July 14 (Reuters) - Australia's Woodside Petroleum Ltd WPL.AX on Tuesday forecast a first-half loss of $4.37 billion after tax, as it joined oil majors BP BP.L and Shell RDSa.L in writing down several assets after a coronavirus-induced slump in oil prices.
The company said it expects to book non-cash, post-tax impairment losses of $3.92 billion related to the write down, and a further $447 million charge related to an onerous liquefied natural gas sale and purchase agreement.
