The Miahuapan block features 100% of 3D seismic information with the Miquetla, Miahuapan, Cohuca and Furbero prospects. 14
History of Exploration and Development The discovery of the fields belongs to the Miahuapan block, in the year of 1948, upon drilling of the well Miahuapan-5, in 1957 the well Zapotalillo-2 was drilled, with commercial oil production at an initial rate of 1,849 bpd, with 0% water and 186 m 3 /m 3 of GOR from Tamaulipas Inferior-Pimienta formation; then in August 1961, well Zapotalillo-3 was completed with a rate of 157 bpd, 0% water and GOR 88 m 3 /m 3 from Tamabra formation. The maximum production rate reached was 1,080 bpd oil in June, 1976 from Tamabra formation; now (30-06-2012) production is 348 bpd oil. The saturation pressure is 156 Kg/cm 2 (data from PVT of Esfena-1 well, close to the area) and the reservoir pressure is between 78 and 150 Kg/cm 2 (2,200 mv). In 2010, operation and maintenance operations were resumed, reactivating wells with minor repairs in the Coyotes and Horcones fields, which are on the East of this Block; it is worth mentioning that the average rates prior to reactivation (April 2010) of wells was 20 bpd, of 79 wells in operation, with a monthly average of 1750 bpd and currently (July 2012) the average rate is 30 bpd with 110 wells in operation and an average monthly production of 3300 bpd. Drilling activities resumed in 2011 and 2012; three horizontal wells were drilled, and to this day, two have been completed: Coyotes 423D and Coyotes 276D, both completed with multifraccing (five) and the initial rate for the former was 400 bpd net oil @ 37 °API and 0.471 mmmpcd with 30% water cut, which dropped to 15%; the initial rate for the latter was 318 bpd of oil @ 28° API and 0.093 mmmpcd of gas and and 35% water cut; it is still undergoing cleaning operations, hence the water cut is expected to drop as in the first well. 15
