This study deals with the severe uncertainty of using real time mud logging data in the Niger Delta on the operational reliability of the data as an instrument of formation assessment and drilling security. It employed a comparative evaluation of the efficiency of mud logging versus wireline logging and fluid sampling data of the OSA oilfield. A direct comparative methodology was used to compare the data of gas chromatographic and drilling exponent using mud logs together with the petrophysical properties of the wires and the direct results of the fluid sample. The.......

In today's mass retail environment, competitiveness depends on analytical capabilities to manage operating margins. This research addresses the critical situation of Supertiendas y Droguerías Olímpica S.A., an organization that experienced a 63.13% decline in net profits in 2024. The study proposes the transition from a conventional business model to a margin optimization system using prescriptive analytics and data mining. Methodologically, a mixed research approach with a descriptive-correlational scope is adopted. The initial phase consists of a technical-financial diagnosis supported by internal and external factor evaluation matrices (MEFI-MEFE), together with a causality analysis.......

This study examines the subsurface hydrogeological conditions of Bakana in the Niger Delta region, focusing on the impact of hydrocarbon contamination from illegal artisanal refining (kpofire) on groundwater quality and aquifer vulnerability. Electrical Resistivity Tomography (ERT) was employed to map the spatial distribution of conductive zones and assess contaminant migration pathways. The resistivity tomogram revealed a shallow low-resistivity zone associated with hydrocarbon-contaminated fluids, which originated from surface illegal refining activities. Over time, the contaminant plume migrated.......
