian marine section.

Mesozoic Eromanga Basin sandstone reservoirs directly overlie an angular unconformity which exposes a large section of the lower Adavale Basin sequence. Drape and compaction over this erosional high has maintained the Connolly feature as a palaeo-high throughout deposition of the sedimentary section in the area. This cuesta was unaffected by structuring associated with the widespread Tertiary compression in the area. This type of play, located in an area of many minor oil shows, until now has never been tested in the area.

Most of the oil reservoired in the Eromanga Basin is in sandstones of the Hutton Formation, sealed by shales of the Birkhead Formation. Together with sands of the Basal Jurassic, Adori and Namur Sandstones, these exhibit porosity of an average of 20%, often with permeabilities of at least 1 Darcy. Other reservoirs are not as good but are still capable of good production rates. The expected hydrocarbon was light oil.

Regional Geology

Geologically, ATP 545P overlies five distinct sedimentary sequences. The lowermost section consists of sediments of the Devonian-Carboniferous Warrabin Trough of the Adavale Basin. It is unconformably overlain by the Permo-Triassic Northern Cooper Basin which is in turn unconformably overlain by the Jurassic-Cretaceous Southern Eromanga Basin.

The Eromanga Basin sequence begins with the Basal Jurassic unit, equivalent to the Poolawanna Formation, of fluvial sandstones, siltstones, shales and coals. The widespread Hutton Sandstone was deposited as an extensive braided stream system in the late-Early Jurassic. Overlying the Hutton are the floodplain and lacustrine sediments of the Birkhead Formation. These two units compose the second cycle of the Eromanga Basin sequence.

The third cycle begins with the coarse-grained fluvial sandstones of the Adori Sandstone which is conformably overlain by floodplain siltstones and shales of the Westbourne Formation.

The fourth and final cycle consists of the Early Cretaceous Hooray Sandstone, overlain by the Cadna-Owie Formation, a coarsening upwards, fine-grained, calcareous sandstone of a fluvio-deltaic to lower shoreface origin. A widespread transgression followed, with the deposition of the shallow marine shales of the Wallumbilla Formation. This unit is then overlain by the shallow marine and fossiliferous Toolebuc Formation. Depositional energy continued to wane and the Allaru Mudstone was deposited. A regression occurred, which resulted in the deposition of the sandy siltstones of the Mackunda Formation. Terrestrial sedimentation resumed with the fluvial, lacustrine and coal swamp sediments of the Winton Formation. Rapid sedimentation occurred until the early

3.1 OPERATIONS SUMMARY

3.1.1 Rig

Rig150, a Soilmec G-102, Hydraulic Trailer Mounted rig was contracted from Mitchell Drilling Contractors Pty Ltd for the purpose of drilling the Connolly-1 well

3.1.2 17 ½” Hole Section

The well was spudded at 0400 hours on 8 August 2004 when a 17 ½” hole was drilled to 17m and 13 3/8” conductor string was set at 17m at 1200hours on 9 August 2004.

3.1.3 12 1/4” Hole Section

A 12 ¼” bottom hole assembly (PDC Bit) was made up and run in hole. Hole was drilled from 17mKB to 191mKB by 0100 hours on 10 August 2004. POOH and 15 joints of 36lb/ft 9 5/8” casing run to 183.45 mKB, this was cemented with 315 sacks of “A” cement at equivalent mud weight of 15.6 ppg and displaced with 39 barrels of fresh water and

OILEX00 2

bumped, cementing was completed at 1600 hours on 10 August 2004. BOP’s were installed and nippled up and tested by 0600 hours on 11 August 2004.

