Suggested placement of ROTCO's solid slip-on centralizers with the ROTCO centralized up-jet float shoe and ROTCO centralized float collar (optional):
Placement of the ROTCO Intercasing Centralizer on Integral Flush Casing For close tolerance wellbore/casing annulus productive zones:
Note: Pipe reciprocation or rotation with any fixed centralizer will deteriorate stand-off because of the centralizer's wear and/or formation.
Objective: To achieve good cemented shoe joints and good upper cement coverage for load support. Approved centralizers for sub-sea wellhead wells.
Solid Centralizer Placement (1 per joint):
Objective: To achieve good cemented shoe joints and shoe tests. To get isolated zones of good cement. Sub-sea wellhead approval.
Solid Centralizer Placement:
Objective: To achieve good cemented around the shoe joints. To achieve isolated zones of good cement. Solid Centralizer Placement
Objective: The objective is to achieve casing stand-off throughout the productive intervals. Stand-Off will allow complete mud removal and complete cement coverage. Solid casing centralizers can be perforated with no deformation or degradation of the shot.
Solid Centralizer Placement
Objective: To achieve good cement coverage around the casing shoe joints and liner overlap.
INTERCASING CENTRALIZERS FOR CLOSE TOLERANCE WELLBORES
Objective: To achieve casing stand-off through the productive intervals and liner overlap for complete cement coverage.
