With technical advances in surface seismic and downhole electrical imaging techniques, it is now possible to not only map the distribution of reservoir sandstones in the subsurface, but to accurately define the orientation of productive fairways, or “sweet-spots”, within the sequence.
Channel sands frequently have favorable reservoir characteristics. Having often been laid down in higher energy settings, they commonly have coarser and better sorted grains, less clay and improved poro-perm characteristics. However, they often have limited lateral extent and shoe-string geometries which make them more difficult to predict in the subsurface.
Understanding land use influence to coastal ecosystems in the Rio Grande de M...Loretta Roberson
The document summarizes a research study on sediment dynamics in the Rio Grande de Manati Watershed and how land use influences riverine inputs to coastal ecosystems. The goals are to relate land use to sediment inputs in the river, analyze river contributions to the coast through suspended sediment, and establish relationships between suspended sediment, turbidity, and sunlight attenuation in the coast. Methodologies include generating a land use map using remote sensing, collecting suspended sediment samples at sites along the river and coast, and using satellites to measure the outfall influence on the coast. The study will help understand sediment generation and transport in the watershed to inform management practices that control sediment inputs to coastal zones.

Otoliths are bony structures in fish that record chemical signatures from the surrounding environment over time. Analysis of otolith microchemistry can be used to identify fish stocks, determine habitat use and migration patterns. Elements like strontium and barium deposited in otoliths vary between freshwater, estuarine and marine environments. This allows distinguishing anadromous fish that migrate between habitats and tracking their movements. Studies have used this technique to study life histories of species in Amazonian rivers and identify nursery areas of herring. Otolith microchemistry is a valuable tool for answering ecological questions about fish.

Seawater and sediment samples will be collected from various depths and sites and analyzed for physical, chemical, and biological parameters to assess quality. Plankton samples will be collected using nets and analyzed in the laboratory.
This study entails the biostratigraphy of benthic agglutinating foraminifera of four wells in the deep water of the Niger Delta. A total of 453 ditch cuttings were analysed for wells A, B, C and D. Eighty-five and 164 ditch cuttings from the intervals of 4900–9920 ft. and 4530–14600 ft. of wells A and well B respectively, while 92 and 112 cuttings from 5760–11400 ft. and 6000–12750 ft. were analysed in wells C and D respectively. These samples were processed and analysed at 60 feet intervals. .
The analysed sections of the wells are composed of shale, mudstones and sand deposited in the upper to lower bathyal environments. The agglutinating foraminifera recovered were fairly well preserved. Total foraminifera percentages recovered from wells A, B, C and D wells are 31%, 34%, 24% and 27% respectively. Marker species were identified and used to erect biozones. The following six agglutinated foraminiferal zones beginning from the oldest have been proposed, Eggerella scrabra Taxon Range Zone, and Ammobaculites strathearnensis–Eggerella scabra, Haplophragmoides narivaensis - Eggerella scabra, Cyclammina cancellata–Ammobaculites strathearnensis, Cyclammina complanata–Glomospira gordiales, Cyclammina cf. minima–Ammobaculites strathearnensis Interval Range Zones. The agglutinated foraminifera assemblages were calibrated to the geologic timeframe by means of planktic foraminifera and calcareous nannofossils. The studied wells penetrated a sedimentary succession of Late Miocene to Early Pliocene age. Taxonomic notes on some of the observed species have also been provided.
This document summarizes loss on ignition (LOI) results from a sediment core collected from Crystal Lake in western Ohio. LOI analysis was conducted on three additional drives from the core to further investigate quasi-cycles in organic material and calcium carbonate levels over time. The results provide evidence of fluctuating organic content between 4-18% over depths of 1200-1550cm. Calcium carbonate levels were highest from 1100-1460cm and decreased below 1460cm, potentially indicating a change in the carbon cycle. Continued LOI and other analyses at this site will improve understanding of past climate changes in the region.
The document discusses various techniques used in paleontology for identifying, excavating, and studying fossils. It describes how paleontologists can identify different fossils based on characteristics like shape, texture, and structure.

Key points include closure stresses on proppant in Argentine reservoirs ranging from 1,000-5,000 psi, use of 3-4 mesh sizes and ceramic-sand blends for shales, potential for coating local sand to improve crush resistance for use at higher closure stresses, and cost-effective proppant alternatives being important to sustainable unconventional development.
A new atlas, providing the most thorough audit of marine life in the Southern Ocean, is published this week by the Scientific Committee on Antarctic Research (SCAR). Leading marine biologists and oceanographers from all over the world spent the last four years compiling everything they know about ocean species from microbes to whales. It’s the first time that such an effort has been undertaken since 1969 when the American Society of Geography published its Antarctic Map Folio Series.
In an unprecedented international collaboration 147 scientists from 91 institutions across 22 countries (Australia, Belgium, Brazil, Canada, Chile, Denmark, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Poland, Portugal, Russia, South Africa, Spain, Switzerland, the UK and the USA) combined their expertise and knowledge to produce the new Biogeographic Atlas of the Southern Ocean. More than 9000 species are recorded, ranging from microbes to whales. Hundreds of thousands of records show the extent of scientific knowledge on the distribution of life in the Southern Ocean. In 66 chapters, the scientists examine the evolution, physical environment, genetics and possible impact of climate change on marine organisms in the region.
Chief editor, Claude De Broyer, of the Royal Belgian Institute of Natural Sciences, said: “This is the first time that all the records of the unique Antarctic marine biodiversity, from the very beginnings of Antarctic exploration in the days of Captain Cook, have been compiled, analysed and mapped by the scientific community. It has resulted in a comprehensive atlas and an accessible database of useful information on the conservation of Antarctic marine life.”

This document summarizes a 1977 palynological study of the Early Cretaceous Naskapi Shale formation in six wells on the Scotian Shelf. The study aimed to correlate the formations between wells based on diagnostic palynomorph species, and compare the local biostratigraphy to formal lithostratigraphic units and European stages. Forty-five samples from the six wells were examined and yielded palynomorph data that was compiled into range charts. The charts allowed correlation and placement of the formations within the Barremian and Aptian stages. The palynology indicates the Naskapi Shale represents a transgressive nearshore marine depositional environment during this period.
This project examined how beach sand composition and tide levels affect the size and age distribution of butter clams. Samples were taken from beaches with varying elevations and sieved to determine sand composition. Statistical analysis found significant differences in clam age and size based on tide level, but not sand composition. The oldest clams were found at higher tide levels, while the youngest were at extreme high and low levels. This data on clam habitat requirements can inform sustainable harvest and farming strategies.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