3.1.4 8 ½” Hole Section

The 8 ½” BHA with a PDC bit was run in the hole and tagged cement at 168m, the cement and shoe were drilled out and a FIT run with a result of 11.6 ppg EMW. The 8 ½” hole was drilled ahead with surveys at 2130 hours on 11 August 2004. The section was drilled to 1103m at 1600 hours on 13 August 2004 where a wiper trip was made back to the surface casing, 1 m of fill was tagged on return to bottom. The well drilled ahead at 0130 hours on 14 August 2004 to a depth of 1388m at 1600 hours on 15 August 2004. The hole was cleaned in preparation for a bit change, hydraulic power was lost whilst POOH causing a delay of 4.5 hours. The BHA was at surface at 0630 hours on 16 August 2004, the bit was changed for another PDC and the BHA was RIH reaching bottom at 1430 hours on 17 August 2004 encountering 1 m fill. The well drilled ahead to 1724 mKB by 0200 hours on 20 August 2004 when the string was pulled due to a suspected twist-off when a loss of 16,000 lb weight and 150 psi pump pressure occurred. The string was at surface by 0930 on 21 August 2004 confirming loss of BHA comprising Bit, Bit Sub, 2 x 6” drill collars, stabiliser, 7 x 6” drill collars, cross over and 1 x 4 ¾” drill collar. Fishing BHA ran in hole at 1530 hours on 21 August 2004 and recovered fish to surface by 0630 hours on 22 August 2004. The drilling of 8 ½” hole recommenced at 1530 hours on 22 August 2004 and reached TD of 1762 mKB at 0645 on 23 August 2004. The hole was circulated and conditioned an the BHA POOH for running of electric logs. One run of wireline logs was conducted between 1500 and 2200 hours on 23 August 2004. At 2300 hours it was decided to abandon the well and set plugs. The rig was released at 2400 on 24 August 2004.

all personnel were present. Regular BOP evacuation drills were conducted whilst drilling the 8 ½” hole section. Safety meetings were held prior to running casing and wireline logs (nuclear source, explosives), appropriate signage was displayed and radio silence was enforced during explosive sidewall core gun run. Camp food preparation areas were maintained hygienically and smoke free. Camp and Rig rooms were regularly cleaned and maintained.

4.0 FORMATION SAMPLING AND EVALUATION

4.1 MUD LOGGING

A continuous 24 hour mud logging service was supplied by Pectil Engineering. Mud logging commenced at 350mKB in the Winton Formation and continued to TD at 1762 mKB. The following services were provided:

(a) gas detection: total gas; chromatographic gas analysis (C1-C5)

(b) monitoring of drilling parameters: lag time measured depth bit location rate of penetration rpm weight on bit hook load bit hours mud pump stroke rate mud pit volumes

(c) formation sampling and analysis: routine description and compilation of samples routine fluorescence detection in cuttings and mud

A mud log (Formation Evaluation Log) at 1:500 scale was maintained during the drilling. The Formation Evaluation Log is attached as Enclosure 2.

4.2 DITCH CUTTINGS, CONVENTIONAL CORES AND SIDEWALL CORES

7.0 SUMMARY

The Connolly-1 well was designed to test the hydrocarbon potential of the Connolly Prospect. Drilling objectives were achieved to required TD, drilling took approximately two days longer than prognosed due to repairs required to rig and a twist-off of the BHA. Formations penetrated occurred close to prognosis and facies were as expected. Producible oil potential was not confirmed though there is evidence from fluorescence that the structure may have at one time held hydrocarbons or was part of a migration pathway. The structure was plugged and abandoned, the data collected will be used to further enhance potential within the remainder of the block.

1. SUMMARY OF OPERATIONS

Connolly-1 was spudded on the 8th August 2004 using Mitchell Drilling Rig-150 and reached a depth of 1,655 m on the 19th August 2004, at which point the mud engineer was released.

Initially a hole was Air Hammer drilled and a 13-3/8" Conductor set at 17 m.

HOLE SIZE : 12¼"MUD TYPE : Gel Spud Mud INTERVAL : 0 - 191 m

CASING : 9 5/8" @ 183.45 m

There was no Mud Engineer on location during this interval, which was drilled with Gel Spud Mud to 191 m. The casing was run and cemented at 183.45 m without any problems.

HOLE SIZE : 8½"MUD TYPE : KCl PHPA Polymer INTERVAL : 191 m - 1,655 m (TD)

There was no Mud Engineer on location during most of this interval and the well was at 1,388 m when the Mud Engineer arrived on location. A few mud checks were made by the Mud Logger, and the Company Man called RMN Drilling Fluids for advice on what treatments should be made until the Mud Engineer arrived.

The shaker was dressed with the only screens available of a more or less suitable size, a 60 mesh over a 80 mesh. No other sizes were available on the rig, other than coarser screens and one used 100 mesh.

After the BOPs had been nippled up and pressure tested, an 8½" bit was made up and run in the hole. Cement was tagged at 168 m. The casing was pressure tested to 1500 psi. The cement and shoe were drilled and a Formation Integrity Test (FIT) was run for an equivalent mud weight of 11.6 ppg.

