Woodside's full year results will be released on Wednesday with Macquarie forecasting a $US2.63 billion ($A3.4 billion) net profit after tax - a 37% year-on-year gain.

In terms of management commentary, Macquarie was seeking timeline confirmation for the Browse floating LNG project.

It said current milestones, which include entering the front-end engineering and design phase in mid-2015 and a final investment decision in mid-2016, could come under further scrutiny and noted that Browse partner Shell was prioritising the LNG Canada venture.

Macquarie also questioned whether Woodside's acquisition appetite was still lingering since its $US3.75 billion deal with Apache which should close in the June quarter.

"With oil markets expected to remain oversupplied throughout 1H15, Woodside may be able to take advantage of the narrowing bid/ask spread between asset buyers and sellers over the next 6 months through further acquisitions," Macquarie said.

Santos' results are due next Friday with Macquarie estimating $A547 million NPAT - a 9% gain from the previous year.

While it is seeking "funding clarity" from Santos management, the broker noted that the Gladstone LNG project was not part of the $A2.4 billion of pre-tax impairments Santos announced yesterday.

In a separate report today, Macquarie said it suspected that Santos would hold out on any GLNG impairments until first LNG production when there was greater certainty around capital expenditure and schedule.

"Our discounted cash flow [estimate] still remains $US1.1 billion below the estimated carrying value of $A6.9 billion," the broker said.

Oil Search's full year results are due out on February 24 with Macquarie forecasting a $US474.8 million ($A613 million) NPAT which is 131% up year-on-year.

Some exploration budget cuts are expected, excluding the potential PNG LNG-expanding Southern Highlands drilling campaign in Papua New Guinea.

The broker flagged that a new dividend policy could emerge due to the PNG LNG profits while it also expects Oil Search management to "reflect" on the PNG Gulf province block PRL15 arbitration ruling which went in French super major Total's favour.

"We suspect focus will quickly shift to ongoing Elk/Antelope appraisal [PRL15] and the merits of Total as operator," Macquarie said.

The broker forecast Beach Energy's full year NPAT to fall 50% to $A78.8 million with the actual results due on February 23.

Macquarie commented that Beach's cash buffer was partially eroded and also viewed that the economics of Cooper Basin shale appeared challenging since the fall in oil prices from last year.
