1. Lagoven, Caracas (Venezuela)

Four gas fields, Mejillones, Patao, Dragon, and Rio Caribe, were discovered by Lagoven, a subsidiary of Petroleos de Venezuela S.A., during an exploratory campaign during 1978-1982, offshore northeastern Venezuela. Thirteen wells drilled in the four fields discovered 13.9 tcf of gas, including 1.2 tcf of gas and condensate in the Rio Caribe field. In February 1991, Lagoven entered into an agreement with Shell, Exxon, and Mitsubishi to assess the viability of producing and exporting gas from the four offshore gas fields in the form of liquified natural gas. This is the Venezuelan LNG Project, otherwise called the Cristobal Colon Project. As part of the agreement the participants established a Project Team in Caracas and undertook the acquisition of 1600 km[sup 2] of 3D seismic data over the four fields to evaluate the geological model of the area. In addition, interpretation of the 3D data has led to a preliminary geological model for the gas bearing sands which envisages deposition in a regional setting varying from bathyal turbidites in the Rio Caribe and Mejillones fields in the west to shelf deposits over the Patao and Dragon fields in the east. In addition to the geological setting this paper will discuss preliminary results of the reserves evaluation for the Rio Caribe, Patao, and Dragon fields.
