Due to a technical problem we had to pull the cement string out of hole this morning. While the string was out of hole the opportunity was used to pump a tracer substance into the well. This test is a continuation of tests that have been ongoing in the Krafla area this summer. An international team will be monitoring the production wells over the next weeks and months to look for the return of the injected tracer. The crew was ready to run in with the string again this afternoon. We now expect to cement the casing around midnight, tonight.
