Abstract.
The dipole sonic scanner tool run in the subhorizontal geothermal (SH) well of Grigny GGR5 in April 2023 provided interesting images of a reflector population oblique to the main bedding and attributed to oolite progradation located in a depth interval from 4 to 7m below the SH drain, without intersecting the borehole [Naville et al. (in...
The “Calcaires du Barrois” Formation is a succession of dominantly micritic limestone of Kimmeridgian to Tithonian age, outcropping in the eastern part of the Paris Basin. This is an active karstic aquifer of main interest for the Andra (French National Agency for Radioactive Waste Management) who study the feasibility of a deep geological reposito...
This presentation was initially prepared for the SPWLA 2023 Fall Topical Conference "SEE AND HEAR THE FORMATION: EXPLORING THE SYNERGIES BETWEEN BOREHOLE IMAGING AND BOREHOLE ACOUSTICS"/ LOOKING BEYOND THE WELLBORE, jointly hosted by the Acoustics and Borehole Imaging SIGS ( Special Interest Groups) held in November 8-9th in Houston.
A short abst...
We investigate herein the lateral and vertical lithological heterogeneities of the Lower/Middle Oxfordian deposits (“Terrain à Chailles” and “Marnes des Eparges” formations) in the north-eastern Paris Basin. This new detailed stratigraphic framework documents the evolution at high resolution of an outer ramp based on regional correlations in order...
Recent developments of carbon capture and storage and geothermal subsurface prospects in the Middle Jurassic limestone of the central part of the Paris Basin have rejuvenated interest in the world class outcrops of the Bathonian Oolithe Blanche Formation on the southeastern edge of the Basin. Here, ooid-bioclast grainstones occur as large-scale (10...
This study showcases the value of drone photogrammetry in creating a meter-scale geological model of complex carbonate geobodies. Although drone photogrammetry is now commonly used for modeling the sedimentary facies and architecture of sandstone outcrops, its use is not widespread in creating geomodels of carbonate geobodies. Drone photogrammetry...
Major decollements located within buried overpressured shale commonly develop in thrust fronts, accretionary prisms and sedimentary deltas controlled by gravity tectonics. In seismic data, it is possible to observe only large scale deformation of what is commonly designed as mobile shale but the precise geometry and the dynamic evolution of these b...
The Albian Mauddud Formation is a prolific reservoir in Kuwait and nearby countries such as Iraq and Iran but has received far less attention than the under‐ and overlying units (the Aptian Shu'aiba and Cenomanian Mishrif Formations). Detailed reservoir characterization studies of the formation are required to support field development and improved...
The Upper Slochteren Sandstones of the Rotliegend Formation (ROSLU) were studied in offshore Netherlands to evaluate the impact of diagenesis, and more particularly of carbonate diagenesis, on sandstone reservoirs. An integrated study applying petrography, geochemistry (SEM-EDS, XRD, C & O stable isotopes, Sr isotopes), and fluid inclusion measurem...
The aim of this study is to decipher the respective influences of geodynamic and climate disturbances at the Jurassic/Cretaceous boundary on sedimentary facies and carbonate diagenesis in a stable intracratonic basin using isotopic geochemistry and subsidence quantification. Fourteen lithofacies were deposited in a (1) carbonate platform and (2) a...
Nodular bedding is a very common fabric in the Cretaceous carbonates of the Middle East, and possibly even more so during the Albian to Turonian period. This style of bedding is mostly considered to be a result of bioturbation, involving Thalassinoides ichnotraces, and can be developed in open marine carbonates, as well as shallow marine lagoonal t...
Nuclear magnetic resonance (NMR), stable isotope geochemistry of micro-sampled cores, NMR well-logs and 3D modeling are used to investigate the carbonate permeability-porosity heterogeneity along 230 m-thick limestones of the Paris Basin. Despite the global low porosity and permeability of the limestones, two aquifers units with porosity greater th...
It is usually very difficult to identify and quantify the relative influence of tectonics, eustasy and climate on carbonate system evolution from sedimentary records. In order to improve our understanding of these mechanisms, we have traced for the first time, the evolution of the eastern Paris Basin platform throughout the entire Jurassic period....
Several diagenetic models have been proposed for Middle and Upper Jurassic carbonates of the eastern Paris Basin. The paragenetic sequences are compared in both aquifers to propose a diagenetic model for the Middle and Late Jurassic deposits as a whole. Petrographic (optical and cathodoluminescence microscopy), structural (fracture orientations) an...
The diagenesis of the Mishrif Formation in the Rumaila field was studied along seven
cored wells, in a well defined sequence stratigraphic framework, integrating petrography, geochemistry and fluid inclusion analyses, with the aim to define its impact on the distribution of reservoir properties. Early diagenetic phases associated to the sequence bo...

