The development stages:Exploration drilling/2011-01.Operated by Niko Resources, the Guayaguayare field covers an area of 113,311ha with onshore and offshore portions at the Columbus basin. It surrounds the Beach Marcelle Field. Four prospective onshore fields have been detected and there is a high offshore gas potential. In 2013, Range Resources and Niko Resources signed an agreement where Range agreed to drill two testing wells in retribution; the first one by early 2014. Range will also fund the two onshore wells and the potential initial appraisal well at its sole expense, and will split costs 50/50 with Niko in the offshore well. Niko currently holds shallow and deep Production sharing contracts for 65% of the onshore portion and 80% of the offshore portion of the license area with the Guayaguayare Block comprising 280,170 shallow acres and 293,999 deep acres. Trinidad's state owned petroleum company, Petrotrin, holds the remaining balance of the interests (35% onshore and 20% offshore).
