Cores are still coming, and both dayshift and nightshift teams are handling them well and taking samples at 500 meters. We are seeing a variation between mudstones, sandy siltstones and layers of coal.
As the drill column was being lowered, the dayshift team hung an info banner on the outside wall of the operation site, so that the locals can learn more about the project's purpose
In order to ensure the safety of the borehole, a decision was made to reduce the diameter of the drill. The cores are still going to come out, only now with a smaller diameter than before.
While the drilling company is working on adjustments to keep the borehole safe, our science team goes into the woods to search for outcrops. However, the tide was high and hid the outcrop. So, our activity turned just into a walk into the açaí woods.
The dayshift team finally got a full day's work after the drill got back from maintenance. Amidst core handling and gas sampling, some porewater were also collected by our expert Thayná.
After a couple of hours under maintenance, the drill got back to work, and still managed to reach 400 m during the night shift. In the last couple of meters, the lithology varied between fine sandstone, siltstone and mudstone.
New members on board. Welcome back Rain Blankenship and Thomás Miranda. They were present at the Acre site and their energy and expertise will be useful at the TADP second site.
We are drilling at 357 meters with good recovery. The mud sometimes becomes firm and dry, and the sand is firm. Here is a core recovered during the night shift at around 345 meters. The grayish portion is very fine sandstone. The greenish one is mudstone, and the reddish one is mudstone cemented by iron. We will assemble this puzzle when we open the core in Minnesota.
Tonight, Marcos Bolognini leads the night shift and performs the downhole geophysical logging. The Sonic (FWS) and Gamma Ray (GR) probes run smoothly. Thanks to Anarda Simões, Dailson Bertassoli, Isaac Bezerra, and the GEOSOL team for your help.
The logistics of the Marajó site are challenging. The distance along the river is longer than expected. However, the work needs to be done, and the probes are on their way using the local boat.
Considering the scientific activities time off, we changed the shift. Farewell, Carol Leite. The project manager Isaac Bezerra had a short break in his hometown. If you visit Belém, enjoy the delicious local dishes and the real Açaí.
The 7" enlargement operations, installation of the 5 3/4" casing, and cement operation, as well as the installation of the BOP, were completely successful. The Marajó site is an artwork and poetry.
A bulk rock sample was collected during the enlargement operations. This is a representative sample from the surface to 265.35 meters depth. It includes a mixture of sediments such as sub-rounded quartz pebbles and gravels, iron-cemented sandstone lithoclasts, pyritized plant remains, and sand of various grain sizes.
An iron duricrust pebble was recovered during the enlargement activities. We will find out where it came from during the Sampling Party at the CSD facilities in Minneapolis.
Activities were paused for maintenance and better performance. Clauses is always attentive to every detail, measuring all efforts for the success of drilling
Safety technician Ricardo Sampaio coordinated the "May Yellow" campaign. This campaign aims to prevent traffic accidents by supporting victims and providing guidance to drivers and pedestrians for safer and more conscious traffic. The engagement of scientists, workers and community is important.
The visit by Lin Li and André Sawakuchi to the Federal University of Pará in Breves has been productive, involving a discussion about the TADP. Acknowledging Prof. Ronaldo for his hospitality is a nice touch.
With the participation of government agents, teachers, students, and locals, the outreach team organizes a workshop to present and clarify the project's objectives to the Bagre community
The Outreach team arrives in Bagre and visits villages, talking to locals to understand the population's reality and areas of interest for geotourism and geoconservation. From right to left: Melqui, Carlos Mazoca and Raquel Romão.
