Early Paleocene Planktic Foraminifers and Stratigraphy, Jaisalmer Basin, Rajasthan
Authors: Kalia Prabha , Rabha Swapna , Kintso Rokosuno 
Published: June 2015

Abstract:
Early Paleocene planktic foraminifera (Zones P1c to P4) from well sections (Sanu, Sam, Tanot, Ram-1, GTF-1) are reported from the Jaisalmer Basin. The Subzone P1c is characterized by the hemipelagic early Danian species Globoconusa daubjergensis, Eoglobigerina edita, Praemurica pseudoinconstans, P. inconstans, Parasubbotina pseudobulloides, Subbotina triloculinoides and Globanomalina compressa. Zone P2 is identified by the total range of Praemurica uncinata and Eoglobigerina spiralis and Zone P3 by the occurrence of Igorina pusilla in association of Morozovella angulata and M. conicotruncata. Larger benthic foraminiferal species, such as Assilina dandotica, are abundant in the interval identified as Zone P4 characterized by Globanomalina pseudomenardii, Morozovella velascoensis, Igorina albeari, I. tadjikistanensis, Subbotina velascoensis, S. triangularis, Acarinina soldadoensis, and Parasubbotina varianta. This indicates a lower P4 stratigraphic range for Assilina dandotica, which was assumed to appear in Zone P5 (= Standard benthic foraminiferal Zone 5). The Paleocene-Eocene boundary was identified based on Acarinina africana and A. sibaiyaensis marking the Zones P5 to E1 interval.
Multiproxy Evidence of Main Deccan Traps Pulse near the Cretaceous-Tertiary Boundary
Authors: Adatte Thierry , Keller Gerta 
Published: June 2015

Abstract:
Recent studies indicate that the bulk (80%) of Deccan trap eruptions occurred over a relatively short time interval in magnetic polarity C29r, whereas multiproxy studies from central and southeastern India place the Cretaceous-Tertiary (KT) mass extinction near the end of this main phase of Deccan volcanism suggesting a cause-and-effect relationship. Beyond India multiproxy studies also place the main Deccan phase in the uppermost Maastrichtian C29r below the KTB (planktic foraminiferal zones CF2-CF1), as indicated by a rapid shift in 187Os/188Os ratios in deep-sea sections from the Atlantic, Pacific and Indian Oceans, coincident with rapid climate warming, coeval increase in weathering, a significant decrease in bulk carbonate indicative of acidification due to volcanic SO2, and major biotic stress conditions expressed in species dwarfing and decreased abundance in calcareous microfossils (planktic foraminifera and nannofossils). These observations indicate that Deccan volcanism played a key role in increasing atmospheric CO2 and SO2 levels that resulted in global warming and acidified oceans, respectively, increasing biotic stress that predisposed faunas to eventual extinction at the KTB.
Late Permian Palynofossils from the Pali Formation, South Rewa Basin, Madhya Pradesh, India
Authors: Ram-Awatar  , Gautam Saurabh 
Published: June 2015

Abstract:
The present paper deals with the palynological analysis of the Middle Pali sediments exposed along the Murna Nala section, Sohagpur coalfield, South Rewa Basin, Madhya Pradesh. Quantitative and qualitative analyses reveal the Dominance Datum (DODs) of Faunipollenites, Striatopodocarpites and Crescentipollenites in association with Rhizomaspora, Distriatites, Dicappipollenites, Gondisporites, Scheuringipollenites, Densipollenites, Sahnites, Parasaccites, Platysaccus, Plicatipollenites and Potonieisporites. The First Appearance Datum (FADs) of key taxa (e.g., Arcuatipollenites ovatus, Lundbladispora brevicula, Alisporites asanolensis, Goubinispora morondavensis and Weylandites circularis) suggest conclusive evidence for a Late Permian age. The present palynoassemblage of Pali Formation is indicative of palynozone R-1B of Raniganj Formation in Damodar Basin (Tiwari and Singh, 1986). Hence, the Murna Nala sediments have been dated Late Permian in age, which correlates with the Pali Formation (Middle Member) in the South Rewa Basin.
An Evaluation of Carbonaceous Metaphytic remains from the Proterozoic Singhora Group of Chhattisgarh Supergroup, India
Authors: Babu Rupendra , Kant Singh Veeru 
Published: June 2015

