Beach Energy Provides Monthly Drilling Report For November 2017

Announced Date :  Dec 07, 2017


Beach Energy Limited (Beach Energy) has provided monthly drilling report for the month of November 2017.
HIGHLIGHTS

- Cooper Basin JV horizontal oil drilling campaign commences with early success.

- Western Flank gas exploration success at Naiko-1.

- Total depth reached at Haselgrove-3 ST1 with evaluation to commence soon.

DEVELOPMENT – COOPER AND EROMANGA BASINS

South Australian Oil – Cooper Basin JV

(Fixed Factor Area JV: Beach 20.21%, Santos 66.60% and operator, Origin 13.19%)

A six-well campaign to develop the McKinlay Field, located approximately 50 kilometres southeast of the Moomba processing facility, has commenced. The campaign comprises four horizontal wells and two shallow vertical wells and is designed to develop the McKinlay Member which is a proven producer. The low relief nature of the structure is considered highly suited for horizontal drilling.

Field development with this technique is expected to require fewer wells relative to a pure vertical program, with improved flow rate and ultimate recovery. The first well of the campaign, McKinlay-12, drilled a lateral section of 1,220 metres with good oil and gas shows in the primary target and was cased and suspended as a future producer. The second well of the campaign, McKinlay-15, drilled a lateral section of 870 metres with good oil and gas shows in the primary target and was suspended as a future producer.

A single development well was drilled in the Odonata Field, located on the Nappacoongee-Murteree Horst approximately 50 kilometres south of the Moomba processing facility. Odonata-2 targeted the Coorikiana Sandstone as a primary objective. The well encountered 6.7 metres of net oil pay and was cased and suspended as a future producer

The gas development and appraisal campaign targeting the Patchawarra Formation in the Namur Field continued. The campaign has been modified to consist of three development wells and one appraisal well (previously two). The first three wells of the campaign, two development wells and the appraisal well, are being drilled from a single pad. The first development well, Namur-8, was drilled to develop the central area of the crestal part of the Namur Field. The well intersected 61 metres of net gas pay and was cased and suspended as a future producer. The second development well of the campaign, Namur-9, spudded on 30 November 2017 and at month-end was drilling ahead at 742 metres. The Namur Field is approximately 20 kilometres southeast of the Moomba processing facility.

EXPLORATION AND APPRAISAL – COOPER AND EROMANGA BASINS

Western Flank Gas – ex PEL 106

(Beach 100%)

Beach continued its FY18 operated gas exploration and appraisal campaign, which is focused on the Southwest Patchawarra (SWP) and Permian Edge (PE) play fairways. The fourth exploration well of the campaign, Naiko-1, is located in the SWP play fairway approximately two kilometres northeast of the Middleton gas facility. Naiko-1 was designed to test viability of the gas and condensate system within the SWP play fairway in the mid-to-lower intervals of the Patchawarra Formation. The well intersected two metres of net pay in the mid interval and was cased and suspended as a future producer. An open hole drill stem test was conducted over the interval 2,692 to 2,697 metres and flowed at up to 5.8 MMscfd on a 32/64” choke at 1,149 psi flowing tubing head pressure. Preliminary analysis of test results indicates that Naiko-1 is potentially connected to the Middleton Field and as pressure is higher than at Middleton, will likely add reserves.

The campaign continued with the fifth well, Largs-1, located in the SWP immediately south of the Middleton gas facility. Similar to Naiko-1, the well is testing the viability of the gas and condensate system within the SWP play fairway in the mid-to-lower intervals of the Patchawarra Formation. At month-end Largs-1 had reached total depth of 2,284 metres and evaluation of the well was underway. A vertical seismic profile was conducted, augmenting existing regional seismic data in order to enhance evaluation of future drilling prospects.

The appraisal well of the previously mentioned gas development and appraisal campaign was pad drilled in the Namur Field. Namur-7 intersected net gas pay of 23 metres in the target Patchawarra Formation and was cased and suspended as a future producer.

A two-well gas appraisal campaign also in the Namur Field but targeting the Coorikiana Sandstone was successfully completed using the Ensign 950 shallow rig. The second well of the campaign, Namur-6, encountered 5.3 metres of net gas pay in the target zone and was cased and suspended as a future producer.

(Fixed Factor Area JV: Beach 20.21%, Santos 66.60% and operator, Origin 13.19%)

A two-well near field exploration campaign was successfully completed using the Ensign 950 shallow rig. The campaign was designed to assess near field exploration opportunities that might not have been economic with other drill rigs.

The first well of the campaign, Warumpi-1, targeted a Birkhead Formation prospect located approximately 40 kilometres south of the Moomba processing facility and to the north of the Alwyn Field. The McKinlay Member was a secondary objective. The well intersected seven metres of net oil pay in the primary target and was cased and suspended as a future producer.

The second well of the campaign, Isoptera-1, targeted a Coorikiana Sandstone prospect located between the Bugito and Ulandi fields, approximately 45 kilometres south of the Moomba processing facility. The well intersected net oil pay of 6.5 metres and was cased and suspended as a future producer.

EXPLORATION AND APPRAISAL – OTWAY BASIN

South Australian Gas – PPL 62

(Beach 100%)

Beach completed drilling Haselgrove-3 ST1 in the onshore Otway Basin. The well is targeting conventional gas and gas liquids prospects in the Pretty Hill and Sawpit sandstones. Encouraging gas shows were seen in both target zones and at month-end the well was being prepared for further evaluation.
