Yesterday the well was at a depth of 119m, the same depth it was at the previous Thursday.
"During the week, a series of loss zones were encountered in the near surface section and several attempts were made to cure these losses," Oil Search said.
"Preparations are now underway to mobilise equipment to site to allow deepening of the 30-inch casing to resolve the issue."
The drilling in petroleum retention licence 11 is managed by Oil Search on behalf of well operator ExxonMobil.
Trapia 1 (formerly Huria) is 13km east of the Angore gas field and 23km east of the key PNG LNG project field of Hides.
The Toro and Dimu sandstones are the key targets but seismic has identified similar leads to Trapia in petroleum prospecting licence 277 next door.
Oil Search owns 52.5% of PRL11 while Exxon PNG subsidiary Esso Highlands owns 47.5%.