Abstract:
Proterozoic grey to khaki grey shales of three localities from the Saraipali and Chhuipali Formations of the Singhora Group, Chhattisgarh Basin, contain diversified, exceptionally well preserved compressions and impressions of planktic and benthic meso-megascopic uni-multicellular eukaryotic metaphytes and rare prokaryotic thin films. These vegetative forms are millimeter-centimeters in size and varied shapes viz. straight to curve leafy-discoidal-palmate with and without parastem=holdfasts. A few are dichotomously branched and compactly entangled with numerous filaments. The present enigmatic remarkable thalloid fossil assemblage includes 19 taxa (viz. Beltina danai, Changchengia stipitata, Chuaria circularis, Enteromorphytes siniansis, Eopalmaria prinstina, Longfengshania fusiformis, L. ovalis, L. spheria, Palaeochorda vindhyansis, Phascolites imparilis, Proterotaenia montana, Siphonophycus solidum, Sitaulia minor, Tawuia dalensis, Tuanshanzia fasciaria, T. lanceolata, T. platyphylla, Tyrasotaenia podolica and Leiospheridia sp.) belonging to Cyanophyta, Chlorophyta, Phaeophyta, Rhodophyta and Xanthophyta algae. The morphology and associated characters of these diversified new fossils indicate the advent of eukaryotic multicellularity in the latest Palaeoproterozoic and polybiont algal diversity or paraphylly probably at two age intervals (1750 Ma and 1400 Ma), which mark evolutionary trends in Proterozoic life. The assemblage reveals an oscillating theromcline, congenial environment and subtidal-intertidal conditions within a photic zone for the two facies deposits in the Singhora Group.

SPILLTRACK - A Web-Based Tool to Help Managing Contingency in Offshore Oil and Gas Operation
Authors: Marques da Cruz L. M. , Pellegrini J. A. , dos Santos F. A. , Fragoso M. R. , Rinaldi F. L. 
Published: June 2015

Abstract
Oil and Gas offshore operations are challenging procedures not only due to its own nature but also due to the environmental conditions. Metocean conditions can really harm the operations and make what is already a tricky procedure to become a nightmare.
An intrinsic feature of this type of operation is the management of the regular and explicit interaction with the environment such as the vessel transit from the coastal base to the rig location; drilling effluent discharges at the sea; controlling the best window regarding metocean conditions to advance or postpone one or more procedures; amongst others.
Besides the regular interaction, operators must also deal and be planned to deal with possible incident conditions. Those situations vary from simple failures in any equipment up to events of man at sea and also the drastic situation of a pollutant spill at the sea.
In this scenario, SPILLTRACK was designed. The system is modular, integrating all metocean data, vessel traffic information (vessel tracking system), Search and Rescue procedures (SAR model built inside the system), regular discharges forecast and pollutant spill forecast.
All this information is put together in the same platform which also deals with the environment. It allows for instance, managing and helping all contingency procedures during a real incident and also in drill exercises.
GIS features are also available in the system mostly to manage the impact and help the contingency actions.
The access to the system is made by login and password and can be done at different regions at the same time, with no need for any type of hardware interference in the operators’ facilities. In other words, all the information is available together at the office, at the rig location and anywhere else the decision makers thinks is important.
SPILLTRACK has been used successfully in offshore operation since 2009. Particularly in high sensitive areas, the system is able to manage and control the contingency actions in order to avoid impacts in coastal and offshore sensitive areas.
Water Management for Tight and Shale Reservoir: A Review of What Has Been Learned and What Should Be Considered for Development in Argentina
Authors: Carlos Bonapace Juan 
Published: June 2015

