Santos’ six-well campaign to develop the McKinlay oil field, 50 km southeast of the Moomba facility in South Australia, has been successfully completed.

The campaign comprised four horizontal wells and two vertical wells, and was designed to develop the McKinlay Member reservoir, which is a proven producer.

The third and fourth wells, McKinlay-13 and McKinlay-14, drilled lateral sections of 1,397 m and 811 m respectively with each encountering good oil and gas shows in the primary target.

Both wells were cased and suspended as future producers.

The two vertical wells of the campaign, McKinlay-16 and McKinaly-17, were successfully completed by the Ensign 950 shallow rig, intersecting 4.4 and 6.3 m of net oil pay respectively, with both cased and suspended as future producers.

The six development wells are expected to be brought into production by the end of FY18.

Furthermore, the gas development and appraisal campaign targeting the Patchawarra Formation in the Namur Field, 20 km southeast of Moomba, has been completed.

The campaign consisted of three development wells and one appraisal well, with the first two development wells and the appraisal well drilled from a single pad.

The final pad well of the campaign, Namur-9, intersected 53 m of net gas pay and was cased and suspended as a future producer.

The rig was subsequently moved to drill Namur-10, which intersected 61.5 m of net gas pay and was also cased and suspended.

These drilling campaigns were undertaken by the Cooper Basin Joint Venture, made up of: Santos (66.6 per cent and operator), Beach Energy (20.21 per cent) and Origin Energy (13.19 per cent).

The ATP 299P Tintaburra Joint Venture also commenced a four-well oil appraisal campaign using the Ensign 950 shallow rig, targeting the Kooroopa, Mulbery and Takyah fields in southwest Queensland.

The first well of the campaign, Mulberry-37, targeted the Birkhead Formation and intersected 3.7 m of net oil pay and was cased and suspended.

The second well of the campaign, Takyah-3, targeted the Birkhead Formation as a primary objective and the Murta Formation as a secondary objective.

The well intersected 4.1 m of net oil pay in the Murta Formation and has been cased and suspended as a future producer.

The ATP 299P Tintaburra Joint Venture is made up of Santos (60 per cent and operator) and Beach Energy (40 per cent).
