Dorado 2 Core Workshop – Register Now!

MGPalaeo are running a one-day integrated workshop focussing solely on the Dorado 2 core, drilled in the Bedout Sub-basin in 2019, and registrations are now open!

Dorado 2 was the first appraisal well of the Dorado oil and gas field which was discovered in 2018. Dorado 1 discovered hydrocarbon bearing reservoirs in the Caley, Baxter, Crespin, and Milne members of the Lower Keraudren Formation. Dorado 2 was drilled down-dip approximately two kilometres from the Dorado 1 discovery and encountered 85m of net reservoir in the primary Caley Formation, and 32m of net pay in the underlying Baxter and Milne sandstones.

The 233m of Dorado 2 core will provide detailed palaeoenvironmental insights into the Middle Triassic Caley and Baxter reservoirs, through the integration of sedimentology, ichnology, and palynology.

Details are as follows:

Date: 28 July, 2021 [dependent upon release of the core]

Venue: DMIRS core facility, Perth, WA

Registration: email [email protected]

This workshop is not to be missed!

Also, keep an eye out for our Perth Basin integrated core workshop, slated for late September. More information on that will be coming soon.

From the Pinnacles to post-glacial Permian Plays of the Perth Basin

Here’s something a little different this time, as we wanted to give a summary of the recent Perth Basin fieldtrip that Amely helped run, plus discuss our upcoming Perth Basin core workshop. As such, the following is by Chris Watts:

We’ve sadly packed away our hiking boots following a three-day geological fieldtrip through the Northern Perth Basin over the weekend (6-8 Sept), led by Simon Sturrock (Strat Trap), Darren Ferdinando (Murphy Oil), and our very own Amely Allgöwer (MGPalaeo).

The trip focused on the regressive to transgressive, Early Permian sequence exposed along the Irwin River in Coalseam Conservation Park. Between Darren, Simon, and Amely the group integrated sedimentology and ichnofacies with predictive sequence stratigraphic analysis to compare the outcrop to the prospective play in the basin.

On the Friday after AEGC 2019, a group of 27 very punctual geoscientists ranging in age and experience from Cenozoic to Devonian gathered at 8am outside the Crown in Perth and excitedly climbed onto the bus ready for the short drive up to the Mingenew Hotel, which would serve as basecamp for the next few days.

The Pinnacles in Nambung National Park

To break up the drive and show our international visitors some of what Western Australia has to offer, the bus stopped by the Pinnacles in Nambung National Park. The group took some photos of the fascinating landscape before diving into discussion on what exact mechanisms may have formed the Pinnacles. After a lunch stop in Cervantes (which included ice-cream), attendees were treated to a walk out over the stromatolites of Lake Thetis; a small, permanent metahaline lake fed by rain and groundwater. These stromatolites developed during the last 3,000-4,000 years, though the structures they produce have been identified as far back as 3.45 billion years ago in the rock record, making them one of Earth’s ultimate survivors.

By the time the group finished admiring the stromatolites, less than 200 km and one more stop stood between the geologists and their evening beers at the Mingenew Hotel. The picturesque view at Dynamite Bay in Green Head, however, was worth the wait. The low-lying cliffs protect the beach from strong winds, making it a perfect place to stop, enjoy a coffee, and soak in the afternoon colours of the bay.

On Saturday morning, the group boarded the bus with a degree of excitement that only geologists heading to a new outcrop can manage. The outcrops along the Irwin River did not disappoint. The shallowly dipping strata meant participants could walk along the cliff until the Early Permian units of interest were at eye level for easy examination. Discussions at the Irwin River outcrops covered the sedimentary structures, fossils, trace fossils, the environments in which each of the formations were deposited, and their heterogeneity along dip which often leads to confusion when dealing with lithostratigraphic terms. With stunning glacial drop stones, fossil bryozoan, crinoids, corals, and bivalves, plus a large array of inchogenera there was something for everyone.

Sunday morning meant it was time to start the drive back to Perth. Along the way we stopped for a quick look at a Pleistocene reef outcrop, formed by a range of branching, palmate, and horizontal coral during the last interglacial period when the sea was 2.5 m above the present level.

Our international visitors were lucky enough to spot wildflowers, kangaroos, and emus on the drive back, before enjoying the sites of wineries in the swan valley. By the time the group returned to the Crown in Burswood, participants were already hard at work planning the next fieldtrip, and discussing the outcrops seen over the past few days.

Here at MGPalaeo, we would like to extend a huge thank-you to Deidre Brooks for organising the fieldtrip, Terry from Cross Country Charters for getting us to the outcrops safely, the instructors Simon, Darren, and Amely for an excellent trip, and to all the participants for the wonderful company and animated discussions.

