Harken Energy Subsidiary Mobilizes Rig to Macarenas # 1 Well on
Rio Verde Contract in Colombia 


DALLAS, Dec. 21  /PRNewswire-FirstCall/ -- Harken Energy Corporation (AMEX:HEC)
announced its 85% owned subsidiary, Global Energy Development PLC ("Global"),
has commenced rig mobilization to the Macarenas # 1 well on its 75,000 acre Rio
Verde Exploration and Production Contract in Colombia.

The rig has been mobilized from the Tilodiran # 1 well site, also located on
the Rio Verde Contract.  The Tilodiran # 1 well was successfully re- completed
and placed on production earlier this month.

Terms of the Rio Verde contract require Global to re-complete and equip for
production both Tilodiran # 1 and the Macarenas # 1 wells.  The Macarenas # 1
was drilled in 1993 and, like Tilodiran # 1, tested productive. It was drill
stem tested at a rate of 320 barrels per day of 33 degree API gravity oil.

Global expects that re-completion operations on Macarenas # 1 will require
approximately 35 days, following final mobilization, to equip the well for
production.  Global owns a 100% working interest in the Macarenas # 1 well.

"The progress made to date on our Rio Verde Contract continues to run ahead of
our initial expectations," said Stephen C. Voss, Global's Managing Director. 
"Tilodiran # 1 rapidly supplemented our existing production, and we expect the
Macarenas # 1 should follow shortly.  In addition to further near- term
production the Rio Verde Contract offers potentially significant opportunities
for additional development around the two existing wells which have been our
near-term focus.  Looking ahead, we believe exciting exploration opportunities
exist throughout the remaining acreage."
