Talisman Energy Inc. affiliate Talisman (Colombia) Oil & Gas Ltd., and Ecopetrol S.A. have proven the presence of hydrocarbons in the Nueva Esperanza-1 exploratory well (A2b), located in block CPO-9, Department of Meta, Colombia.
The Nueva Esperanza-1 well was spudded on July 18, 2014 and reached total depth at 12,056 feet on September 26, 2014. During an initial 8-day flow test using an electro submersible pumping system, 309 feet of perforations in the T2 formation stabilized at a daily flow rate of 910 barrels of 8° API crude oil with less than 2% water cut during the last day of flow.
Talisman and Ecopetrol are jointly analyzing the results and will file an application with the Colombian authorities to place the Nueva Esperanza-1 well on long-term test. Approval has been granted to drill two down-dip appraisal wells, the first of which, Nueva Esperanza-2, started drilling operations on November 16.
