Hydrocarbon Exploration Activities Offshore Cyprus.ppt
The document summarizes hydrocarbon exploration activities offshore Cyprus and plans for developing a natural gas discovery. It notes that Noble Energy discovered an estimated 7 trillion cubic feet gas field in 2011 (Block 12) and plans to conduct appraisal drilling in 2013. It outlines next steps for upstream development, pipelines to transport gas to Cyprus by 2017-2018, and plans to establish an onshore LNG plant by 2019 to export gas to Europe and beyond. The discovery could significantly change Cyprus' energy profile if additional discoveries are made through a second offshore licensing round.
Ore_Deposits_and_Ore_Forming_Processes.ppt
This document discusses key concepts related to ore deposits and ore-forming processes. It defines mineralization as the geological formation of economic minerals in a lithological unit through natural earth processes. For a mineralization to be considered a mineral deposit, it must meet minimum thresholds for metal quantity and grade. Ore deposits are classified based on characteristics like host rock, mineral assemblage, size, and geological formation process. Metals are sourced from crustal or mantle rocks, transported by aqueous fluids complexed with ligands, and concentrated at deposition sites where drastic changes in pressure, temperature, or fluid composition occur. Driving forces include heat from volcanic or plutonic activity and fluid flow influenced by topography or geothermal gradients.

The document discusses subaerial unconformities visible in outcrops and provides examples from various locations around the world. Key criteria to identify subaerial unconformities include evidence of exposure like paleosols, erosion and truncation of underlying strata, paleotopography, and onlap of overlying strata. Photos show unconformities with regolith development, karst features, and basal conglomerates that onlap eroded surfaces. Forced regressive surfaces of marine erosion are also discussed and depicted in outcrops showing scoured contacts and shoreface sandstone wedges.

The document describes several landforms produced by wave erosion along coastlines, including headlands, bays, wave-cut notches, wave-cut platforms, arches, caves, stacks, and blowholes. Headlands are areas that jut out into the sea, often ending in cliffs, while bays are wide curved inlets. Wave action can erode cliffs from below, forming platforms, notches, arches that eventually collapse into stacks and stumps. Blowholes form through joints in cliff rocks exposed to hydraulic action inside wave-eroded caves.
Formation of headlands and bays.ppt
Waves eroding a coastline of varying rock resistance will form headlands of harder rock separated by bays in weaker rock. Landforms produced by wave erosion include headlands, bays, stacks, caves, arches, pillars, and wave-cut platforms and notches. Caves can develop into blowholes if joints in the rock connect the cave to the cliff top.

The document describes several landforms produced by wave erosion along coastlines including:
- Stacks, which are pillars of rock isolated from the cliff due to wave erosion.
- Headlands, which are parts of the coastline that jut out into the sea, often ending in cliffs.
- Bays, which are wide curved inlets formed along coastlines with weaker, more erodible rock.
- Arches and caves, which are openings formed when waves erode through headlands or into cliffs.

Waves erode cliffs and headlands through various processes, forming different coastal landforms. Caves form where waves attack both sides of headlands. Arches may form if caves erode all the way through. Stacks and stumps are left when arches and stacks eventually collapse. Over time, this differential erosion of harder and weaker rocks creates a series of alternating headlands and bays along the coastline.
Formation of headlands and bays.ppt
This document describes several landforms produced by wave erosion along coastlines:
- Headlands jut out into the sea at the end of cliffs. Bays form sheltered inlets in weaker coastal rocks between headlands.
- Arches form when waves erode caves completely through headlands. Stacks are isolated pillars that remain when arches collapse.
- Other landforms include caves undercut at the base of cliffs, wave-cut platforms of gently sloping land left after cliff retreat, and blowholes which form when joints in cliff rocks connect eroded caves to the surface.

Stratigraphic principles and sequence stratigraphy are methods used to analyze sedimentary rock layers and impose a temporal dimension. Key concepts include:
- Steno's laws of superposition, original horizontality, and lateral continuity which describe how sedimentary layers are deposited.
- Sequence stratigraphy subdivides strata using surfaces that represent changes in relative sea level, including sequence boundaries, maximum flooding surfaces, and systems tracts like transgressive and highstand.
- Facies describe the characteristics of sediment deposited in different environments, and sequence stratigraphy studies the geometric relationships between facies belts to interpret depositional history.

