An apparatus and method for stimulating a well, comprising production tubing (20, figure 1B) in the well, the tubing having a side pocket 29, a first wet connector 30 located in the side pocket. There is an insulated electrical conductor connecting the first connector to surface equipment (4, figure 1A) via a wellhead (3, figure 1A). There is an electrically powered tool, which may be an electric submersible pump (ESP), which has a second wet connector which is arranged to engage the first connector after the tool is lowered down the tubing. A protection sleeve (50, figure 2A) is deployed down the tubing where it is sealingly engaged to cover the side pocket to prevent damage to components therein during treatment or stimulation of the well, for example using acid. The protection sleeve may have a recovery profile (55, figure 2B) and resilient fingers (57, figure 2B). |
