Eni’s Mizton-2 well boosts Mexico’s Area 1 resource potential

Eni SPA has increased the estimated resource in place for Mexico’s Contractual Area 1 to 1.4 billion boe after its Mizton-2 well in Campeche Bay encountered 185 m of net oil pay in the Orca formation.

The well, 200 km west of Ciudad del Carmen, was drilled to a final depth of 3,430 m in 33 m of water. The firm reported excellent quality sandstone reservoirs.

Well data indicate a single 280-m thick oil column, and oil gravity is estimated at 28-30°. Mizton-2 is 10 km from the firm’s Amoca discovery reported in June (OGJ Online, June 12, 2017).

Extensive borehole data acquisition along with a fluid and rock sampling campaign were carried out. The well will now be temporarily suspended. Eni’s exploration campaign will continue with the drilling of a well on the Tecoalli discovery.

Eni holds 100% interest in Contractual Area 1. Development of Mizton field, which is now estimated to hold 350 million boe in place, will be included in the Area 1 development plan.

Eni also is preparing a development plan for Phase 1 of Amoca field, which will be submitted to Mexico’s Comision Nacional de Hidrocarburos (CNH). Start-up there is expected in early 2019.

Separately, Eni signed exploration and production licenses for Blocks 7, 10, and 14 in Mexico’s Sureste basin following their award in first-phase Round 2 bidding (OGJ, June 26, 2017, p. 18).

Eni will operate Block 7 with 45% interest alongside partners Cairn Energy PLC with 30% and Citla Energy SAPI de CV 25%; Eni will hold 100% interest in Block 10; and Eni will operate Block 14 with 60% interest alongside partner Citla with 40%.