Abstract
This work builds on Bonapace et al. (2015), specifically discussing shale reservoir information related to several tight reservoirs in Argentina.
Hydraulic fracturing has been ongoing in Argentina since the 1960s. The first treatments were performed using oil-based fluids. Throughout the years, new water-based fluids were introduced, as well as alcohol-water mixture fluids to foams, based on the reservoir requirements, economics, and safety and environmental issues. Currently, more than 95% of hydraulic fractures performed in the country are performed using aqueous-based fluids.
In the last 10 years, exploration and development has begun for tight gas reservoirs and more recently several shale plays. To achieve commercial production, this type of reservoir requires extensive hydraulic fracturing applications which use large volumes of water. From 2004 to present, various exploration techniques have been performed in different reservoirs, such as tight formations at Lajas, Punta Rosada, Mulichinco (Neuquén Basin); Potrerillos (Cuyo Basin); D-129 (Golfo San Jorge Basin) and shale plays at Los Molles, Vaca Muerta, Agrio (Neuquén Basin), Cacheuta (Cuyo Basin), and D-129 (Golfo San Jorge Basin).
This paper discusses aspects of water logistics necessary during the well completion phase, fracture treatment designs applied within these various unconventional reservoirs, and laboratory studies performed on flowback and produced waters to help evaluate their potential for use and/or reuse. The primary focus here will be related to various parts of the water cycle for these projects. Stimulation and water sources are presented as detailed information concerning the type of stimulation performed in these reservoirs, volume of water, treatment types, fracturing fluids, additives used, and physical-chemical characteristics of various freshwater sources used.Logistics are discussed for water storage and transport for single and multiple well pads.Reuse of flowback and formation water addresses laboratory testing of various flowback and formation water and/or blends (freshwater and flowback water), treated and untreated including:–Physico-chemical characteristics of water (flowback and produced) from various wells.–Formation sensibility testing with flowback water from various tight and shale formations and usage possibilities.–Impact on proppant packs of floculants generated in nontraditional waters at various pH values.–A new low-residue CMHPG-metal crosslinked fracturing fluid formulated using no traditional water, i.e., untreated with high total dissolved solids (TDS).

Published: June 2015

Abstract
After the concession of marine blocks for exploration and production of oil and natural gas in the last decade, oil industries activities became to exert greater pressure on the marine and coastal environments of Brazil. The BM-J-2 block is located about 20 km away from the coast of Una, Canavieiras and Belmonte municipalities in the Southern region of Bahia State. This region is constituted by important coastal marine ecosystems, some of them protected by law. This context makes this area mentioned sensitive to impacts from potential oil spill accidents. This work aims to map the environmental sensitivity to oil spills, using remote sensing and in situ data. Therefore, the production of maps representing littoral sensitivity index (LSI) in different hydrodynamics modeling scenarios is important for the implementation of contingency and emergency plans. Moreover, regional studies of geomorphology, land cover and land use were also used to construct the LSI charts. Those revealed different levels of environmental sensitivity to oil spill LSI ranging from 1 (lowest sensitive) to LSI 10, depending on the hydrodynamic conditions. This study shows the importance of considering the spatial and seasonal variability of hydrological, oceanographic and atmospheric processes in order to understand of environmental sensitivity of the coastal ecosystems.

Modeling the Optimal Trajectory of a Skimmer Ship to Clean Oil Spills in the Open Sea
Authors: Gomez S.. , Ivorra B.. , Glowinski R.. , Ramos A. M. 
Published: June 2015

Abstract
Oil spill contamination in the open sea has been at the origin of some of the worst environmental disasters. One of the major cleaning techniques is the use of skimmer ships that contain various pumps distributed along its waterline to suck the oil from the surface of the water directly into storage units. We want to improve this process. We developed a model to simulate the effect of the skimmer ship on the evolution of the oil spill. This model, based on a finite volume approximation of an advection-diffusion-reaction equation, considers: the motion of oil spots resulting from the movement of the source of contamination; the diffusion and transport by wind and sea currents; and the phenomena associated with the action of the skimmer ship, assuming that it follows a pre-assigned trajectory. We introduce a nonlinear diffusion term to obtain finite speed diffusion. Also, we use an absorbing boundary condition, to account for the oil exiting the computational domain. To reduce numerical artificial diffusion, we use second order numerical schemes to discretize the advection terms. We also apply splitting schemes to decrease the computational complexity. To improve the whole process, we optimize the trajectory of a skimmer ship to maximize the amount of recovered oil during a fixed period of time, using an optimization method. The novel approach we advocate here is validated by comparing our numerical results with real life measurements from the Prestige spill, which took place in Spain in 2002. We were able to reproduce the satellite image of the spot after 4 days of pollution. We also prove that the optimal trajectory we get cleans the area near the coast up to 55 percent before the Prestige ship broke up. This percentage was improved to 88 percent by using a second ship on the entire area.

