Abstract
Temporary abandonment caps include a cap body having an opening therethrough, and an inner sleeve that provides access to the wellbore, where the inner sleeve can be accessed through the opening in the cap body when a removable cover is removed. The inner sleeve also includes an injection port and a channel through which fluids for protecting the wellhead can be injected. The temporary abandonment caps can remain in place while performing well operations and ensuring that the sealing surfaces on a wellhead remain protected from corrosion.
