GEOCALCULATOR, AN APPLICATION SOFTWARE FOR THE DETERMINATION OF VOLUME OF SHALE AND FORMATION WATER RESISTIVITY FROM SP LOGS
Benson Akinbode Olisa, Adedamola Bill Folaranmi Abstract: Formation evaluation in hydrocarbon exploration is focused on determining productive reservoirs in wells, if any, and the volume of hydrocarbon in said reservoirs. The volume of hydrocarbon in a reservoir depends on the water saturation, a function of its formation water resistivity. The calculation of formation water resistivity, volume of shale and hydrocarbon saturation from SP logs is dependent on several Petro-physical parameters which require complex calculations using many charts that are time consuming and error prone. This project designs and incorporates the use of a computer software designed to standardize results, reduce margin of error and the time spent on calculating these Petro-physical parameters which is especially valuable when working on data from a large number of reservoirs and wells. A standalone application software was designed for this project in Unity and the results were compared versus standard chart corrected calculations using data from existing literature. The maximum deviation falls within a rounding error at minimum and up to 7.2464% as formation water resistivity increases. The value falls well below 10% and is reasonably in range of values normally observed in the field and from chart calculated data. The calculated data allowed the detection of suspected errors in the published results of existing literature. The software has proven to be a fast technique of estimating formation water resistivity, volume of shale and hydrocarbon saturation and reduces the ambiguity in the use of charts for correcting Petro-physical parameters in well log analysis.
ANALYSIS OF AN UNSUPERVISED CLUSTERING ALGORITHM FOR LITHOFACIES CLASSIFICATION IN RIGA FIELD, NIGER DELTA
Olisa Benson Akinbode and Oluniyi Taiwo Samuel Abstract: The study determined the optimum number of clusters that effectively capture lithological variations in subsurface formations and also emphasizes the application of these clustering algorithms for lithofacies classification. The k-means clustering algorithm was used to uncover hidden patterns in well logs in the Niger Delta RIGA field. This model successfully classified the data into 4 distinct clusters, revealing correlations with depth and gamma ray (GR) measurements. The developed clustering model was able to automatically classify the dataset into useful clusters, these clusters, when matched with depth, generated useful lithologies in the well RIGA-1 and RIGA-2. There are 4 clusters having 3 very visible clusters similar to Continental sands, Marginal marine sandstones and Shale. These mostly tie up with the changes in the logging measurements, decrease in Gamma Ray (GR) from around 4900m to 6100m, 7700 to 7600, 8500 - 9700 aligns with the blue clusters in Well 1 and Well 2.
RESERVOIR DELINIATION USING WELL LOG DATA IN NOLIX OIL FIELD NIGER DELTA
Olisa Benson Akinbode Abstract: The sand in the Nolix oil field is vertically stacked and can be correlated from well to well. Three oil wells were used for the analysis, Nolix-01, Nolix-02 and Nolix-03. Three sand levels, sand 1, sand 2 and sand 3 are established stratigraphically in each well using gamma ray (GR) logs. Sand 1 in Nolix-01 is the shallowest in Nolix well and appear at 6060ft-6140ft (true vertical depth subsea, TDVSS). The thickness is 80ft (24m). Reservoir analysis was carried out with the use of log motif (shape or pattern) of the GR and resistivity curves in combination. The reservoirs identified were point bars and barrier bar sands. In Nolix-03 well, sand 3 range from 7560ft-7860ft (true vertical depth subsea, TDVSS). The thickness is 300ft (109m), the electric log patterns are serrated blocky and blocky.
DESIGN AND DEVELOPMENT OF AN IoT-BASED FACE RECOGNITION SMART ACCESS CONTROL SYSTEM
Nnajiofor George Anayo, Cosmas Kemdirim Agubor, Longinus Sunday Ezema, Amadi Christopher Chidi Abstract: This thesis presents a smart IoT-based face recognition access control system. Initially, users must enter a password. If the password is correct, the door unlocks automatically; if incorrect, the system triggers an alarm, captures images of the user, and sends a security alert with the photos to the rightful owner via the Telegram application. The system captures the intruder face and denies access to unauthorized users if the captured face does not match the stored one. It allows authorized users to enter and exit restricted areas and features real-time image capture and transmission of the intruder photos.
ANTHOCYANINS EXTRACTION FROM CAMOTE TOPS (Ipomoea batatas) LEAVES AS AN ALTERNATIVE pH INDICATOR AND ITS COLOR CHART
CHINEE I. FLORES, KIMBERLY L. GALON, GENEVIEVE M. MANLUNAS, DEXTER P. PALAWAN , CHLERA MEIAH M. TALONDATA, DANAH ROSE ANDREA M. DULANA, HARDY BANKAS Abstract: The role of pH indicator was used in various ways including measuring the pH of farm soil, different household substances and bodies of water. This comparative experimental study was conducted to prove and present an alternative pH indicator that can measure accurate pH level of a substance with distinct color change and wavelength that can be observed with the color chart of alternative pH indicator as the output of this study. In addition, this study considered the role of anthocyanin content of camote tops leaves extract on the absorption of light and in spectrophotometeric analysis and compare its efficacy with Phenol red. Researchers applied two concentration in testing: 300mL of water: 5 grams of camote tops leaves: 180 mL of ethanol; and 400mL of water: 5 grams of camote tops leaves: 240 mL of ethanol in different volume of 3mL, 5mL, and 10mL of camote tops leaves extract. The results indicated that both concentrations compared to Phenol red in terms of pH level and wavelength the two pH indicators showed no significant difference but had a significant difference in terms of color change. The researchers concluded that anthocyanins from camote tops leaves extract can be an alternative pH indicator that shows a wide pH range from 2-11 levels (pink as acid, green as basic to yellow in highly basic). The researchers developed a pH color chart of camote tops leaves extract recommended for measuring pH level of household substances, farm soil, bodies of water, and are readily available science experiments that can benefit farmers, teachers, and students.
From the Perspective of Ecological Literary Criticism: An Analysis of Life of Pi
Xiaoya Lv, Hongya Niu Abstract: Life of Pi is a novel by Yann Malte that was adapted into a film of the same name by director Ang Lee. The work has attracted wide attention with its profound ecological themes. This paper will use the method of ecological literary criticism to explore and analyze this work, and study the changes in the relationship between man and nature involved in it, from the stage of anthropocentrism to the stage of confrontation and contradiction between man and nature, and then to the stage of harmonious coexistence and interdependence between man and nature, which is an ecological whole, and dig ecological value from it. It is beneficial to better view the relationship between man and nature and cultivate the heart of reverence for nature and the way of living in harmony with nature.
A Comparative Study of Stance Markers in Chinese and American Mainstream Media Reports on the Belt and Road Initiative — A Focus on the Belt and Road Forum on International Cooperation
Xiaoya Lv Abstract: As the highest-level international event under the Belt and Road framework, the Belt and Road Forum for International Cooperation plays an important role in promoting the Belt and Road Initiative. How the mainstream media of China and America view about the forum is also very influential in the international community, affecting many aspects. However, previous studies on the Belt and Road Forum for International Cooperation focused on the metaphorical framework, news narrative, national image construction, critical discourse analysis and conceptual metaphor, and so on. The analysis on the stance markers of the forum by Chinese and American media is rare.
