Just spotted this (02-11-06) from Petrolatina (formerly Taghmen) a British based oil extraction outift that has been looking to exploit oil reserves in Guatemala:

"Petrolatina shares lost 2-1/4 pence at 16-1/2 after the firm said it is suspending well 1XD in its Guatemala operations as it is not producing at commercial levels because of an 'apparent lack of energy in the reservoir'.

The company is carrying out more detailed geological studies on the Las Casas structure within the 6-93 licence. Its service rig will now move to the A7-2005 licence to carry out a work over of Atzam 2, which was originally drilled in 1993." Source: lse.co.uk
