Lakach, Mexico's first subsea gas development with onshore processing facilities, is located 93km southeast of Veracruz, Mexico, 131km northwest of Coatzacoalcos in 850-1200m water depth. It is targeted to supply 400 MMscf/d.
Aker will supply approximately 73km of electro-hydraulic steel tube umbilicals that will help connect Lakach to its onshore facilities.
The umbilicals will be manufactured in Mobile, Alabama, and the order will be completed in 3Q 2016.
In October 2014, Saipem took home a $750 million contract covering the engineering, procurement, construction and installation of the system connecting the offshore field with the onshore gas conditioning plant, in addition to developing the subsea, umbilicals, risers and flowlines (SURF) facilities, which include subsea equipment, infield umbilicals, flexibles and trees and control system installation.
That same month, OneSubsea was awarded a deal from operator Pemex worth US$270 million to provide subsea production equipment and tooling for the seven-well system in addition to installation and commissioning services. Deliveries are expected to begin in June 2016.
The Lakach field
Pemex first discovered two deepwater gas finds in 2005, Noxal and Lakach.
Noxal-1, the deepest water well the country had ever drilled at the time, was spudded in December 2005 and required an estimated US$50 million investment.
The well is located 102km northwest of Coatzacoalcos off the coast of Veracruz, situated in 935m of water in the Catemaco Folded Belt.
Noxal-1 was drilled by Diamond Offshore’s Ocean Worker semisubmersible and targeted both the Middle Miocene and Lower Miocene formations.
Testing at four intervals on Noxal-1 proved the well was gas-filled, with an initial production rate of 10 MMcf/d and estimated reserves reaching 6.9 Bcm of natural gas. The 3P reserves at Noxal-1 are estimated at 16.5 Bcm of natural gas, 11.9 Bcm of dry gas and 80.8 MMboe. The success at Noxal-1 led Pemex to confirm that the Coatzacoalcos Profundo area contained 10 boe.
Pemex began drilling the Lakach-1 well shortly after Noxal-1.
The well, located 131km northwest of Coatzacoalcos, Veracruz and at 988m water depth, it is the deepest well to date that Pemex has drilled.
Lakach-1 discovered non-associated gas in the Lower Miocene formation. The fourth-largest gas field discovered in Mexico, Lakach-1 is estimated to contain 1.3 Tcf of 3P gas reserves.
