The fields form a single development block also known as Area 4 located in the Southwest Marine Region off the coast of Tabasco. The fields were formerly part of Pemex's Litoral de Tabasco business unit. Ichalkil-Pokoch was awarded to a consortium formed by Fieldwood Energy and Petrobal. The fields were awarded in September 2015 as part of the shallow-water development opportunities tender in Round One.
