Within the Tertiary Clastics Play, Frontera has identified and high-graded the area associated with the existing Mirzaani Field, the Patara Shiraki Field and the Nazerlebi Field. This area is referred to as the the ''Mirzaani Field Exploration Area" and it contains a trend of shallow, Pliocene-age fields that were discovered prior to the grant of the Block 12 PSA.
Within this area, oil has extended into and out of the synclinal axis of the trapping folds. This provides a good indication of the significant quantities of oil generated in the Upper Kura Basin where Block 12 is situated. Oil appears to be migrating into these structures both laterally along carrier beds, and vertically along basement related faults, creating what appears to be a very efficient charge system for the area.
The producing reservoirs discovered prior to the grant of the Block 12 PSA are situated at depths of between 900 metres and 1,300 metres. These shallower fields have historically produced approximately seven million barrels and are today producing at a nominal rate of approximately 100 bpd. However, below the existing fields Frontera has identified a new geologic play, characterised by Miocene-age, Sarmatian reservoirs that are similar to those found in the Taribani Field. These reservoirs are situated at relatively shallow depths of 1,800 metres to 2,500 metres and Frontera believes that this deeper play could open up a new trend of significant potential within Block 12.
2005-2007 Work Program
As shown below, Frontera has mapped an anticlinal structure beneath the existing Mirzaani Field and has developed the Mirzaani Deep Prospect, in addition to other similar prospects throughout this area. Over the next three years, Frontera plans to drill new exploratory wells into the Mirzaani Deep Prospect in order to test this new deep play, as well as access secondary targets in the shallow play potential that exists throughout the area. In preparation for drilling operations, Frontera will acquire new seismic data over the area in 2005. If drilling operations are ultimately successful, Frontera intends to drill appraisal wells in order to delineate fully the structure and establish plans for development and associated infrastructure upgrades. As the location for the Mirzaani Deep Prospect sits beneath the existing shallow production at the Mirzaani Field, tie-in to existing production facilities will contribute to efficiency in development.