Submarine canyons cut across continental shelves and slopes, carrying sediment from rivers and coastal areas to deep ocean basins. Submarine fans form at the mouths of canyons, accumulating sediment across the continental slope in a fan-shaped pattern. Sediment transport within submarine fans occurs through various mechanisms like debris flows, density currents, and turbidity currents, resulting in deposition of turbidite sequences that can be studied to understand ancient submarine fan environments.

The objectives are to identify nutrient sources to the aquifer, characterize hydrologic transport processes using modeling, and match nitrate concentrations in springs using the model. The study area includes the Dougherty Karst Plain where the Floridan Aquifer is recharged through sinkholes and rivers. A MODFLOW model is being used to simulate nitrate tracking from recharge areas and calibrate to spring discharge concentrations. Local grid refinement is being added to improve flow path and travel time estimates in key springs.
vdocument.in_unit-1-introduction-to-sedimentology-and-stratigraphy.pptx
Sediments form through the weathering and erosion of rocks, followed by transportation and deposition. There are three main types of sediments: mechanical (clastic), chemical, and organic. Sedimentary rocks form through the compaction and cementation of sediments via the process of diagenesis. Sedimentology involves the study of sediment formation and depositional environments, while stratigraphy examines the temporal and spatial relationships between sedimentary strata. Key methods used in sedimentology include facies analysis, particle size and shape analysis, lithological analysis, and stratigraphic mapping and description.
vdocument.in_petrophysical-properties-of-reservoir-rocks.pptx
This document discusses key petrophysical properties of hydrocarbon-bearing reservoir rocks including porosity, permeability, saturation, and capillarity. It defines porosity as the ratio of pore space to total volume, permeability as the ability of rocks to allow fluid flow through interconnected pores, saturation as the volume of pore space occupied by a fluid, and capillarity as the pressure difference between fluids across curved interfaces in rock pores. Accurate analysis and modeling of these petrophysical properties is important for estimating petroleum reserves and recovery efficiency from reservoirs.
vdocument.in_sedimentary-geology-geos-240-chapter-6-facies-analysis.ppt
This document provides an overview of facies analysis and depositional environments in sedimentary geology. It discusses different facies interpretations of successive units in non-marine sandstones, including planar and trough cross-bedding, asymmetric scour surfaces, and rippled sandstone and mudstone. It also examines a transect of a Permian reef margin and hierarchy of depositional units, including migrating dunes, changes in hydraulic regime, lag accumulation, bar migration, channel erosion, and allogenic events driven by tectonics, eustasy, climate. Adjacent environments can result in vertical successions with different sedimentary structures.

formation pressure (2).pptx
The document discusses various methods used to prevent sloughing during well drilling operations. Specifically:
1. Circulating refrigerating fluid through the well below the freezing point of the formation to freeze it and prevent sloughing.
2. Circulating brine through the well below the freezing point of water to freeze the formation.
3. Circulating mud-laden fluid through the well below the freezing point of water to freeze the formation.
4. Circulating an emulsion through the well below the freezing point of water to freeze the formation.
5. Causing fluid to flow into the well to seep into the formation, then circulating it below the freezing point of water to freeze the formation
abnormal pressure.pptx
The document discusses methods for drilling wells through formations containing sloughing shale to prevent borehole collapse.
It describes 6 methods:
1. Circulating refrigerated fluid through the well to freeze the formation, with the refrigerant having a freezing point below that of the formation fluid.
2. Circulating brine through the well and cooling it to freeze the formation, with the brine's freezing point below that of water.
3. Circulating mud-laden fluid through the well in the same way as method 2.
4. Circulating an emulsion through the well in the same way as methods 2 and 3.
5. Causing fluid to flow into the well to contact
sloughing formation.pptx
The document discusses the problem of sloughing shale during drilling operations. Sloughing shale occurs when the mud weight is not adequate to control subsurface pressure or the mud salinity causes undesirable osmotic pressure, leading to borehole collapse and stuck drill pipes or bottom hole assembly (BHA). It states that sloughing shale is one of the mechanical issues that can cause stuck pipes. The author provides a personal anecdote about experiencing BHA getting stuck in sloughing shale for the first time and seeing large cuttings, which was shocking. While shale formations can be drilled quickly when conditions are right, sloughing shale turns it into a stressful problem similar to kicks, losses, and other drilling hazards. Close
Carbonate lithofacies.ppt
This document discusses carbonate sedimentology and classification. It summarizes two early carbonate classification systems by Dunham (1962) and Folk (1962). It also notes that while interpretation techniques used for clastic reservoirs can be applied to carbonates, carbonates differ in their importance of biogenic processes and susceptibility to diagenesis. The document stresses that the ultimate goal is understanding carbonate lithofacies and correlating them with well log and core data.

