- Salamander [LON:SMDR] was one of sector's top risers after it announced that first oil had been received in the tanks of the newly converted Suksan Salamander floating storage and offtake vessel at the Bualuang field in the Gulf of Thailand.

"This is the culmination of the planned upgrade to the field's facilities which targets a reduction in operating costs of up to $25 million per annum," the company said.

"New power and processing modules were loaded out to the Bravo platform in the first half of the year. These have been operating smoothly since hook up and commissioning in May.

"The FSO arrived on location in July. Following hook up and commissioning the new FSO is now fully operational. As well as halving the day rate of the production vessel, these upgrades double water handling capacity, increase potential production rates and extend the productive life of the field.

"The Rubicon Vantage Floating Production, Storage and Offtake vessel will depart the field in the coming weeks.

Salamander chief executive James Menzies said: "We have upgraded production infrastructure in the Bualuang field on both time and budget.

"The new facilities enhance the value of the field, minimise the risk of future downtime and mean we are well positioned for the next phase in the field's growth."

Cairn Energy [LON:CNE] posts an after-tax loss of $62m for the six months to the end of June - down from $219m a year ago.

Unsuccessful exploration costs of US$80m included US$51m relating to the Foum Draa and Juby Maritime wells offshore Morocco, US$25m relating to North Sea appraisal wells drilled on the Skarfjell discovery and US$4m in other regions.

Cairn said that controlling administrative cost levels was a continuing priority and it is currently re-organising the group to ensure staffing levels are appropriate for the future work programme. As a result, a restructuring provision of US$3m has been made at 30 June relating to proposed redundancies, with associated accelerated share-based payment charges of US$4m. A further restructuring provision will be required in H2 2014. Net operating expenses have therefore increased year-on-year to US$30m (H1 2013: US$25m).

Chief executive Simon Thomson said: "Cairn's future programme of high quality development projects and material exploration drilling is fully funded through to delivery of free cash flow from 2017.

"The company is focused on creating value and shareholder returns from disciplined capital allocation across a balance of exploration and development assets.

"Over the next 12 months, the company has an active programme of exploration and appraisal wells with all drilling beyond the current frontier operations targeting mature and emerging basins. In line with this strategythe farm-in to the Statoil-operated Ensis prospect in the Barents Sea commences a planned entry to this emerging region. In the meantime the Company is addressing its organisational size to ensure it has the appropriate structure to deliver the future work programme.

"Cairn continues to seek resolution of the tax issue in India and will take all necessary steps to protect shareholders' interests."
