Abstract

Abstract:

The exploration potential of the Llanos Basin in Colombia was made clear by the method of play analysis. The
geological evaluation of the basin was made firstly，secondly the play evaluation，then the petroleum geology features and
the resource potential of each 2nd order play，and the exploration direction was pointed out lastly. The basin has excellent
accumulation conditions and perfect accumulation model. According to the oil and gas bearing situation of each reservoir，
the basin was divided into 3 sets of 1st order play，including the confirmed central play，the potential upper and lower plays.
According to the six principles of the structure of the basin，generation-reservoir-seal，oil and gas enrichment characteristics
and so on，the central play was further divided into 4 sets of 2nd order play：the upper Cretaceous，Paleocene，Eocene and
Oligocene. The recoverable resources of all the plays are 3.06×108 tons of oil equivalent，and the upper Cretaceous play is of
the largest resources volume. Upper Cretaceous and Eocene plays are the key exploration plays，and inner slope and foredeep
are the key zones. The steps and rules of play analysis applied in this paper for the first time can be a reference to the study of
plays in other basins.

Key words: play, petroleum geology, exploration potential, Llanos Basin, Colombia
