Operations have been completed on the Eni operated Ehecatl-1 exploration well on Block 7, located in the Sureste Basin Offshore Mexico, in which Cairn has a 30% working interest through wholly owned subsidiary Capricorn Energy Mexico.

The exploration target of the well was to prove hydrocarbons in the Lower Miocene.  The well did not find reservoired hydrocarbons and it has now been permanently plugged and abandoned.

Logging, sampling and data collection during the well operations will help the joint venture calibrate the seismic data and develop an improved understanding of the Lower Miocene target and the information gathered will be integrated to improve the understanding of the Block and inform the second well decision.

The well is located 65 kilometres offshore and was drilled by the Valaris 8505 semi-submersible rig in water depth of 426 metres and reached a total depth of 4,451 metres.