Published: June 2015

Abstract
Biodiversity management in exploratory projects, especially in remote areas, includes risk analysis and decision-making with little information available. In order to optimize the effort and manage business risks, biodiversity information from previous studies and secondary sources and recent data resulting from field work of the companies should be considered valuable (e.g. biodiversity and environmental impact studies). The objective of this project was to create a biodiversity information system enabling the effective resources management as well as activities planning, through an understanding of the different attributes in the landscape and the ecosystem services analysis, integrating the multidisciplinary knowledge within the framework of a spatial analysis.
Biodiversity information can be organized for developing biodiversity conservation strategies and for managing oil and gas projects' life-cycle, as long as it is available and logically structured. Biodiversity data is usually in reports where its consolidation and management is not easy. Geographic Information Systems rise an opportunity; geospatial data (georeferenced information) can be converted in a digital format and the management improved. For this case study, we selected the variables needed to be included in the biodiversity database, reviewing the quality of the data, its usefulness for a potential future use, the availability, versatility of biodiversity consultations and the data generation costs and in the right time.
The conceptualization and structure of the biodiversity geodatabase developed in this project allows the integration and spatial analysis of biological, social, environmental and engineering information of exploratory projects, becoming an important tool to answer questions and solve problems. With the aim of speeding up the analysis and the subsequent use or interpretation, important considerations for the data standardization and systematization were addressed from participatory workshops with different disciplines (as engineering, community relations, and safety and environment). This database helps data management improvement and gap analysis as well as biodiversity data adquisition in Oil & Gas projects. This tool contributes to energy companies in the selection of biodiversity and ecosystem services performance indicators; as well as their subsequent monitoring and the implementation of biodiversity actions plans.
Short-term effects of nicotine on orthodontically induced root resorption in rats
Authors: Li Jing , Wang Xuxia , Li Na , Zhenga Dehua , Su Yuran , Zhang Jun 
Published: June 2015

ABSTRACT

Objective:
To investigate the effect of nicotine exposure on root resorption in an in vivo rat model of orthodontic tooth movement (OTM), and its association with odontoclastogenesis and receptor activator of nuclear factor-kappa B ligand (RANKL) expression.

Materials and Methods:
Forty-eight 10-week-old male Wistar rats were divided into three groups. The negative control group was untreated. The left maxillary first molars in the nicotine-treated group and the positive control group received OTM with an initial force of 0.6 N in the mesial direction. Also, the nicotine-treated group received intraperitoneal injection of nicotine at 7 mg/kg per day. After 21 days, the rats were humanely killed. Eight rats from each group were randomly chosen for crater volume analysis by micro-computed tomography. For the remaining eight rats in each group, specimen slices were generated for histologic examination to determine the odontoclast number and the mean optical density value of RANKL.

Results:
The resorption volumes in the nicotine-treated group were significantly larger than those in the control groups. Also, the nicotine-treated group displayed significantly higher number of odontoclasts and elevated RANKL expression compared to the control groups.

Conclusions:
In an in vivo rat model, nicotine exposure promotes odontoclastogenesis and RANKL expression, evoking aggravated root resorption during OTM.
The response of fabric variations to simple shear and migration recrystallization
Authors: Kennedy Joseph H. , Pettit Erin C. 
Published: June 2015

AbstractThe observable microstructures in ice are the result of many dynamic and competing processes. These processes are influenced by climate variables in the firn. Layers deposited in different climate regimes may show variations in fabric which can persist deep into the ice sheet; fabric may ‘remember’ these past climate regimes. We model the evolution of fabric variations below the firn–ice transition and show that the addition of shear to compressive-stress regimes preserves the modeled fabric variations longer than compression-only regimes, because shear drives a positive feedback between crystal rotation and deformation. Even without shear, the modeled ice retains memory of the fabric variation for 200 ka in typical polar ice-sheet conditions. Our model shows that temperature affects how long the fabric variation is preserved, but only affects the strain-integrated fabric evolution profile when comparing results straddling the thermal-activation-energy threshold (∼−10°C). Even at high temperatures, migration recrystallization does not eliminate the modeled fabric’s memory under most conditions. High levels of nearest-neighbor interactions will, however, eliminate the modeled fabric’s memory more quickly than low levels of nearest-neighbor interactions. Ultimately, our model predicts that fabrics will retain memory of past climatic variations when subject to a wide variety of conditions found in polar ice sheets.
