Abstract
An injection spool for use in the injection of a fluid, for example a slurry of drilling cuttings, into a subsea wellhead assembly has an outer housing having a central bore therethrough. The housing has a first end for connection to a wellhead assembly such that the central bore of the housing is aligned with the central bore of the wellhead assembly. An inner housing, for example an isolation sleeve, having a central bore therethrough is disposed within the central bore in the outer housing, whereby a cavity is formed between the inner housing and the outer housing. A port in the outer housing has an opening into the cavity between the inner housing and the outer housing, through which a fluid may be injected. The inner housing has a portion extending from within the outer housing beyond the first end of the outer housing for forming a cavity within a wellhead assembly to which the injection spool is connected. The cavity thus formed connects the cavity in the injection spool with an annular cavity defined by adjacent casings present in the wellhead assembly. In this way, a fluid injected into the injection spool through the port in the housing flows into an annulus between two casings in the well, from which it can be injected into an underground formation.
