Ku-Maloob-Zaap is located offshore in the Bay of Campeche, off the coast of Tabasco, 105 kilometres (65 mi) from Ciudad del Carmen.
It covers an area of 121 square kilometres (47 sq mi), and includes five fields: Ku, Maloob, Zaap, Bacab, Lum, and Zazil-Ha.
The Ku, Maloob, and Zaap fields produce from the Kimmeridgian, Lower Paleocene-Upper Cretaceous, and Middle Eocene reservoirs.
KMZ is among the company’s most profitable producing assets, according to Welligence Energy Analytics.
On 2 July 2021, Mexico's state-owned oil company PEMEX suffered an undersea gas pipeline rupture in the Ku-Maloob-Zaap field.
