Workovers are a normal part of any oil and gas company’s business. Like your car, our oil wells need “tuning up” occasionally to maintain optimum production. Tamarind has a regular schedule of workovers, as well as those “surprise workovers” when something breaks downhole. Most of our wells pump the oil from the ground with the help of a pumpjack – the nodding donkeys!
These types of pumps have up to two kilometres of steel rods connecting the donkey to the downhole pump. Those rods wear out going up and down all day, so replacing those rods is one of the common workovers Tamarind schedules. Tamarind is currently pulling and running rods and pumps into two wells on Cheal B site.
There is also further activity planned in early 2021 for maintenance interventions on Cheal B and Cheal E. Rig availability is currently hindered due to restrictions around rig-crew entry into New Zealand due to Covid-19. However, the team are committed to keeping the project moving and will continue to work towards completing the activity when possible. We will keep you updated as things progress!