Hopefully the stunning outcrops and in-depth discussions have rekindled everyone’s passion for the Perth Basin. It certainly has ours, and we’ve now started planning a Perth Basin integrated core workshop. If you are interested in attending such a workshop (we haven’t sorted out dates yet), please let us know on [email protected].

The Bedout Workshop – a core workshop week full of firsts!

We are extremely pleased to announce that our recent Bedout Sub-basin core workshop was the highest attended core workshop in MGPalaeo’s history, with 46 participants from all over Australia and overseas joining us on our journey through the Lower Keraudren Formation. This much interest in the Bedout Sub-basin meant it was impossible to fit everyone in on the same day, so we had to run the workshop three times! That’s certainly a first for us!

MGPalaeo was lucky enough to be the first company to run a workshop showcasing the sedimentology and palynology of the recently released Roc 2 well, located near to the staggering oil discovery in Dorado 1. To make sure we took full advantage of this opportunity, we incorporated cores from Phoenix 1, Phoenix 2 and Bruce 1 at the same time, as these are the only wells containing core over the Middle Triassic in this area.

MGPalaeo's Bedout Sub-basin core workshopThe nearly 120m of Roc 2 cores were clearly the highlight of the workshop, with some people coming back to have a look at it for a second time. Detailed examination and integration of the sedimentology and palynology produced many surprises and unexpected variations in depositional environments over short intervals. With the integration of sedimentological structures, ichnology and palynology, we were able to differentiate small changes in delta morphologies affecting reservoir quality and TOC content. The cores in Phoenix 1, Phoenix 2 and Bruce 1 were a little bit easier to ‘digest’ with fewer variations in depositional environments. Even so, significant alternative interpretations were presented, taking us from delta top to delta front environments.

It was also the first core workshop where we had a namesake for one of our participants; a short, and in parts quite coarse (in a sedimentology kind of way) get-together that was only interrupted by the occasional fault zone!

We are always looking at how we can improve our workshops, so we were delighted to receive very positive feedback for this one, with the highlight noted as being the integration of sedimentology and palynology. Combining these two disciplines certainly helps create more accurate geological models, and it is something we will keep working on integrating for future workshops.

MGPalaeo's Bedout Sub-basin core workshopMGPalaeo would like to thank all our participants for attending and contributing to our core workshop, and for making it the success it was. We couldn’t have done it without your involvement. We had a great time in the core store sharing our knowledge and listening to alternative ideas, so thank you for joining us on our journey through the Bedout Sub-basin.

MGPalaeo would also like to thank the members of the DMIRS core store staff, especially Paul Stephenson, for their assistance and support in allowing this workshop to happen.

We have more core workshops planned for this year and next, so don’t forget to sign up to our newsletter and receive the announcements first. We also have a range of core workshops available for company internal training that we run on request. And finally, both our comprehensive palynological study and our integrated core study of the Bedout Sub-basin now incorporate Roc-2 data, so please contact us for more information.

See you in the core store!

Last Chance for the Vulcan!

Our Vulcan Sub-basin core workshop is filling up fast but it’s not to late to book your spot. The deadline for signing up is the 15th of August so contact us now and join us on a fascinating journey through 30 cores spanning the Late Cretaceous Puffin Formation to the Triassic plays of the Pollard Formation.

MGPalaeo Vulcan Sub-basin core workshopTo add to this, our Vulcan Sub-basin Comprehensive Core Data Set is also now complete, just in time for the workshop. This mammoth study covers 1.6 kilometres of core from 63 wells spanning an area from Crux 1 in the South-West to Ludmilla 1 in the North-East.

All cored wells within the Vulcan Sub-basin have been reviewed, with more than 200 pages of core descriptions and palaeogeographic maps, and close to 2000 RCA measurements plotted against grain size, lithology, lithofacies and depofacies.

Out of these 63 wells, 25 wells have also been described as follows:
◦ Approx. 270m of cores at 1:70 scale (12 wells)
◦ Approx. 500m of cores at 1:200 scale (13 wells)

This comprehensive core data set is an excellent opportunity to gain an insight into the complexity of the Vulcan Sub-basin and what can be achieved when integrating revised existing palynology and sedimentology at high levels.

Please contact us at [email protected] for more information on the Vulcan Sub-basin core workshop or the ground-breaking multi-client core study, but remember, the deadline for the workshop is the 15th of August!

 

Vulcan Sub-basin – Comprehensive Core Data Set


Join us on our journey through the Vulcan Sub-basin – one of the hottest areas of the North West Shelf!

