Preliminary log evaluation indicates that the Heimdal III main sand contains 83ft of net oil pay with an average porosity of 38.8 % and an average oil saturation of 87.2%.
No Oil Water Contact (OWC) was encountered in the Heimdal III main sand and thus the Kraken Field oil-down-to (ODT) has been extended to a depth of 3,934ft TVDss (1,199m TVDss), from the level of 3,842ft TVDss (1,171m TVDss) indicated in the 9/02b-2 well.
Upon completion of wireline logging, a 9.5/8″ casing string was run and a 50ft interval was perforated.
A test string consisting of sand screens and an electric submersible pump (ESP) was run and the well was production tested.
The testing program was specifically designed to recover uncontaminated reservoir fluid samples and to confirm the productivity of the reservoir tested in the discovery well, 9/02-1A.
The well was initially pumped at a restricted rate of 300 barrels per day.
A productivity index of 2bpd/psi was indicated during this flow period, confirming the multi-Darcy quality of the reservoir and subsequent to this flow period, the productivity declined markedly.
An injectivity test was completed which showed an injectivity index of approximately 2bpd/psi, indicating that the productivity decline was due to the plugging of the sand screens, rather than a reservoir or oil quality issue.
The well was thereafter produced at low rate in order to recover oil fluid samples which will be used for development studies.
Nautical has a 35% equity interest in the block.
