Item type:Article, Access status: Open Access , Selected aspects of drilling waste management in Poland(2015) Jamrozik, Aleksandra; Ziaja, Jan; Gonet, Andrzej; Fijał, JerzyOne of the main problems related to environmental protection in the search for hydrocarbon deposits are drilling waste. In these article the authors presented their research results on the toxicity of drilling muds and suggested the possibility of their utilization. Research material represents drilling waste collected during prospecting for both conventional and unconventional deposits of oil and gas in the Polish Lowlands, Pomerania, the Carpathians and the Carpathian Foredeep.Item type:Article, Access status: Open Access , Characterization, properties and microstructure of spent drilling mud from the point of view of environmental protection(2015) Fijał, Jerzy; Gonet, Andrzej; Jamrozik, AleksandraThis investigations were carried out on different spent water-based muds, collected in drillings in various parts of Poland. The combined study methods included structural and phase investigations (X-ray diffractometry, infrared FTIR spectroscopy, scanning electron microscopy) and instrumental chemical determinations. The results characterize mineral and phase composition of the samples, their microstructure and chemical composition. The authors focused on the specific nature of polymer-clay complexes, which in drilling mud systems have the form of delaminated or exfoliated organic-clay polymer nanocomposites that control properties of such waste materials. Detailed recognition of properties chemistry, mineral and phase composition, microstructure of spent drilling muds have a fundamental meaning for studies on the management of these materials in the natural environmental.Item type:Book Chapter, Access status: Open Access , Mikro- i nanomateriały w technologii płuczek wiertniczych na bazie olejowej, stosowanych do wiercenia otworów w warunkach wysokiego ciśnienia i wysokiej temperatury (HPHT)(Wydawnictwa AGH, 2024) Jamrozik, Aleksandra; Szczygieł, AndrzejOil-based drilling fluids are primarily used in challenging geological and reservoir conditions, such as high temperatures, high pressures, reactive rock formations, or the influx of mineralized formation water. This publication presents the results of laboratory tests on the rheological properties and stability of oil-based drilling fluid, with micronized barite as the weightening material. To enhance the stability of these drilling fluids, an organophilic nanomaterial – amino-attapulgite, was used. The research demonstrated that the combination of micronized barite and amino-attapulgite in oil-based fluids allows for the modification of their properties across a wide range of densities and low rheological values. The results showed that incorporating organophilic attapulgite and using micronized barite as the weightening agent reduces sedimentation conditions and improving stability drilling fluids.Item type:Article, Access status: Open Access , Utilisation of drilling waste muds from drilling waste dump(2015) Kotwica, Łukasz; Wons, Wojciech; Malata, Grzegorz; Murzyn, Paweł; Jamrozik, Aleksandra; Gonet, AndrzejDynamically developing drilling industry is connected with some environmental impact. Considerable amounts of contaminated drilling waste is produced, regardless the applied prevention measures. The generated drilling waste is diversified both chemically and physico-mechanical. These properties make utilization or managing of drilling waste difficult. In article presented results laboratory research stabilization of drilling waste mud from Polish commercial drilling waste dump. Samples were taken from an old lot which is not currently under operation and was provided to be subjected to reclamation. Investigated waste drilling mud stored in waste dump contains high amounts of unbound ions, which can be leached out of the sample. It cause the method of utilization to fulfill two goals: first it should allow to solidify the material in order to obtain material easy to transport and process and second the method should allow to decrease the amount of ions which can be leached out of the final material.Item type:Article, Access status: Open Access , Analysis of waste mud stability(2014) Jamrozik, Aleksandra; Gonet, Andrzej; Fijał, Jerzy; Terpiłowski, Konrad; Czekaj, LucynaDrilling fluids play a number of functions, e.g. they remove cuttings, lubricate the drill bits, maintain stability of the hole and prevent the inflow-outflow of fluids between well and the shales. For this reason, they are made of complex polymeric-mineral microcomposites of differentiated chemical and mineralogical-phase content with varying share of colloidal phase in dispersed solid phase in water, i.e. water-based muds (WBM) or oil environment, i.e oil-based muds (OBM). The major factor providing stability of the presented systems is the high participation of clayey minerals (smectite group), long-chain polymers and chemicals stabilizing