The French National Agency for Nuclear Waste Management (Andra) has conducted investigation and modelling programs within the project of a deep geological disposal of radioactive waste in the Meuse/Haute-Marne region. The potential host formation for the French high and intermediate level and long lived radioactive waste is a thick Callovo-Oxfordia...
A detailed chemostratigraphic and biostratigraphic study was performed on the upper Cretaceous Mishrif formation of the Rumaila field, Southern Iraq. Eleven historical cores were selected and sampled for δ13C, 87Sr/86Sr and biostratigraphic analysis to complement the detailed sedimentological descriptions of the cores. This data taken across the fi...
Reconstructions of the Middle and Late Jurassic Sea Surface Temperatures (SST) of western tethyan ocean display short-term changes (0.5 m.y. to 1 m.y.). Recent shallow-marine carbonate systems are potentially very sensitive to climatic variations, as shown during quaternary period (Deschamps et al., 2012). In contrast, in ancient sedimentary system...

Compelling physical evidence for a Late Aptian lowstand with an amplitude of at least 50 m is presented in subsurface seismic and core data from the Arabian Plate. Biostratigraphic dating indicates that the fall and rise bracketing this lowstand were rapid, and that the lowstand lasted for around 5 ma with distinctly cyc...
Within its scientific program devoted to the feasibility of a high level radioactive waste facility in the Callovo-Oxfordian argillaceous rock (COx) of the eastern Paris Basin, Andra has conducted an extensive characterization of the Oxfordian and Dogger limestone formations above and below the COx. More than 25 wells were dedicated to the hydrogeo...

Les objectifs sont de (1) préciser le timing des changements paléo-environnementaux s'opérant durant cette période, de (2) contraindre l'architecture stra...
The diagenesis and fluid system evolution of outcrop analogues of potential sub-thrust Cretaceous carbonate reservoirs in the Musandam Peninsula, northern United Arab Emirates, is reconstructed during the successive stages of the Oman Mountains development. Detailed petrographic and geochemical analyses were carried out on fracture cements in limes...
Examination of petrophysical properties (acoustic velocity, porosity, permeability, and density) and petrographical characteristics (texture, facies composition, and diagenesis) of more than 250 core plugs from the Middle Jurassic carbonates of the eastern Paris Basin provides insights into the parameters controlling acoustic velocities in relative...
Two main events of dolomite formation were identified along the southern border of the Late Jurassic Musandam carbonate platform of the UAE. The first dolomitisation phase (type 1) was restricted to specific stratigraphic layers in Jurassic platform limestones that were subsequently brecciated by mass flow and collapse processes on the platform mar...
A regional sequence stratigraphic model is proposed for the Oligo-Miocene Asmari and Pabdeh Formations in the Dezful Embayment of SW Iran. The model is based on both new detailed sedimentological observations in outcrops, core and well logs, and an improved high-resolution chronostratigraphic framework constrained by Sr isotope stratigraphy and bio...
A regional sequence-stratigraphic model is presented for the Barremian to Lower Albian sedimentary systems of southwest Iran, based on seismic-scale outcrop sections, and constrained by new biostratigraphic and chemostratigraphic age dating (ammonites, planktonic forams, orbitolinids and carbon and oxygen isotope curves). This study proposes a fund...

