Interpreting post-depositional alterations in deep-marine sandstones: Butano Sandstone, central CaliforniaUSA Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-02-01 M. Civitelli, S. Critelli, R.V. Ingersoll
The Butano Sandstone forms part of an Eocene submarine fan deposited in the La Honda basin in central California. The Butano submarine fan has been subdivided into three main facies associations: southern inner-fan deposits, central middle-fan deposits, and northern outer-fan deposits. In spite of homogeneous quartzofeldspathic sandstone composition, these outcrop belts have several compositional and

High resolution sequence cyclostratigraphic modeling of Albian – Cenomanian succession based on statistical, time series and palynofacies analyses in Meleiha Basin in the Western Desert, Egypt Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-02-01 Abdelaziz Mahmoud, Adnan Q. Mahdi, Aboosh H. Al-Hadidy, Walid A. Makled
The Albian-Cenomanian succession in the Western Desert of Egypt represents important source/reservoir rocks. This succession comprises the Kharita and Bahariya formations in addition to the G Member of the Abu Roash Formation. These rock units were studied here using extensive sequence stratigraphic modeling. This model was based on high resolution statistical and time series analyses of electric logs

Facies prediction in a mature oil field of Cretaceous age in the Calumbi Formation (Sergipe-Alagoas Basin, Brazil) by using an outcrop analogue approach Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-02-01 German Meneses Hernandez, Felipe Torres Figueiredo, Liliane Janikian, Mateus do Nascimento Santana, Pedro Victor Oliveira Gomes
Outcrop gamma-ray logging is crucial for understanding subsurface reservoirs, but it is rarely used on outcrops, especially for correlating gamma-ray data from borehole profiles. This case study focuses on a mature onshore reservoir in the Sergipe-Alagoas Basin, Brazil, which is currently discarded by the oil industry. The study used an ideal outcrop (M-17) to gather stratigraphic, sedimentological

Seismic stratigraphy, stacking patterns and intra-clinothem architecture of a Late Holocene, Mud Wedge (Mediterranean Sea) Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-26 Giacomo Dalla Valle, Marzia Rovere, Claudio Pellegrini, Fabiano Gamberi, Fabio Trincardi
Holocene inner shelf mud wedges are important paleoenvironmental archives because they typically contain continuous and extensive sedimentary sequences that can document past changes in sedimentary processes at very high temporal resolution. Here we investigate the fine-scale, seismic patterns of the Late Holocene Adriatic Mud Wedge (AMW), along the western Adriatic margin, to understand the processes

The formation of the Paleocene lacustrine organic-rich shale in the Subei Basin, East China associated with the early late Paleocene event and marine incursions Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-28 Ming Guan, Xiaoping Liu, Zhijun Jin, Wenzhi Zhao, Wei Liu, Leibo Bian, Jin Dong, Xu Zeng, Bang Zeng, Biao Sun, Hanxi Liu, Zibin Wang
The second member of the Funing Formation (Ef) is a Paleocene lacustrine organic-rich shale and has been identified as a primary source rock for both conventional and unconventional oil and gas in East China. It is correlated with the Early Late Paleocene Event (ELPE), a significant temperature inflection point in the Paleocene. However, the impact of the ELPE on the lacustrine organic-rich sedimentation

Reconstructing salinity and redox variation of permian Lucaogou Formation in the Jimsar Sag, the Junggar Basin, China: Combining trace elements and biomarkers as proxies Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-28 Liangrong Qian, Xiujian Ding, Hailei Liu, Wenlong Jiang, Ablimit Yiming, Zhongfa Jiang, Ming Zha
The variation in paleosalinity and paleoredox affect the production and preservation of organic matter. The study of ancient salinity and redox conditions of source rocks is of great significance for the enrichment of organic matter and the exploration of petroleum resources. In this paper, the commonly proxies for paleosalinity and paleoredox are distinguished and discussed. The paleosalinity and

Deciphering the implication of microfacies types and diagenesis on the reservoir quality of the Cambrian sequence in Hassi Messaoud Field, Algeria Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-26 Nassira Mebrouki, Bassem Nabawy, Messaoud Hacini, Mohamed I. Abdel-Fattah
The Cambrian Hassi Messaoud sequence is considered a main reservoir in East Algeria and North Africa. It is well represented in the Hassi Messaoud Basin by four units, from base to top they are R3, R2, R1 (Ra and RI units), and alteration zone. Among these, the Ra is the most important unit due to its reservoir potentiality; it is classified from base to top into D4, D3, D2, ID, and D1 reservoirs,

A review of approaches for submarine landslide-tsunami hazard identification and assessment Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-26 Jean H.M. Roger, Suzanne Bull, Sally J. Watson, Christof Mueller, Jess I.T. Hillman, Andrea Wolter, Geoffroy Lamarche, William Power, Emily Lane, Susi Woelz, Sam Davidson
Submarine landslides can generate destructive tsunamis. Yet their recurrence intervals and tsunamigenic mechanisms are poorly understood, hampering quantification of global exposure and risk. With growing coastal populations and climatic changes, the impacts of tsunami hazards will increase, and will disproportionately affect peoples in underdeveloped countries (e.g., Small Island Developing States)

High-resolution geochemistry in the Lucaogou Formation, Junggar Basin: Climate fluctuation and organic matter enrichment Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-26 Shijie Sun, Bin Zhang, Xiaomei Wang, Wenyao Xiao, Hua Tian, Guiting Hou, Shuichang Zhang
The Permian Junggar Basin was the site of deposition of a large set of organic-rich sediments, among which the Lucaogou Formation is considered an excellent petroleum source bed. High-frequency variation in lithology is a typical feature of the Lucaogou Formation, reflecting the fluctuation of the paleoclimate and depositional environment. The relationship between climate fluctuation and organic matter

Applying cellular automata to dynamic simulation of a tsunamigenic submarine landslide in the South China Sea Mar. Petrol. Geol. (IF 4.2) Pub Date : 2024-01-26 Jose Marie Antonio Miñoza, James P. Terry, Nigel Winspear, James Goff, Vena Pearl Boñgolan
This work presents the first known application of a new approach to tsunami modelling, by linking a discrete cellular automata (CA) dynamic model of a submarine landslide to an off-the-shelf tsunami modelling package. This has the advantage of simulating the temporal evolution of the submarine landslide rather than as a single rigid sliding mass. We first tested that the coupled model was able to satisfactorily
