Marram Appraisal Well Proves Gas in East Irish Sea

Venture Production confirmed that the Marram appraisal well, which was spudded on July 1, 2009 using the Ensco 92 jackup rig, has proven gas in the eastern part of the field.

The well reached a total measured depth of 2,020ft on July 9, 2009 and encountered a gross gas column of 469ft within the Ormskirk Sandstone. Down hole samples were taken to confirm the gas quality and the initial analysis indicates that the gas quality is within the pre-drill expectation range. A preliminary assessment of the well results indicates that the gas in place ('GIIP') volume is also within the pre-drill range of expected outcomes. The nitrogen content in the down hole samples is material but other fields in the same area have been successfully developed despite having high nitrogen content and processing facilities already exist in the local infrastructure. A final evaluation will be completed over the next few weeks and potential development options are being reviewed.

The Marram well was designed to appraise the eastern section of the Marram gas discovery made in 1993. Venture holds a 70% interest in the field which is located in blocks 110/4 and 110/9b in the Morecambe Bay area of the East Irish Sea. The discovery lies on trend with both the producing Hamilton and Lennox fields, and is close to the Morecambe field complex. The blocks in which Venture has an interest also have exploration prospectivity and contain up to six additional Sherwood sandstone exploration leads. The well was operated by Senergy on Venture's behalf.


Venture Production's Chief Executive, Mike Wagstaff, said, "Confirmation of gas in the eastern section of the Marram field and the potential for a commercial development is a positive result and one that validates our 2008 entry acquisition to the east Irish Sea. We now look forward to our nearby Whitbeck exploration well, the next activity in the Ensco 92 rig campaign."