The essential biostratigraphy of the Asmari Formation was outlined in the early 1950 s and thereby the only published record of the biostratigraphy before the Asmari Formation was formally described in the mid 1960 s. The traditional Iranian biostratigraphy is based on unpublished reports. Unfortunately, these reports were written in a period when...
A regional sequence stratigraphic model is presented for the Barremian to Lower Albian sedimentary systems of southwest Iran. Illustrated with nine seismic scale outcrop sections, and constrained by new biostratigraphic and chemostratigraphic age dating (ammonites, pelagic forams, orbitolinids and carbon and oxygen isotope curves), it proposes a fu...
A sequence stratigraphic model is proposed for the Oligo-Miocene Asmari and Pabdeh Formations in the Dezful Embayment of South-West Iran.

Oxygen isotope data from biostratigraphically well-dated oyster shells from the Late Jurassic of the eastern Paris Basin are used to reconstruct the thermal evolution of western Tethyan surface waters during the Early Oxfordian–Early Kimmeridgian interval. Seventy eight oyster shells were carefully screened for potential diagenetic alteration using...
Hydrothermal dolomite (HTD) reservoirs are well-known from exploration and development of hydrocarbon plays in the Middle East. Petroleum geoscientists query for means to model the related reservoir properties. This contribution describes the field geometry, petrography and geochemistry of hydrothermal dolomitisation fronts (Late Jurassic, Lebanon)...
The Oxfordian and Kimmeridgian carbonates of the eastern edge of the Paris Basin display poor reservoir properties (Φ < 15% and K < 0.1 md). The petrographic investigation and the resultant paragenetic sequence show that this is due to extensive precipitation of 2 types of almost synchronous blocky LMC (Low Magnesian Calcite) cements during mesogen...

Modelling Fluid-Rock Interaction Induced by the Percolation of CO2-Enriched Solutions in Core Samples: The Role of Reactive Surface Area - Understanding the fate of CO2 disposed in aquifers or depleted hydrocarbon fields is partly based on the use of reaction-transport models, able to predict the possible interaction between acidified waters and th...
A sedimentological and facies sequence study, coupled with geochemical analyses (Sr, Mg, Fe, Mn and δ18O) was made on a core (Ravières, Yonne; south-east Paris Basin, France) in the Bajocian-Bathonian carbonate-shelf sedimentary succession. By studying the strontium variations, geochemical cycles can be correlated to transgressive-regressive sedime...
Questions
Question (1)
Recently, a fashion developed to post preprints on RG or other web media.
As a reminder preprints are manuscripts, thus submitted research that did not underwent the reviewing process.
This is a way of sharing research faster would say some. Indeed, we are unfortunately living in an accelerating world, and science does not stay alongside the road.
However, I see here some reasons to doubt about the possible benefits of posting preprints:
· The benevolent work of the associated Editors and Reviewers is somewhat non-respected, denigrated. It is already sometimes difficult to find some reviewers, and such lack of consideration may lead to really loose the interest for reviewing.
· Ideas or findings in preprints are spread away from their initial scientific domains. For geology (my domain), this may not be a critical problem. But for the medical domain, and overall nowadays, spreading non-quality checked ideas/concepts/results may have some consequences. If the manuscript is rejected, then only the authors are really aware. But the diffusion of the ideas/concepts/results that are rejected is done. This can lead to serious issues.
· There is a risk of plagiarism-related problems. As illustrated by a case raised in a question here on RG, ideas/concepts/results are shared with a community. The manuscript can be rejected or necessitate significant revisions, and then during this period, others may have time to re-bake the ideas/concepts/results of the initial preprint and publish them faster somewhere else. A game of “table tennis prosecution for plagiarism” may then start.
Meetings, conferences are the places to introduce some advances, some “half-baked” ideas (as would have said R. Bathurst), and they should continue to play this role. I think we should let the peer-review process to do its job, but I may be wrong.
Ideas, comments, all welcome!