After the FIT the mud in the hole was displaced with KCl PHPA mud while drilling continued. The mud was cement contaminated. After displacement the screens were overloaded with cuttings and a lot of mud was lost over the end of the shakers to the sump, and this was recycled back into the mud pits with a sump pump. Due to the shortage of mud pit space fresh water was added directly to the active system and KCl was mixed at the hopper simultaneously. As drilling continued the PHPA and polymer content of the mud was brought up to spec by mixing directly into the active system.

OILEX00

It was not possible to make premixes because the rig did not have a slug pit or other mixing pit. The mud pits consist of 3 small pits in one tank, with only one agitator. The maximum working surface volume is only 160 - 180 bbls.

The Desilter was run constantly and appeared to work well. The sand trap was dumped periodically to remove settled sand and solids. The mud weight stayed in the range of 8.9 - 9.6 ppg.

The rheology was maintained with PAC-R or XCD Polymer added directly to the active system when needed.

Soda Ash was added to reduce the hardness, Sodium Sulphite was added as a corrosion control agent, and Biocide was added because the fluid was being recycled from the sump.

At 1,388 m a bit trip was made but the rig hydraulics broke down with the bit at 363 m while pulling out. There was some tight hole on this trip (Max 10K overpull) but never again after this. A survey showed the hole angle was only 1/2 a degree. The hole was circulated slowly while rig repairs were carried out over about 2 days.

As drilling continued deeper it was necessary to add more fresh water because recycling the sump water was causing the mud weight to increase too much. The mud was also lightly treated with XCD Polymer to increase the yield point. The bottom shaker screen (B80) was replaced with a used B100 screen (the only B100 screen on location) to improve solids control.

Drilling continued slowly. AMC Pac-R and PHPA additions were maintained to control the fluid loss at around 6 cc's, with the PHPA also aiding in controlling solids. However, dumping and dilution with sump water was still required to control the weight under 9.5 ppg. Also, soon after the B100 screen was fitted it failed and so had to be replaced by a B80 screen.

Drilling continued through to 1655 m where the mud engineer was released as the ROP was slow and TD had almost been reached. It was anticipated that when TD was reached, that the hole would be logged and then Plugged and Abandoned.

2. OBSERVATIONS, RECOMMENDATIONS AND WELL ANALYSIS

Connolly # 1 was drilled to 1655 m for a mud cost of $20,058.10 or $12.12 per metre. The well was drilled problem free from a mud viewpoint and hole conditions were good throughout. The make up water was of good quality.

The rig had small pits and no slug pit or other pit suitable for mixing pre-mixes, so all chemical additions had to be made directly into the active system. From a mud point of view the most serious problem was the inability of the shale shaker to handle the volume of mud required for drilling. The main problems were that shaker was just too small, and the bed angle could not be adjusted upwards to hold back heavy flow rates. The rigs desilter generally worked well.

12¼" Surface Hole

There was no mud engineer supervision for this section.

8½" Production Hole

This section was drilled for a mud cost of $19,844.15 or $13.55 per metre. There was no mud engineer present for the drilling of the top section of hole through to 1350 m.

A simple KCl - PHPA system was used to drill the top section and as the Cadna- Owie approached, AMC Pac-R was added to increase the viscosity and lower the fluid loss.

When the fluid loss had come down to spec, XCD Polymer was used to maintain the yield point and AMC Pac-R was used only to maintain fluid loss control. The mud weight was maintained below 9.5 ppg as required.

The desilter was run as much as possible while recycling the sump water and adding fresh water to maintain volume and control solids.

The higher pressure water aquifer seen on an offset well did not appear and no weighting up of the fluid was required.

Overall, a change to the mud program is not required, simply because the system worked very well and achieved its aims of helping drill the hole cheaply, quickly, efficiently, and without undue hole problems. KCl PHPA based systems are ideal for the Eromanga Basin and are by far the most cost effective, normally delivering good calliper logs, stable hole conditions and minimal hole related down time.

Dumping and diluting with recycled sump water and fresh water to keep solids and mud weight under control. Water additions has reduced pH so started adding Soda Ash to reduce hardness. Increased dilution requires

increased use of Pac R to keep Fluid Loss down. Added Sodium Sulphite for corrosion control.
