GAS DEVELOPMENT INTERESTS – ONSHORE ALBANIA
GAS DEVELOPMENT INTERESTS
In May 2020, the Energy Development Group, has expressed interests in acquiring rights to further develop two existing depleted gas fields in onshore Albania: Povelca and Frakulla fields.
EDG’s technical evaluation underscores the significance of field rejuvenation by a rigorous recompletion and stimulation program which modern technology could be brought to bear.
POVELCA GAS FIELD:
The onshore ‘Povelca Field’ lies in the western part of Albania, along the Adriatic coast and discovered by DPNG (former AlbPetrol) in mid-80’s (Figure 1, a, b). The dry gas has been found in a stratigraphic-structural trap of Upper Miocene (Messinian – Tortonian) formation. The turbidites reservoirs are over-pressured and confined in a south-north trend within a channelized slope system.
The gas field has been under production till 2011, since then, no production has been recorded. Actually, the field is shut down due to lack of consumers and lack of investments. The last two wells that have been into production till 2011 are Pov-13, 23, with average production of 1500 – 2000 m3 per day.
FRAKULLA GAS FIELD
The onshore ‘Frakulla field’ lies in the western part of Albania, just south of Fieri town (Figure 1, a, b). The field has been discovered by DPNG (former AlbPetrol) during 70’s, based on 2D seismic lines and following the south-north geological trend of Trevllazer-Frakulla buried Neogene anticline. The gas has been found mainly in a combined (stratigraphic-structural) trap of Upper Miocene (Messinian – Tortonian) formation. The sandstone reservoirs are developed in a deltaic depositional environment.
The gas reservoirs were discovered above the overpressure zone. Some tentative drilling within the overpressure zone failed to discover commercial gas. The deeper section in Frakulla anticline seems to be of shaly foresets of Upper Miocene.
Actually, the field is shut down since 2011 due to lack of market and investment interest. The last four wells that have been into production are Fr-19, 36b, 106 and 109, with total average production of ~ 4500 m3/d.
A careful analyses and introducing modern logging and w/o jobs, could increase the chances to drain more gas from actual wells and by employing new sidetracks in the existing wells.
