Petrominerales Corp., Calgary, said its Taya-1 well on Corcel Block 31 in the Llanos foothills of Colombia production-tested at the rate of 5,218 b/d of 23.2° gravity oil upon recompletion in the Mirador formation.
The majority of the production test was conducted using an electric submersible pump and an open choke with 14% drawdown. The well also produced a 30% water cut. For the last 6.5 hr that the well was producing on ESP, the rate stabilized at 5,169 b/d with a 37% water cut.
The average oil rate through a 192/64-in. choke over the entire production test period was 5,218 b/d with 23 psi wellhead pressure. Total recovery was 11,741 bbl of oil and 5,054 bbl of water, confirming the excellent quality of the Mirador reservoir.
As previously reported, well logs indicated 42 ft of potential net oil pay in Mirador and 31 ft in the Guadalupe formation. Prior to recompletion, the well was producing 315 b/d of oil from Guadalupe. After producing the reserves in the Mirador, the company can isolate the Mirador and produce the remaining reserves in the Guadalupe.
For the rest of 2013, Petrominerales plans to drill at least two more wells in the area. They are Canaguay-2, an appraisal well on the recently acquired Canaguaro block, subject to the ANH approval, and one more exploratory well, Ceibo-1 on the Guatiquia block on trend with Candelilla and Yatay oil pools.
