ExxonMobil plans to spud the Mesurado-1 well on Block LB-13 in late 2016 or early 2017, according to the 2016 work programme sent to block partner Canadian Overseas Petroleum (COP). The well, to be drilled in the second exploration phase of the contract, aims to prove a commercial quantity of hydrocarbons in the Cretaceous Santonian age reservoirs, and to provide calibration for the seismic response, which can be used to evaluate other leads on the block.
