The Design and Execution of Frac Jobs in the Ultra Deepwater Lower Tertiary Wilcox Formation

Abstract: A considerable amount of effort goes into designing one of the deepest frac jobs in the world. For the past several years, Petrobras has been working on developing the Cascade and Chinook fields which are located in the Gulf of Mexico (GOM), 250 miles south of New Orleans in ultra deepwater depths between 8200 ft and 8900 ft. The oil producing reservoir is in the Lower Tertiary Wilcox formation with a gross sand thickness of 1200 ft. The reservoir mid-point is at an average depth of 25, 600’ TVD with a bottomh… Show more

“…7 The initial plans called for four fracture treatments using a total proppant volume of 800,000 lb of bauxite. Additional details of the C&C fracturing design program are discussed in great detail by Haddad et al (2011Haddad et al ( , 2012. Thus the perforation intervals were properly positioned to take advantage of the expected height growth from the fracs.…”

“…A 10 -1/8Љ x 10 -3/4Љ production casing was run through the pay interval and cemented in place. Haddad et al, (2011) presented Frac-Pack designs for Single-Trip Multi-Zone sand control system. The completion objective was to install the MST assembly and Frac-Pack two zones in Wilcox 1 sand, then run selective isolation equipment and the 4 -1/2Љ production string.…”
