Application of Gel for Water Shutoff: A Case Study of Kelebija Oil Field
This paper focuses on the results of water shutoff operations using DSGA polymer gel in the Kelebija oil field. The methodology of candidate wells selection and the manner of performing the operation will also be included. The Kelebija oil field is characterized by a complex reservoir system with heterogeneous layers of different permeability and dual porosity, which led to the early breakthrough of water. For the last 25 years, average water cut was above 90%.

Seasonal Variations of the Zapadna Morava River Water Quality
The water samples collected from four localities of the middle course of the Zapadna Morava River during 2020 were analyzed via the selected physicochemical parameters with the aim to estimate the quality of surface water. According to the results of selected physico-chemical parameters (pH, conductivity, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand), analyzed surface water show a good chemical status, while the values of nutrient content (nitrate, nitrite, ammonium ion, total phosphorus) indicated the poor chemical status especially ...Nebojša Đ.

Потреба за израдом биланса и оценом расположивих резерви подземних вода Републике Србије
Природне карактеристике Србије, просторна дистрибуција ресурса водe и њихових корисника, као и међусобна интеракција коришћења, заштите вода, као и заштите од вода, условиле су да се подземне воде на читавој територији морају посматрати интегрално, јединствено, комплексно и рационално. Међутим, тренутно је у Републици Србији могуће дефинисати само одлике појединих издани и/или изворишта услед непостојања довољних података за свеобухватну анализу стања ресурса.

Uticaj voda Dunava na formiranje kvaliteta podzemnih voda u zoni Apatina
Područje Apatina u proteklom periodu često je pominjano u razvojnim vodoprivrednim strategijama kao potencijalno perspektivna lokacija za izgradnju izvorišta duž obale Dunava, koje bi moglo da ima regionalni značaj. Ovim rešenjem trebao bi se prevazići problem lošeg kvaliteta vode za piće na celom području severne Bačke, tako što bi se kvalitet podzemne vode poboljšao zahvatanjem infiltriranih rečnih voda u priobalju Dunava.

A contribution to the understanding of the discharge dynamics and water balance of the karst spring Gornji Dušnik (Suva Planina)
A sufficiently long time-series of daily discharges is needed to assess the discharge dynamics and calculate the water balance equation parameters of a spring (river source). The paper assumes that a catchment is gauged if a time-series of observations of at least 30 years is available, which is a rare case in Serbia. One-year monitoring is often set up to verify the reserves of a water source or spring intended for capture. Monitoring ceases after the final report is ...Aleksandar Tanasković, Vesna Ristić Vakanjac, Dušan Polomčić, Jelena Ratković.
