Abstract:
One of the recoverable coastal resources that can make a high contribution to the coastal environment and to coastal communities is the seagrass ecosystem. Seagrass is a flowering aquatic plant that has the ability to adapt to live in the marine environment. Seagrass has many functions, such as a nursery ground, a feeding ground and a spawning ground for fish and other biota that have high economic value. Various threats to the sustainability of the seagrass ecosystem in Indonesia continue to increase year after year. Commonly used seagrass transplant methods include the plug, sprig, tie sack

Abstract:
Several specimens of biogenic structures somewhat resembling plug-shaped ichnofossils have been collected in two muddy deposits, Sicilian (Early Pleistocene) in age (Bossio et al., 1987), outcropping near Lecce, southern Apulia, Italy. One sequence is exposed in an unused quarry located at the eastern side of the Cutrofiano–Supersano road, 31 km post; the other one is in an active quarry, southwest of Lecce, near the village of San Pietro in Lama (Figure 1). The diagnostic features of the traces differ from those of the five ichnogenera recognized by Pemberton et al. (1988) for plug-shaped ich

Abstract:
In this paper, we investigate the dynamics of muddy-seabed motions induced by a surface solitary wave. The muddy seabed is characterized as Bingham-plastic mud. We focus our attention on the situations where the horizontal scale of the wave-induced mud flow is much larger than the vertical scale. The thickness of the mud layer is also assumed to be much smaller than the water depth above. With these simplifications, the dynamic pressure in the mud column remains a constant and the vertical displacement of the water–mud interface is negligible.

In the experiments a clear silicone fluid was used as the viscous mud and particle image velocimetry was employed to measure the velocity field inside the viscous mud.

Abstract:
In carbonate reservoirs, permeability prediction is often difficult due to the influence of various geological variables that control fluid flow. Many attempts have been made to estimate permeability from porosity by using theoretical and empirical equations. The suggested permeability models have been questionable in carbonates due to inherent heterogeneity and complex pore systems. The main objective of this paper is to provide a workflow to improve the use of existing models (e.g., Kozeny, Lucia, and Winland) to predict permeability in carbonate reservoirs.

Abstract:
Summary Several areas of the geosciences have benefitted from the application of the new mathematics of "fuzzy logic."1,2 The oil industry now routinely uses new interpretation techniques, based on fuzzy logic, to predict permeability and litho-facies in uncored wells. Litho-facies and permeability prediction have presented a challenge to formation evaluation due to the lack of tools that measure them directly. The method described can be used as a simple tool for confirming known correlations or as a powerful predictor in uncored wells. Fuzzy logic is simply an application of recognized stati

AbstractBubbles grow and burrows extend through cohesive, muddy marine sediments by fracture. In contrast, sands are non-cohesive, granular materials. Natural sediments comprised of heterogeneous mixtures of muds and sands are common in coastal areas and provide important habitat for infaunal animals. To explore the transition from cohesive to non-cohesive mechanical behavior of natural sediments, we modified a probe designed for measuring fracture toughness (KIc). The helical probe is rotated and translated into sediment to grip a plug of sediment, then translated upward to break off the plug

Highly efficient sediment gravity flows can bypass mid fan channels and lobes and deposit significant volumes of sand, mud and particulate organic matter in outer fan and basin plain settings.

As part of a broader progradational succession, the upward transition from muddy basin floor to sandy fan preserves the stacked deposits of settings present prior to and outboard of mid-fan channels and lobes.

Abstract:
The study of the interaction processes between polymer-based drilling fluids and clay rocks is essential. Careful selection of drilling fluid composition will allow you to avoid such complications during drilling as the bridge over, clogging of the bottom-hole zone with cuttings, reduction of the mechanical drilling speed, differential wall sticking, a fluid wash of the wellbore walls and core plugs, and drilling fluid losses. Various salts of alkali and alkaline earth metals are often used as clay swelling inhibitors, which can cause changes in the rheological properties of the drilling fluid

Vitamin B12 (cobalamin, CBL) is important in the effective metabolism of homocysteine and thus defects of CBL absorption, transport, and intracellular transport are also discussed.

Abstract Primary drainage capillary pressure data are essential input for static modelling of hydrocarbon reservoirs, estimate both oil and gas volumes in place and model saturation distribution. The behavior of the primary drainage curve is controlled by the pore throat size distribution, where a much wider pore throat size distribution is observed for heterogenous reservoirs. The objective of this paper is to determine capillary pressure modeling parameters for a wide range of geological textures of carbonate reservoirs covering different porosity and permeability ranges.
