ResumoThe Poza Rica field is the most important producing structure in Mexico. On the surface this structure is reflected in upper Oligocene clays, sands, and lenticular limestone of the Coatzintla formation. This structural nose dips east-southeast and becomes more accentuated in the subsurface down the stratigraphic column until the Tamabra limestone is reached. This limestone is Albian-Cenomanian in age and production comes from a porous facies that crowns the axial zone. It is proposed that the structure was a tectonic high during Tamabra time, whence the origin of the reef facies. The reduced section of Mendez shales and San Felipe limestone formations above the Tamabra is suggested as diagnostic of the presence of reef facies for future Tamabra tests in the Tampico Embayment. This structure is producing approximately 100,000 barrels per day and has an accumulated production of approximately 8,943,167,855 cubic meters of gas and 50,754,198 cubic meters of oil to August, 1948. Some considerations are made regarding future developments and commercial disposal of the gas produced.
