Westside Corporation - insights from the new player

New player to the New Zealand energy scene, Queensland’s WestSide Corporation, is taking the lessons learned from its Aussie operations and applying them to operating the Rimu, Kauri and Manutahi oil and gas fields in South Taranaki.

Operations Support Manager Josh Whitcombe told the 2017 New Zealand Petroleum Conference held in New Plymouth during March that the private company, “with its highly experienced team in the Brisbane head office”, was proving profitable by “leveraging its subsurface and production experiences”.

He said the company was employing state-of-the-art techniques involving daily data capture from unconventional coal seam gas (CSG) resources that featured, among other things, low pressures and multiple coal seam gas (CSG) intervals. This data included daily production, sales figures and well-by-well performance statistics.

The company was also investigating “continual improvements” -- production enhancements through “gas lift” and “artificial lift” optimisation techniques, as well as real time data capture and modelling.

Well workovers were also important, with multiple operations done each year.

WestSide has gas production and sales, significant reserves and exploration interests in Queensland. It operates (with a 51 percent stake) the Meridian gas fields, 160km west of Gladstone in Queensland's Bowen Basin, in a joint venture with Mitsui E&P Australia (49 percent), as well as other exploration acreage.

And the Meridian joint venture has gas sales agreement with the GLNG project at Gladstone for the sale of up to 65 Terajoules per day of natural gas, which underpins staged field expansions to increase production. Meridian is also connected to the domestic market through its existing connection to the Queensland Gas Pipeline (QGP) and to the liquefied natural gas (LNG) export market via a more recent connection direct to the GLNG pipeline in Gladstone.

WestSide also holds its own exploration acreage a majority interest with Mitsui E&P Australia in other projects with exploration and appraisal programmes in the Bowen Basin.

“And we are looking to do similar things to realise the potential of our New Zealand assets, ” he said referring to the Rimu, Kauri and Manutahi fields (plus Rimu production station) purchased for an unspecified price late last year from Aussie listed company Origin Energy. These fields produce mainly gas and associated condensate (light oil), with some crude oil, “and Westside sees significant potential in the area”.

 “This year we will concentrate on the reinstatement of previously shut-in wells (at Rimu, Kauri and Manutahi) and we are confident we can achieve similar improvements to those achieved (at the Meridian fields),” Whitcombe concluded.
