Ecopetrol finished drilling the Gibraltar 3 well, located in the Siriri block in the Northeastern Region of Colombia.
The Gibraltar well was drilled to delimit the Gibraltar gas field as well as to prove the existence of structures and reservoirs in the deeper zones of this field.
The initial tests proved that Gibraltar 3 is a gas and condensate producing well within the upper thrust sheet of the Mirador formation (Gibraltar field), thus ratifying the results obtained from the drilling that took place at the Gibraltar 1 and 2 wells. In the tests conducted, the Gibraltar 3 well had natural gas production in the range of 28 and 30 million cubic feet of gas per day (mcfd), with a one inch well choke opening, and 54 degrees API hydrocarbon production of 530 barrels per day (bpd).
However, in terms of the second target, the well did not have a presence within the Mirador and Barco deep thrust sheet formations, which are located at a depth between 12 thousand and 16 thousand feet.
The results of Gibraltar 3 well, combined with those of the Gibraltar 1 and 2 wells, guarantee the supply of the gas volumes the Company had previously (30 mcfd) and give way to the possibility of commercializing additional gas production in the future.
In order to commence gas production at the Gibraltar field, Ecopetrol entered into an agreement with the firm Union Temporal Gas Gibraltar to carry out the design, construction, operation and maintenance of a treatment plant, with a 30 mcfd capacity, which is estimated to start operations later this year. Similarly, an agreement was entered into with Gas Natural E.S.P. for the commercialization of this gas production. Consequently, Gas Natural E.S.P. has entered into an agreement with TransOriente E.S.P. for the construction of the gas pipeline that will transport gas from the Gibraltar field to Bucaramanga Refinery, where it will connect with our national gas transport system.
