InterOil gauges gas at Elk-2 appraisal well

By OGJ editors
HOUSTON, Aug. 17 -- InterOil Corp., Toronto, said it has achieved positive results from its Elk-2 appraisal well on PPL 238 in Papua New Guinea.

"We are now confident that the Elk structure contains sufficient gas to underpin the first train of an LNG plant, which will be built by Liquid Niugini Gas Ltd. adjacent to our refinery [planned at Port Moresby], and sufficient oil shows to justify sidetracking to confirm an oil leg," said InterOil Chairman and Chief Executive Phil Mulacek.

The Elk-2 well was programmed to test the entire 2,000 ft Puri and Mendi limestone section in a downdip position of the discovery well 2.9 miles away (OGJ Online, Feb. 13, 2007).

Drilling and testing at Elk-2 confirmed 4,452 ft of indicated hydrocarbon column from the highest known gas in Elk-1 to the lowest indicated hydrocarbons in Elk-2, InterOil said.

Mud logs indicated multiple gas zones, and there were multiple oil shows throughout a 594 ft column. In addition, the well had flowed gas and gas liquids during a drillstem test, the company said.

The target Puri and Mendi limestone reservoirs are much thicker than predrill estimates, it added.

The company intends to drill the Elk-2 well to total depth, log it, complete it, and test it.

"We will then sidetrack the well to intersect the potential oil leg structurally higher in the porous Mendi limestone section," Mulacek said.

LNG plant progress
InterOil has been designated as the preferred natural gas supplier for the planned Port Moresby LNG project, which consists of a two-train, 9 million tonne/year liquefaction plant having a nominal processing capacity of 1.6 bcfd of condensate and gas liquids, handling and storage facilities, and a gas pipeline from supply sources.

InterOil's Elk and Antelope structures are the key gas resources for the project (OGJ, Nov. 20, 2006, Newsletter).

The company executed a shareholder agreement in July with Merrill Lynch Commodities and Pacific LNG to develop the LNG project. The partners agreed to establish PNG LNG as the holding company for Liquid Niugini Gas, which will own and operate the LNG facility.

The joint venture will proceed with contractor selection and front-end engineering and design work during this year.

LNG production is still on track to begin in 2012, InterOil said.

Global LNG: Adjusting to New Realities

Fri, Mar 20, 2015

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.

The Future of US Refining

Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
