PORT MORESBY, Jan 17 (Reuters) - From her red-roofed home near Papua New Guinea's capital of Port Moresby, Isabelle Dikana Iveiri overlooks a giant plant used by Exxon Mobil Corp to liquefy billions of dollars' worth of natural gas before it is shipped to Asian buyers.
Dikana Iveiri can also see swaths of muddy shoreline, where mangroves have been felled for firewood by locals who don't have electricity, gas, or money to buy either.
The $19 billion Exxon-led PNG LNG project was supposed to be a game-changer for PNG, a vast South Pacific archipelago beset by poverty despite its wealth of natural resources.
But much of the promised riches, through taxes to the government, royalties to landowners and development levies to communities, have arrived well below Exxon's own commissioned forecasts, if at all, according to landowners, the World Bank and the PNG government.
"My family has been here a long time," said Dikana Iveiri, one of several landowners interviewed by Reuters near the PNG LNG plant. "Our royalties are not going well; they are using our land but not paying us properly," she said referring to both Exxon, which pays the royalties and the government, which distributes them.
Since gas exports began more than four years ago, Dikana Iveiri said she had received just one royalty payment in 2017. She was expecting about 10,000 kina ($2,885) based on information given to her by the government and community leaders. She said she received 600 kina.
Exxon, community leaders and the government did not comment on Dikana Iveiri's specific situation but in a statement to Reuters, Exxon said distribution of royalties and benefits to the LNG plant site landowners started in 2017. Cash payments to individual landowners would depend on how many landowners were in a precinct and were just one of the benefits communities received, Exxon said.
The project employs nearly 2,600 workers, 82 percent of whom are Papua New Guinean and Exxon said it has invested $360 million to build infrastructure and pay for training and social programmes.
"We could not be more pleased to see how the benefits are flowing to the communities at the LNG plant site, to see how investments are being made in important infrastructure such as schools and health that demonstrates the process is a good one and it works," ExxonMobil PNG Managing Director Andrew Barry told a mining and energy conference in Sydney in December.
Barry said Exxon was hoping royalties would begin flowing in the pipeline and upstream areas "in the not too distant future".
The government admits it has made mistakes.
PNG Prime Minister Peter O'Neill, who was part of the government but not the leader in 2009, said many of the disputes around PNG LNG stemmed from the way the government and Exxon proceeded with the project without first resolving landowner claims.
"It should have been done before, it wasn't only for Exxon and the partners but even the government at the time did not do the proper clan vetting, proper identification of the land owners - they allowed this project to go on without that," O'Neill told Reuters.
Treasury, the treasurer, and the Prime Minister's spokesman declined to provide responses to Reuters' questions about the project.
GAS-POWERED MONEY SPINNER
PNG LNG was completed ahead of schedule and exported 8.3 million metric tonnes in 2017, compared to its anticipated design capacity of 6.9 million tonnes, according to the project's website.
Exxon does not disclose the project's revenue or profits but research house Morningstar estimates it has generated $18.8 billion in revenue for Exxon and its partners since production started in 2014.
The project's break-even price of around $7.40 per million British Thermal Units (mBTU) compares favourably to an average over $10/mBTU for eight recent gas projects in the region, according to analysis by consultancy Wood Mackenzie and Credit Suisse.
"The plant capacity has performed phenomenally," Credit Suisse analyst Saul Kavonic told Reuters. "On cost, it's much lower than peers ... it's got an ample resource base and it's got a well-disciplined operator in the form of Exxon."
The project's contribution to Papua New Guinea's economy and government finances is less clear.
PNG's Treasury does not report project income figures, but government budget papers show tax revenue flowing from PNG LNG has been well below expectations.
In its 2012 budget, the PNG government estimated it would receive $22 billion in revenue over the project's life to 2040.
In November, the government slashed its revenue forecast in half to $11 billion over the life of the project.
It identified 11 tax concessions, which along with a drop in gas prices, amounted to hundreds of millions in kina in annual revenue forgone.
A 2017 World Bank analysis found the project partners had negotiated favourable methods of calculating royalties to the government that allowed them to take various deductions.
Combined with tax concessions, the project created "a complex web of exemptions and allowances that effectively mean that little revenue is received by government and landowners," the World Bank said.
Exxon did not respond to questions regarding the World Bank findings and the World Bank declined to provide further comment.
Exxon's partners, which include Australian-listed Oil Search Ltd and Santos Ltd, and a subsidiary of Japan's JXTG Holdings Inc, referred Reuters' questions to Exxon.
Exxon said in a statement to Reuters the project has generated 5 billion kina in revenue for the government and landowners via taxes, royalty and benefit payments. The figure includes revenue to the PNG state-owned stakeholders.
A second LNG project, Papua LNG, led by France's Total with Exxon and Oil Search as minority partners, is scheduled to finalise an agreement with the PNG government in early 2019.
Papua LNG, a new gasfield using the same but expanded processing plant, could commence production as soon as 2024, according to Total. Analysts estimate it will cost around $13 billion.
"The experience of the first project developed by Exxon and Oil Search, there was some criticism, some mistakes," Total CEO Patrick Pouyanne told Reuters in an interview in Port Moresby, referring to relations with landowners.
"Some lessons (are) being taken out … around the management of landowners and trying to engage at an early stage with them."
Total has agreed to an undisclosed annual minimum payment to the government and to reserve some gas for local industry, he said.
Exxon did not respond to requests for comment on Pouyanne's statements.
In its statement, Exxon acknowledged that "distribution of royalties and benefits in some project areas were delayed since the start of production due to court action by a small number of landowners which prevented the relevant government departments from completing their administrative processes."
Exxon said it was committed to assisting the government ensure landowners receive royalty and equity dividends as soon as practicable.
Disputes have broken out within communities near PNG LNG facilities as landowners fight to have their claims recognised.
Some clashes have been fatal, said Highlands clan leader Johnson Tape, one of 16 clan leaders with a claim over the Komo Air Field, used by the Exxon project.
"Our clans fought each other, but now there is peace; we are one team fighting Exxon," said Tape.
Christopher Havieta, the governor of Gulf Province, where gas fields for the new project are located, said locals wanted to avoid the experiences of Exxon's PNG LNG.
"It was a foundation project and so a lot of exemptions were made and the end result is we have a lot of social problems that have risen up." ($1 = 3.4662 kinas)
