Rockhopper logs Sea Lion oil discovery offshore Falklands

Rockhopper Exploration has completed wireline fluid and pressure testing on the 14/10-2 well on the Sea Lion prospect offshore the Falkland Islands. Multiple pressure readings and multiple fluid samples have been successfully obtained.

The Ocean Guardian semisubmersible drilling rig is not equipped with facilities to analyze the Sea Lion fluid samples, so analysis of the fluid samples will take place after the sample containers are shipped to a dedicated laboratory. However, the fluid sampling process suggested that all samples indicated to be oil; the sample chambers filled rapidly, indicating a good quality reservoir with no evidence of any free water as the sample chambers filled; and filling characteristics suggest a mobile crude oil.

Pressure data was good with most attempted test points successfully located in good quality reservoir. Pressure readings indicate the possibility of two separate oil columns; and no oil water contacts or water sands have been recognized in the well.

Wireline sidewall cores have also been collected and the samples will be evaluated for reservoir characteristics in a laboratory.

Rockhopper intends to run a liner and apply to suspend the well for future testing. It is anticipated that operations will take a further week to ten days.

"All current indications are that the oil recovered from the Sea Lion well is moveable which, if confirmed, would be further positive news,” said Samuel Moody, managing director of Rockhopper. “We will now wait for confirmation of the quality of the fluid as a result of the laboratory analysis, and continue our review of the data gathered from the well."
