Nido Commences Sidetrack Program at Tindalo Well

Nido, as Operator of Service Contract 54A (SC 54A), updated on the Tindalo-1 well intervention and remediation program.

Tindalo-1 has been re-entered and the completion removed. The original program next called for retrieval of the downhole perforation equipment to allow access to the wellbore for diagnostic logging which was proving to be a time-consuming exercise. Since the logging was a non-critical element of the remediation program, the potential information gain was closely weighed against the cost to continue leading to a decision to cancel the logging program and proceed directly with the sidetracking the well.

The sidetrack program has now commenced following the successful cementing of the existing wellbore and will effectively provide a new well drainage location in the crestal part of the field. Details of the forward program are summarized below:

  • Drilling of Tindalo-1ST1 will commence September 13;
  • Tindalo-1ST1 will be drilled at a high angle to vertical and will intersect approximately 150m of reservoir section within the top 50m oil column;
  • Once drilled, Tindalo-1ST1 will be competed barefoot with pre-drilled, slotted liner;
  • The sidetrack activities are expected to be completed by the second half of September, following which the Extended Well Test will continue; and
  • The offtake window for the first cargo has been planned to coincide with well activities and is scheduled for 16-18 September, subject to weather.

Nido's Deputy Managing Director, Ms. Joanne Williams, said, "The operational risk, cost and schedule impact of undertaking this sidetrack program has been greatly reduced by having the jack up rig Aquamarine Driller on site and with access to the well. This flexibility was a critical risk management strategy employed during concept selection and final design of the Tindalo development."

Nido will provide a further update on the progress the in-field operations once the well remediation work has been completed and the Extended Well Test has recommenced.
