Initial log while drilling data indicates at least 63ft (19mt) of reservoir, which is lower than assumed in pre-drill estimates at this location. Net pay over the section drilled remains to be determined and Valiant is currently running a data collection program having cored the reservoir and running suite of wireline logs, fluid sampling, pressure readings and a vertical seismic profile.
Once all of the data has been analyzed and the reservoir is better understood, the net pay has the potential to increase in this part of the field.
The company will now undertake to drill its planned sidetrack targeting the four-way dip ‘T1’ structure (the West Tybalt prospect) immediately to the west of the current well. Based on the offset well data in the area, the reservoir properties are expected to improve in this well location.
Valiant is also reviewing a number of additional appraisal options around East and West Tybalt, including an additional sidetrack and a drill stem test, in order to fully understand the regional reservoir properties to potentially facilitate the near term development of the area.
Peter Buchanan, CEO of Valiant, said: “We are pleased with the early indications from the East Tybalt well. In the event of further success in the West Tybalt side-track well, Valiant believe that sufficient hydrocarbon volumes will have been identified to proceed with a development either on its own or alongside the development/re-development of the other fields in the area including the nearby Valiant-operated Banquo and Helena discoveries.”
Valiant acts as operator of the blocks with 80% stake with the remaining stake is held by Agora Oil & Gas (UK).
