Mitigate shale formations, in which loss of returns and sticking are common, by combining SET® expandable tubulars with sidetracking operations in order to reach additional reserves with optimized hole size.
Isolate the trouble zone while conserving hole size by planning solid expandable technology into the well design; optimize wellbore trajectory and reduce risk in sidetrack drilling operations.
Install a SET® Openhole solid expandable system fitted with injection-moulded composite standoff blades.
The customer was sidetracking the well, and unable to run their 16-inch liner. The 13-5/8 inch and 11-3/4 inch casing were both set high, which would compromise the originally planned 8-1/2 inch hole size.
The operator selected a 9-5/8 x 11-3/4 in. SET®...
A major operator was sidetracking out of an existing well to a nearby reservoir.The first attempt to sidetrack utilizing a conventional casing design failed to reach the target depth and damaged the 13-3/8 in. casing.
The casing design for a...
Challenge: Redevelop an established Gulf of Mexico deepwater field by accessing additional reserves.
Isolate a low fracture-gradient zone to enable an optimal completion.
Install a Solid Expandable Tubular (SET®) system to isolate the trouble zones. Retain hole size across all the depleted sands in a narrow pore pressure/fracture gradient environment....
The SET liner permanetly isolated the loss zone allowing the well to maximize reservoir contact.
