In February 2006, the new Mauritanian government denounced amendments to an oil contract made by former Leader Ould Taya with
Woodside Petroleum, an
Australian company. In 2004, Woodside had agreed to invest US$600 million in developing Mauritania's
Chinguetti offshore oil project. The controversial amendments, which Mauritanian authorities declared had been signed "outside the legal framework of normal practice, to the great detriment of our country", could cost Mauritania up to $200 million a year, according to
BBC News. Signed by Woodside two weeks after the February 1, 2005, legislation authorizing the four amendments, they provided for a lower state quota in the
profit-oil, and reduced taxes by 15 percent in certain zones. They also eased
environmental constraints and extended the length and scope of the exploitation and exploration
monopoly, among other measures. The disputed amendments were signed by former Oil Minister
Zeidane Ould Hmeida in February 2004 and March 2005. Hmeida was arrested in January 2006 on charges of "serious crimes against the country's essential economic interests". Nouakchott's authorities declared that the government would likely seek international arbitration, which Woodside (which operated for Hardman,
BG Group,
Premier Oil,
ROC Oil,
Fusion,
Petronas,
Dana Petroleum,
Energy Africa and the
Hydrocarbons Mauritanian Society) also contemplated. Discovered in 2001, Chinguetti has proven reserves of about of oil. At the end of December 2005, authorities estimated that in 2006, the oil profits would be 47 billion
ouguiyas (about US$180 million) and represent a quarter of the
state budget, according to
RFI. Some U.S. oil companies are alleged to be playing a part in Mauritania's oil related corruption. ==Macro-economic trends==
