Melbana's gravity and magnetic study supports large prospect identified in Cuba

Melbana Energy Limited has provided the following update on Cuba Block 9 (Melbana 100% and operator).

Recently completed gravity and magnetic study commissioned by Melbana and undertaken by Cuba’s specialist technical laboratory CEINPET over the 71 million bbl Zapato prospect has indicated a strong gravity and magnetic alignment with the structural interpretation Melbana’s technical team derived from seismic and surface data. This result is supportive of Melbana’s assessment of the prospectivity of Zapato as a large carbonate duplex structure along strike from the Motembo discovery which produced light 56°API oil.

Block 9 has high quality detailed pre-existing gravity and magnetic data sets. In the type of geology present in Cuba it is common to use a combination of seismic, magnetic and gravity data sets to define prospectivity. The study of these data sets, when used together, are tools that can be used in the technical de-risking of other large leads and prospects identified in the seismic based interpretation in the southern part of Block 9. Carbonate duplex structures such as Zapato are being targeted by Melbana due to their potential to contain Varadero style oil accumulations and are able to be identified using this technique by their combined gravity and magnetic response which differentiates them from low prospectivity intervals. Melbana is considering use of this technique to highgrade other Block 9 prospects, such as Piedra.

Melbana Energy’s CEO, Robert Zammit, said: “The work commissioned by Melbana as part of its Block 9 work programme supports our structural interpretation and demonstrates the significant potential of the Zapato prospect for high quality light oil similar to that found at Motembo. We are progressing environmental approvals and permitting to allow us to drill Zapato. Several of our potential farmin partners have expressed strong interest in Zapato and we remain flexible in our forward plans.”
