Oil & Gas Discoveries in Mexico 2015-2019
28 April 2020

From 2015 to 2019, 41 hydrocarbons’ discoveries were reported from the drilling of 112 exploratory wells1, representing one discovery for every three wells drilled.


Exploratory wells2 are direct methods used in exploration activities to identify, discover and appraise hydrocarbons in the subsurface.


Discoveries2 are accumulations of hydrocarbons in the subsurface that, via drilling activities, have been shown to contain hydrocarbons’ volumes.


During this period, a total of 112 exploratory wells were drilled in Mexico; 101 in Entitlement areas and 11 in contractual areas. 28 of these wells were onshore, 55 shallow water, and 29 deepwater wells.


There have been 41 discoveries3 reported in Mexico since 2015; 37 in Entitlement areas and 4 in contractual areas; of which 10 correspond to discoveries made in onshore areas, 26 in shallow waters and 5 in deepwater.


1 Exploratory wells completed during 2015 to the present with reported drilling results are considered, in addition to Saasken. Delimiting appraisal wells are not taken into account.