MGPalaeo’s Multi-client Core Study over the Vulcan Sub-basin is a comprehensive data set covering 1.6 kilometres of core from 63 wells from Crux 1 in the South-West to Ludmilla 1 in the North-East.

All cored intervals were reviewed and photographed during which core condition, cored intervals and brief observations of the core, including depositional environments, were recorded. Existing palynological data over the cored intervals has also been reviewed and refined, and supplemented by analysis of new core samples.

MGPalaeo Vulcan Sub-basin Core Review

Additionally, out of these 63 wells, 25 wells were described at moderate to low resolution, with 270m (approx.) of cores described at 1:70 scale and 500m (approx.) of cores at 1:200 scale. A PDF of each of the core logs, a brief report including depositional models, along with digital grain size, litho- and depofacies data, will be provided as part of the deliverables in this multi-client study.

Would you like to see some of the wells from this study in core? No problem, just come along to our Multi-day Core Workshop.

We will be looking at key stratigraphic intervals, starting with the Late Cretaceous Puffin Formation and finishing off in the Late – Middle Triassic Pollard Formation.

MGPalaeo Vulcan Sub-basin cores

To cope with the significant amount of core present we have split our core workshop into two parts; the first two days will cover the younger parts of the stratigraphy from the Puffin Formation to the Lower Vulcan Formation, whilst the older stratigraphy from the Elang to the Pollard Formations are covered in a separate one-day workshop immediately following.

During the Puffin Formation to Lower Vulcan Formation two-day core workshop, we will focus mainly on the Upper and Lower Vulcan formations, although cores from the Puffin Formation and Echuca Shoals Formation will also be included. A wide range of depositional environments, including seal and reservoir facies are present throughout this part of the stratigraphy and will be discussed in detail, while comparing the changes in environment with surrounding wells.

The one-day Elang Formation to Pollard Formation core workshop concentrates on the older parts of the stratigraphy, covering the Elang, Plover, Malita, Challis and Pollard formations and the changes in depositional environments. New palynological samples add to the complexity of the overall stratigraphy and are discussed throughout the day.

Companies / Individuals will have the chance to sign-up to either one of the workshops individually or for the three days combined at reduced rates.

Contact us now for pricing, more information on our comprehensive Multi-client Study or register your interest for the Core Workshop Series to stay up-to-date with the timing.

Marine Incursions over the Mungaroo Formation

After our successful (and sold-out) Plover Formation core Balthazar 1 MGPalaeo's Mungaroo Core Workshopworkshop, MGPalaeo is excited to announce that we will be running another integrated core workshop later this year.

This time we’ll be looking at marginal marine and marine incursions over the Triassic Mungaroo Fm in the Carnarvon Basin. To spice things up we’ve added a new well since we last ran the workshop. Balthazar 1 has a stunning marine incursion in core – have a look yourself!

We’ve also taken 19 new palynological sample from Balthazar 1, so if you would like to see this flooding surface in core and how the dinocysts look from this and other marine incursions, then come along to the workshop and find out!

Here are the details:

The Plover is Almost Full!

Our two-day core workshop on Variations in Depositional Environments within the Plover Formation gets underway on the 15th of March and is almost sold out. We have a couple of places still available but if you’re planning on coming along, please book your spot before the 5th of March.

Here are the details:

Variations in Depositional Environments within the Plover Formation
Date: 15th 16th March, 2018
Time: 8:00am to 4:00pm
Venue: Core Library DMP, 37 Harris Street, Carlisle

Focusing on the integration of palynology and sedimentology from selected cored wells, predominantly situated in the Jurassic Plover Formation of the Browse Basin.

This two-day core workshop focuses on the integration of palynology and sedimentology from selected cored wells, predominantly situated in the Jurassic Plover Formation of the Browse Basin.

Cores from fourteen wells across the greater Ichthys Field (8 wells) and Poseidon area (6 wells) have been selected for detailed discussions. This will be supplemented with regional palynological data.

The aim is to produce a hands-on workshop interspersed with introductory palynological, ichnological, and image log presentations, along with biostratigraphic exercises. Participants will also be given ample opportunity to examine the cores and initiate palynological and sedimentological discussions that help to correlate and better understand the fluvial, marginal marine and shallow marine systems in these Early–early Late Jurassic Browse Basin successions. After this workshop, each attendee will have a better understanding of the variability present within the Plover Formation and will be able to put this knowledge into direct use in any exploration, appraisal or development scenario.

For more detailed information, please contact Amely Allgoewer ([email protected]), or click here to book your spot.
