Abstract: The constituent budget of Njaba River at Okwudor was undertaken to understand the loading rate of constituents over a period of time (2011-2019). Water samples were obtained at equal distances of 2 km along the stretch of the River. The samples were obtained with the aid of sterilized 1.5 plastic bottle; the sample bottles were corked under water immediately after collection so as to prevent oxidation of the constituents. The water samples obtained from Okwudor was used to probe some physiochemical parameters and constituent budget of Njaba River over a period of eight years (2011 – 2019). The result indicates the pH of the River with values of 6.40 in 2011 and 6.44.......

Abstract: The Old Brahmaputra is a tributary of the Brahmaputra River that finally falls into the mighty Meghna River at Bhairab Bazar, Bangladesh. The morphology of this river indicates that it is a meandering river. The sedimentary sequences are composed of alternate beds sands and clay. The coarser sand beds were deposited at high energy condition of the river. The present study reveals that Fm, Sh and Sp facies constitute the lithological succession of the study area. The massive clays with peds were formed in the backswamp when the depositional basin became shallow and lost its energy. Textural studies of the sand samples exposed along the left bank of the Old Brahmaputra near Mymensingh town shows that the graphic mean sizes vary from 3.41 to 3.50ɸ, very fine sand. The sediments are well sorted that indicates the marine transgression of the Bengal Basin at the time of deposition. The sands are strongly coarsely skewed. The scatter plots of the deposits decipher that they deposited either in river or beach environments.....

Abstract: Elastic Geomechanical properties are key elemental properties that must be adequately predicted for wellbore stability and effective hydraulic fracturing to be assured. Understanding these properties is key for planning drilling, production and reservoir management. This research analyses elasticGeomechanical properties predicted by seismic and well log data in "AJAH" Field offshore Niger Delta using Artificial Neural Network. Analysis of well logs (5 wells) shows that the Poisson's ratio (V), Shear modulus (G), Young's modulus (E), Bulk modulus (K), Compressibility (β) and Unconfined compressional strength (UCS) range from 0.11- 0.47, 0.15 – 8.5˟ 1010pa, 0.15 –14.3 ˟y....

Abstract: The development of high temperature geothermal systems in Kenya is partly due to the occurrence of shallow magma bodies under volcanoes in the axis of the rift. Drilling of geothermal wells presents a critical development activity of a geothermal project. However, drilling activityfaces numerous challenges which negatively affect drilling rates. The drilling costs are increased since drilling operations are run on tight schedules and any delays come at a high cost. Some of the most common drilling problems can be attributed to lithology and stratigraphy of the formations. This research assessed the effect of lithological characteristics and structural attributes on the drilling rate at Olkaria geothermal field. The study investigated the joint effect of lithostratigraphy, geological structures and hydrothermal alterations on the drilling rate usingwells OW 724B and OW 45V as case study. These wells experienced drilling challenges caused by severe formation problems leading to high non-productive.....

Abstract: Deterministic hydrocarbon volume estimation is applied to predict hydrocarbon volume initially in place in Fuba Field Onshore Niger Delta, Nigeria using Well-log and seismic data. Well-to-seismic-ties, faults and horizon mapping, time surface generation, velocity modelling and depth conversion were carried out using Petrel software while uncertainty analysis was carried out using Crystal Ball Monte Carlo simulation software. The reserves estimated using the deterministic approach were 18.52MMSTB,13.59MMSTB, 9.40MMSTB, for the high, base and low cases of reservoir A while that of reservoir I was 25.56MMSTB, 14.59MMSTB and 7.63MMSTB for the high, base and low cases showing that there is a significant difference between the high, low and base case volumes......

Abstract: This days land subsidence activities have been increasing rapidly in Malaysia. Land subsidence is now one of the serious threats to the country which is caused by excessive withdrawal of ground water and extraction of ground resources along with the rapid development of infrastructures of cities and urban areas. Ground subsidence is define as the differential sinking of the Earth's surface with respect to terrain that surrounded the surface area. It is due to the extraction of ground resources and presence of voids in the subsurface generated either naturally or by human activities. This study aims to detect and measure the ground movement in SeberangPerai using active remote sensing and geophysical approach. RADAR interferometry (InSAR) is a remote sensing technique which measures the minute changes in ground movement to millimetre scale. Persistent Scatter (PS) and Minimum Spanning Tree (MST) interferometry stacking techniques were applied to Sentinel-1A data.....

Abstract: In this study, the ambient seismic noise cross-correlation technique is applied to estimate the
thickness of the sedimentary column and crustal structureof southern Iraq. Continuous data from three seismic
broadband seismic station were usedto calculatephase velocities of Rayleigh waves using time-frequency
analysis. The observedphase velocities were inverted considering linear iterative inversion procedure and
several 1-D shear wave velocity models in order to obtain thecrustal structureof the study area. The results
show that the sedimentary thickness is around 10km(Vs 1.995-2.485km/sec),the Conrad discontinuity is located
approximately at 22km depth (Vs 3.114-3.428km/sec),and the Moho discontinuity is located around 41km depth
(Vs 3.827-4.708km/sec).
Keywords: Mesopotamian zone of Iraq, the crustal structure of southern Iraq, cross-correlation of ambient noise, Rayleigh wave phase velocities.
