Latest updates on the drilling for CO2CRC’s biggest project to date

Tuesday 1 October 2019

We’ve reached another milestone with the final perforating run successfully completed in the monitoring well, CRC-6. This means we’ve now perforated all five stage 3 wells and avoided any damage to our primary seismic detection cable.  This gives us the best possible opportunity to monitor the entire reservoir area using both DAS and pressure tomography techniques.  No wonder the project manager looks happy!

With our final monitoring well successfully drilled and cased yesterday we now have four new wells at our Otway facility. During the 59 day operation we drilled almost 7km of hole, ran 11km of steel casing, 13km of fibre optics and pumped 2,387 bbl (or 458 tonnes) of cement!


Wednesday 18 September 2019

We completed the drilling of our fourth and final monitoring well over the weekend. We’ve just finished running the casing, complete with fibre optic cables. The end of the drilling program is in sight!

Since we commenced drilling operations in July we’ve hosted the Victorian Government’s Earth Resources department, CarbonNet, Moyne Shire, Geological Survey Victoria, Southern Rural Water as well as local landholders at our Otway facility. We’ve enjoyed showing them around and talking about our project to reduce the cost and environmental footprint of long-term CO2 storage monitoring.

Our third well, CRC-7 has been completed. Casing with fibre optics attached has been installed. We tested they worked by pouring hot water on the fibre optics and checking the increased temperature was picked up, as shown on the laptop screen image below.

On Sunday we completed the drilling of CRC-7 to a measured depth of 1703m. This is our third well completed out of four. Today we ran the 5 ½” production casing and fibre optic cables.

It was great to have Southern Rural Water visit the site. They enjoyed seeing the drilling first-hand and learning how the project will provide alternatives to conventional CO2 monitoring techniques that are low cost, low impact, fast and on-demand.

This is how our Otway facility looked at 6.27am this morning. The drilling is a 24-hour operation. One 15 person crew works 12 noon – 12 midnight. Another crew takes over for the 12 midnight – 12 noon shift. The crew sleep in on site cabins. There are also cooks and cleaners on site.


Monday 26 August 2019

The drilling of our deepest well, CRC-5, is complete.  It was cased down to 1,810 metres with fibre optics installed on the outside.  The rig has now been moved and the drilling of the next well has commenced.  It’s currently at a depth of 300 metres.


Monday 19 August 2019

It was a busy weekend at the Otway facility. Wireline logging operations started late Saturday night on CRC-5 and continued through to Sunday morning. This allowed us to identify the target injection zone and confirm the geological prognosis.


Tuesday 13 August 2019

We’ve started drilling CRC-5. The top hole section is complete and has been cased and cemented. We’re now at 1,002m measured depth.


Thursday 8 August 2019

Today we were pleased to show regulators from Earth Resources around the Otway facility, and talk to them about our work to reduce the cost and environmental impact of monitoring CO2 stored underground.


Tuesday 6 August 2019

We have now completed the first well!  Cementing then installing and pressure testing the wellhead on CRC-4 took place yesterday.

“Despite some wet and windy weather, we have completed the first well and achieved all safety and technical objectives. With the rig and crew now well adjusted to the conditions and the well characteristics, we’re now turning our attention to drilling the next well, CRC-5. It’s great to have this first well under our belt, to have identified and addressed the teething problems, taking the lessons learned across to the next one,” said Paul Barraclough, CO2CRC’s stage 3 project manager.


Monday 5 August 2019

A critical milestone was reached early this morning when two casings with fibre optic lines attached were installed. The primary fibre optic cable extends from surface to 1729m MD (measured depth). Both cables have been tested and are working.

The wireline logging run was completed today on the open hole production section prior to running casing.

This was performed in two runs.  The first to establish the well geology and to facilitate our initial selection of the target zone.  The second was a more in depth measurement of the physical and geophysical properties of the Paaratte aquifer and above-lying formations.​

We are half way there with the drilling of CRC-4.  Once completed the well will be  1,764m deep.  The more complex directional drilling, at an angle of 21.9 degrees, has now started.


Thursday 25 July 2019

It may be a little wet at the Otway National Research Facility today but the drilling goes on regardless! We have now drilled the top hole section of CRC-4, down to a measured depth of 950m.

Monday 22 July 2019

The Stage 3 drilling campaign has started at CO2CRC’s Otway National Research Facility, located at Nirranda South, Victoria.

Around midnight drilling started on the first of four new 1600-metre-deep monitoring wells.

This work is part of CO2CRC’s Otway Stage 3 Project which will develop technologies which reduce the cost and environmental footprint of long-term COstorage monitoring for carbon capture and storage (CCS) projects.

Drilling operations will continue for ten weeks until the end of September.