dispersions. The results of analyses of concentrated dispersions of waste muds from a few regions in Poland are presented int he paper. These are plastic-viscous dispersions of rheological parameters described most frequently by the Herschel-Bulkley model, the flow of which is connected with deformations of internal structures in the analyzed systems taking place in a function of temperature. There are also presented measurement results of light transmission and backscattering in the analyzed range of temperatures, i.e. 20 to 60°C with the use of Turbiscan Lab., Formulaction. The stability indicator is the turbiscan stability index (TSI).Item type:Article, Access status: Open Access , An application of organic nanosilica to cement slurries based on Portland cement(2015) Jamrozik, Aleksandra; Stryczek, Stanisław; Wiśniowski, Rafał; Gonet, Andrzej; Wójcik, RafałMore and more attention is paid nowadays to the quality and durability of the applied cement slurries. Apart from the appropriate rheological, technological and strength parameters, the slurry should be resistant to the strongly mineralized reservoir waters. Appropriate phase composition of cement slurries, especially high CSH content is responsible for the change of pore structure in the cement slurry; the number of fine gel pores which are not available for the fluid increases and the number of capillary pores responsible for the transport of corrosive factors inside the cement slurry decreases. The use of nanosilica as an additive improving the properties of cement slurries has recently gained popularity. Bearing in mind these properties of nSiO2, there were conducted laboratory experiments on the use of organic nanosilica for cement slurries based on Portland cement CEM I 52.5 R.Item type:Book, Access status: Open Access , Wybrane aspekty zarządzania płuczkami i odpadami wiertniczymi w kontekście zrównoważonego rozwoju oraz gospodarki o obiegu zamkniętym(Wydawnictwa AGH, 2025) Jamrozik, AleksandraItem type:Article, Access status: Open Access , Problems related to oil and gas mining waste deposition in view of legal regulations(2012) Dubiel, Stanisław; Jamrozik, Aleksandra; Matyasik, Agata; Ziaja, JanThe legal regulations on mining waste have been reviewed in the paper. The most important problems related with exploitation waste management in oil and natural gas production have been analyzed. Industrial examples of waste neutralization have been presented.Item type:Article, Access status: Open Access , An analysis of fluids after hydraulic fracturing in the aspect of their further use or neutralization(2013) Jamrozik, Aleksandra; Gonet, Andrzej; Czekaj, LucynaToday’s ecological policy focuses on preventing anthropogenic environmental hazards. A large share of activities are oriented to the precise recognition of hazards and use of solutions thanks to which the negative environmental effects of mining activity can be considerably reduced. Issues related to the recovery of water after hydraulic fracturing with emphasis on the possible utilization and management of fluids after hydraulic fracturing in Polish conditions are discussed in view of the respective law.Item type:Article, Access status: Open Access , Characteristics of oil based muds and influence on the environment(2016) Jamrozik, Aleksandra; Protasova, Evgenia; Gonet, Andrzej; Bilstad, Torleiv; Żurek, RomanOil based muds (OBM) are highly important in well drilling. Water based muds (WBM) and synthetic based muds are not providing sufficient qualities in fulfilling all of the functions of OBM. OBMs ensure more efficient drilling but also disadvantages such as higher initial cost, more stringent pollution controls and reduced effectiveness of some logging tools. Expenses for mud are reaching 10–15% of total well cost. However, high costs are still low compared to expenses for corrective measures in the case of using mud with poor properties, which could lead to drilling disruption as well as excessive time and cost. OBM and cuttings are saturated with toxic compounds and if discharging to sea poses ecological threats. Perhaps the most hazardous oil component for aquatic organisms are low-boiling aromatics, which consist of benzenes and naphthalenes both soluble in water. Additionally, the higher-boiling aromatic fractions are of high environmental interest due to their persistence in sediments, leading to enzyme induction, cellular dysfunctions, genetic alterations, and chronic effects on organisms. There is a difference in volume of generated waste between using water- and oil-based muds. WBM produces 7,000–13,000 bbl of waste per well. Depending on well depth and diameter 1,400–2,800 bbl are drill cuttings. OBM generates mush less waste as the mud is usually recycled and only drill cuttings with volumes of 2,000–8,000 bbl per well need treatment prior discharge. This paper discusses the hazardous effect of toxic compounds in OBM and evaluates the efficiency of different OBM treatment towards zero discharge.
