Ithaca announced that the 42/21b-5z well (the 'Carna Well') has encountered a gas bearing reservoir and is currently being completed for testing, and the 'Energy Enhancer' rig has been contracted to begin completion of the Jacky production well on schedule and as planned.
The Carna Well is currently being cased for further evaluation and drill stem testing. Electric logs indicate the well intersected gas bearing Namurian Millstone Grit Formation (Carboniferous) at 10029 feet TVDSS and indications of formation gas are seen from mudlogs down to 11440ft TVDSS. The well reached TD at 11519ft TVDSS.
Net pay over this interval is estimated from preliminary log interpretation to be 127 feet on a true vertical basis within a 1490 foot gross section of Millstone Grit Formation.
Porosities in the four distinct gas bearing sections of the reservoir range from 14% to 7%. A 294 foot core was recovered and early analysis of the core indicates that permeability ranges from 10mD to 0.1mD. The well results to date indicate that the reservoir and its properties bear similarities to the producing Kilmar field which lies approximately 10km to the northwest of Carna.
Testing will commence in approximately 7 days time. It is anticipated that the well test will take a further 6 days after which the well will be suspended pending further analysis of the results.
The Carna Well was spudded on December 26, 2008 utilizing the rig, Ensco 92, and was mechanically sidetracked at 2,918 ft TVDSS on January 23, 2009.
The co-venturers involved in the Carna prospect are Venture (56%, operator), Ithaca Energy (UK) Limited (29.9%), Dyas UK Limited (10.1%) and EWE Aktiengesellschaft (4%).
Jacky Field Development
The Ensco 92 rig was contracted to conduct the Jacky completion work, but due to the Ensco 92 rig working on the Carna Well and the planned test, agreement has been reached with Ensco to defer the commitment to the Ensco 92 for up to one year and Ithaca has contracted with Northern Offshore for the immediate mobilization of the Energy Enhancer jack-up rig to conduct the Jacky completion. The Jacky field production facilities have been installed, pipelines have been laid and modifications to the Ithaca operated Beatrice reception facilities 10km to the southwest of the Jacky field are nearing completion. Ithaca currently anticipates that Jacky production will commence at the end of March at rates of approximately 7,500 bopd.
The co-venturers in Jacky are Ithaca (67.275%, Operator), Dyas UK Ltd (22.725%) and North Sea Energy (UK) Ltd (10%).
John Woods, Chief Development Officer of Ithaca said, "This is good news for Ithaca. Subject to a successful test on Carna, we will have added another asset to our portfolio in which we hold a material stake. By securing the Energy Enhancer we will be able to deliver first Jacky production in line with our forecasts to the market. It is a testament to Ithaca's Operatorship skills and strong partner support that we have been able to manage the logistics between these two positive events."
