Buru Energy to plug and abandon Victory 1 well

As previously reported, logs over the lost circulation zones showed potential cavernous or vugular porosity below a drill depth of 1,945 metres. Due to the log quality, deep fresh water invasion and hole conditions, it was not possible to determine from logs whether or not hydrocarbons are present in this zone. Logs were initially unable to be obtained deeper than approximately 2,030 metres due to hole conditions and several further attempts have been made to log the lower part of the hole below the lost circulation zone with no success. The difficulties in acquiring the logs were principally due to a well developed shale section below the zone of lost circulation.

During these operations, further problems with the casing were encountered. After considering the options for remedying the issue, and the associated costs, it is has been agreed that the most prudent course of action is to plug and abandon the well bore, meaning that a flow test of the horizon where circulation was lost, though warranted, was not operationally achievable. Abandonment will be done in accordance with all regulations and good oil field practice to ensure all formations are effectively isolated.
