Melbana Energy (ASX:MAY) has experienced a delay in its appraisal well drilling program, due to the Cuban government requesting its drilling contractor to drill a second gas well to increase the electricity output of a power plant.

The company says the delay is only temporary and would result in a possible saving to the appraisal program in excess of $1M.

Melbana Energy's Executive Chairman, Andrew Purcell, believes that this delay has potential financial advantages and they will communicate progress as they draw near to mobilisation.
