Sept 28 (Reuters) - ViaLogy Plc (VIY.L), a provider of sensor technology to oil explorers, posted a wider full-year loss but said it finalized agreements for three onshore oil prospects and that it was confident of steady progress in the coming months.

The company's shares, which have risen 26 percent in the last three months, were up 6.25 percent at 6.375 pence at 0739 GMT on the London Stock Exchange.

ViaLogy, whose patented QuantumRD technology helps firms in locating oil and gas deposits, said to date, it signed contract agreements with six exploration and production companies in the United States and several other potential customers were in the pipeline.

Pretax loss widened to 6.2 million pounds for the year ended March 31 from 5.3 million pounds in the year-ago period.

Revenue jumped more than four-fold to 129,028 pounds.

Loss widened due to non-cash items of 3.8 million pounds consisting of share-based payments and depreciation and amortisation.

In a separate statement, ViaLogy said it finalized project and royalty agreements for three onshore oil prospects with The Buckingham Group of San Angelo, Texas. The contract covers the use of QuantumRD. (Reporting by Purwa Naveen Raman in Bangalore; Editing by Deepak Kannan)