It outlines carbonate classification schemes by Folk and Dunham and notes that carbonates can exhibit all primary sedimentary structures seen in clastics as well as unique biogenic and diagenetic structures. The ultimate goal of carbonate sedimentology is discussed.
Mudstone facies.pptx
1. The document discusses different types of deltas including braid deltas, fan deltas, and their subfacies.
2. Braid deltas form in lacustrine basins where the slope is gentle in the short axis direction. Fan deltas form where rivers enter lakes at a steep slope and transition to braid deltas where the slope becomes more gentle.
3. Fan delta subfacies include the topset (fan delta plain), foreset (fan delta front), and front (fan) delta. The foreset is the most developed part and contains subaqueous distributary channels and front bars.
conglomerate facies.pptx
The document discusses the classification of bounding surfaces and lithofacies in continental deltas. It divides bounding surfaces into 6 hierarchical levels that control sedimentation and reservoir development. Continental lacustrine basin deltas can be divided into 14 basic lithofacies types including various conglomerate, sandstone, siltstone, and mudstone facies. Braid deltas form in lacustrine basins and can be distinguished from normal deltas and fan deltas based on their sediment source, particle size, and sedimentary characteristics.
sequence characteristic.pptx
This document summarizes sedimentary features of different types of deltas. It describes:
1) A marine fan delta formed by an alluvial fan or braided river depositing sediment into the sea. Coarse beach ridges can form protected lagoons.
2) Marine deltas are classified based on sediment supply and energy levels that control their morphology.
3) Braid deltas form in narrow lake basins where steep mountain slopes enter the lake, depositing coarse sediments.
channel margin bars or levees.ppt
Deltaic systems are subdivided into subaerial plain, delta front, and prodelta facies associations. River-dominated deltas coarsen upward from offshore mud through distributary and beach sands to fluvial deposits. Deltas form thick accumulations of terrigenous sediment that interfinger with fluvial and marine deposits. Characteristics such as channel bifurcation, splay development, and lobe switching occur as deltas prograde basinward over time.
Degree of bioturbation.ppt
The document discusses sediment samples that show:
1) Intensely bioturbated mudstone with a high diversity of burrows including Phycosiphon, Teichichnus, Planolites, Chondrites, and Rhizocorallium.
2) Cross-bedded sediments with clay draped foresets, bidirectional flow, and thick bottomsets that are flaser bedded with variable bioturbation and burrows including Planolites, Macaronichnus, Ophiomorpha, and Thalassinoides, indicating a tidal channel environment.
3) Bioturbated mudstone and laminated mudstone that is sparsely or intensely bioturbated with
Large-scale ripples.pptx
This document discusses the use of sedimentary structures and flow regimes to interpret ancient sedimentary environments. It describes different types of sedimentary structures formed under lower and upper flow regimes by unidirectional and reversing currents. Point bar models are shown to predict structure types from depth-velocity-grain size conditions. The Bouma sequence is interpreted to record a decreasing flow velocity in a turbidity current. Wave-formed structures are related to shoreline processes under different wave conditions. Together, these flow-regime concepts allow detailed reconstruction of depositional processes and paleoenvironmental conditions.
fluvial point-bar depo-sits.pptx
This document discusses the use of flow regime concepts and sedimentary structures to interpret ancient sedimentary environments. It provides examples of how different bedforms relate to flow conditions and produce distinct sedimentary structures. Megaripples produce planar cross-bedding while 3D dunes produce trough cross-bedding. Bouma sequences represent a succession of structures deposited from turbidity currents as flow velocities decrease upwards. Wave structures also relate to flow regime, ranging from ripples to planar beds as energy increases shoreward. These relationships allow ancient strata to be interpreted in terms of processes like river channel migration or turbidity currents.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdf
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
Keywords
Signal to Noise Ratio (SNR), Bit Error Rate (BER), mm-Wave, MIMO, NOMA, deep learning, optimization.
