Research ArticleOpen accessPhrase in the titleEvaluation of Aquifer Characteristics in Echi, Delta State, Nigeria Using Well Logging and Pumping Test MethodOchuko AnomohanranThis study was carried out to evaluate the aquifer characteristics of groundwater at Echi, Delta State, Nigeria. This was carried out by conducting electrical resistivity and spontaneous potential loggings in a drilled well at the study location. Pumping test using a one kilowatt pumping machine was carried out in the well. The logs were interpreted while the record of the … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,950 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleNumerical Modeling of Periodic Pumping Tests in Wells Penetrating a Heterogeneous AquiferPeter A. Fokker, Joerg Renner, Francesca VergaThis study investigated how to utilize multiple frequency components of pressure data from periodic pulse tests to estimate the intra-well permeability and compressibility distribution and also the presence of heterogeneities in a real field case. Periodic well testing is a technique in which injection or production pulses of a fluid are applied to a well in a periodic fashion. One … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 13 Jan 2013 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAUTOMATIC GLUCOSE INSULIN REGULATION SYSTEM-COMPARISON OF EMBEDDED CONTROL DESIGN AND HARR WAVELET METHOD FOR TYPE-1 DIABETESR. Arangasamy, J. Sundararajan, Ila Vennila, G. ShankarThis article is aimed to inject insulin for type 1 diabetes using pumping the insulin with respect to meal disturbance. We have used the embedded linear parameter varying methodology controller and the final results were compared with the Harr wavelet mathematical values. In this article, there are three things we need to focus. First is the sensor values which is … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 11 Jan 2014 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the keywordsESTIMATION OF AQUIFER PARAMETERS IN ERHO, NIGERIA USING THE COOPER-JACOB EVALUATION METHODOchuko Anomohanran, Ruth E. Iserhien-EmekemeThe aim of this study was to determine the aquifer parameters in Erho, Nigeria. This was carried out by drilling three test wells and three observation wells in the study location. Water was pumped from the test wells at a constant rate while the drawdown in the observation wells was determined as a function of time. The data obtained were … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractReclamation of Irrigated Lands and Improvement of the Groundwater Regime Under Vertical Drainage OperationBalzhan Amanbayeva, Raushan Dzhaisambekova, Alexander Basmanov et al.The aim of the study was to identify patterns of seasonal groundwater-level fluctuations and assess the effectiveness of vertical drainage in regulating the reclamation regime of saline lands in Kazakhstan. The methods included monitoring-well observations, calculation of seasonal amplitudes, Student’s t-test, the Mann-Whitney U test, and Pearson correlation analysis. Before the growing season, groundwater occurred at a depth of 1.5-1.7 … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 608 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Properties of a Dispersant Used for Extracting Oil with High Gas-Oil RatioVladimir Verbitsky, Aleksey Dengaev, Oleg Zubkov, Dmitry KoshkinThe article presents the bench test results for a dispersant manufactured by Izhnefteplast Company, which specializes in batch production of unique submersible pumping equipment for oil extraction. The submersible equipment is unique in that the working elements of the pumping equipment are made of polymeric materials unlike the conventional concept of pumping machinery for oil production. The relevance of the … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 24 Feb 2016 · 7,293 accessesView PDFCite

Research ArticleOpen accessIn the abstractEvaluation of a Dual-Purpose Chemical Applicator for Paddy FieldsMohammed Shu’aibu Abubakar, Desa Ahmad, Othman Jamarei et al.Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractAluminum Powder and Zwitrionic Surfactants as Drag Reducing Agents in Pipe LinesHayder A. Abdul Bari, Rosli Bin Mohd Yunus, Tania Suhail HadiProblem statement: One of the most power consuming sector in the industry is the liquid transportation through pipelines due to the turbulent mode the liquids are transported with. Drag reducing agents were used as a solution for the pumping power losses in pipelines. One of the inportant drag reducing agents suggested to improve the flow in pipelines are the suspended … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,295 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of the Cuttings Cleaning During the Drilling OperationHussain H. Al-Kayiem, Nadia Mohd Zaki, Muhamad Z. Asyraf, Mahir Elya ElfeelProblem statement: Oil well cleaning is the ability of a drilling fluid to suspend and transport drilled cuttings from the down hole (bit face) to the surface. The cleaning performance was affected by many factors such as fluid viscosity, annular flow velocity, angle of inclination and drill cuttings size and shape and. Approach: Navier-Stoke equations, the continuity equation and the … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,249 accessesView PDFCite
