Opis:
The article presents selected technical issues relating to drilling performed by a drillship, one type of drilling rigs. Basic problems encountered in the main function of such rigs − drilling a well − are failures of mud pumps. The authors investigate these pumps in operational conditions, aiming at development of a system for monitoring the technical condition of these pumps. Work on a diagnostic system is in progress that will permit to predict the condition of mud pump valves well in advance.

Opis:
Recently, studies contributing to development of complete mud system, which would enable drilling the borehole of arbitrary length (including directional and horizontal boreholes) without necessity of mud changing are conducted at the Faculty of Drilling, Oil and Gas AGH-UST Krakow. The article describes technological parameters of developed base mud (BFP) which constitutes ground of developed system. BFP mud will be applied as a structure-forming agent allowing suspension of other components in the drilling mud. BFP mud is characterized by low values of plastic viscosity in wide range of concentrations as well as enhanced strength parameters (Yield Point, Geles). Its parameters are easy to adjust to different geological conditions. The mud is resistant to mono- and divalentions and to increased temperature. Due to those facts, abovementioned mud can find application in the drilling industry.
Opisano parametry technologiczne opracowanej na WWNiG AGH w Krakowie płuczki bazowej (BFP), która stanowi podstawę kompletnego systemu płuczkowego umożliwiającego odwiercenie otworu o dowolnej długości (w tym również otworów kierunkowych i horyzontalnych) bez konieczności wymiany płuczki. Płuczka BFP jest przeznaczona do zastosowania jako środek strukturotwórczy, pozwalający na zawieszenie w nim pozostałych surowców płuczkowych. Płuczka BFP charakteryzuje się niewielkimi wartościami lepkości plastycznej, w dużym zakresie stężeń, i polepszonymi właściwościami wytrzymałościowymi (Yield Point, Geles), a parametry te można łatwo regulować. Jest odporna na zasolenie jonami jedno- i dwuwartościowymi oraz na podwyższoną temperaturę. Może znaleźć zastosowanie w przemyśle wiertniczym.

Opis:
Spent of water based mud (WBM) were tested in this study. Bioassays were done on spent WBM, brine after filtration and solid phase (SP) after filtration on the press. As test organisms, green algae Kirchneriella obesa and Botrydium granulatum were used, along with the cladoceran Simocephalus vetulus and the plant Lepidium sativum. Electrolytic conductivity was between 6.43 and 240 mS/cm. The liquid phase was toxic for K. obesa in the range of dilutions between 0.21 and 0.019, considered as LC50. The parameter LC50 in the category of dilutions was 0.125 to 0.0078 SPP for S. vetulus, 0.25 to 0.094 SPP for green alga Botrydium granulatum when diluted by brown soil and 0.56 to 0.039 SPP for Lepidium sativum. Maximum quantum efficiency (QY) of plants’ photosystem II (PS II), growing on mixtures of drilling fluids with soil, did not depend on the kind of drilling fluid, whereas minimal fluorescence (F0) did. Rinsing the salt out of drilling fluids in a 1:1 proportion was effective only for bentonite mud in the test with L. sativum.

This paper presents laboratory researches on KAN-001 cationic polymer application dedicated for drilling fluids used in drilling through sensitive shale formation and also the formulation of a new mud system for drilling in clayish rocks. Laboratory researches showed the great utility of KAN-001 polymer, synthesized in AGH-UST, for its application in special drilling fluids for shale and clay rocks. A new mud system – Mud-17 – with an addition of KAN-001 polymer, is distinguished by good technological parameters. It is resistant against univalent and divalent salts contamination. Therefore, a new mud system can be salted up to the saturation. Mud-17 is also resistant against high temperature, so it can be used in deep wells.

A major source of valued water are groundwater deposits. Therefore, constantly growing water demand requires greater focus on the subject of hydrogeological drilling. The primary requirements for groundwater drilling are: protection of important aquifers as well as formations being drilled and further easy removal of the mud residues during well development. Both aspects are connected to mud ingredients and additives selection. This necessitates an improvement of drilling fluid formula for most effective borehole drilling and successive exploitation. This article concentrates on the drilling fluid for hydrogeological drilling. In order to validate the practical utility of developed mud, laboratory research was conducted. An analyses of the outcomes expose the mud improving drilling process and fulfilling above mentioned requirements

'Faster, deeper, cheaper' -it is not just a slogan, it is a motto of every oil company. The first application of rotary--percussion drilling method in drilling oil wells took place in early 60's of the XX century in the United States. Unfortunately, in Poland did not apply. First of all, the main advantage is the inereased rate of penetration, in comparison with standard rotary drilling, and consequently - lower wellbore costs. The purpose of present paper is to discuss the historical background of application of rotary-percussion drilling method, technological changes that have oceurred over the years, and to show the potential of this drilling method, using modern technology, in comparison with standard rotary method.

Opis:
In this study, the adsorption behavior of natural and activated zeolites with respect to Cd2+, Cr3+, Pb2+and Zn2+, was studied in order to consider theirabilityto remove hazardousmetals fromdrilling mud. The batch method was employed, using initial metal concentrations in solution in the range of0.1 to 2.5 mg/dm3. It was determined that independently of the concentration, the adsorption ratios of zeolite towardsmetal cations match the Langmuir and Freundlich isotherms. The results of the research on the reduction of concentration of hazardousmetals from drilling mud wastewater by means of natural and activated zeoliteswere presented in the further part of this work. Natural and activated zeolites were introduced in portions (from 0.2to 10 g) to 100 cm3of wastewater; then, the content of metalions was determined using an inductively coupled plasma spectrometer. The experimental data showed that the applicationof activated zeolite enabled the removal rate of Cr3+, Pb2+, Zn2+and Cd2+close to 93%, 45%, 56% and 84%, respectively. In the case of the natural zeolite, the degree of hazardousmetals removal was lower by only a few percent, but still high enough to beinteresting from the practical point of view. Satisfactory effects of hazardousmetal ionsremoval from drilling muds were achieved using 2 to 5 g of zeolite. The obtained results proved that the natural zeolite constitutes an important material for efficient removal of hazardousmetalionsfrom drilling mud wastewater.

The paper is dedicated to the issue of assessment of alumina (red mud) production waste on natural water. The growth of the number of aluminium-producing facilities leads to the expansion of exclusion areas to store the production waste – sludge dumps. A considerable part of research on red mud utilisation is focused on its use in the iron-and-steel industry. Furthermore, the technologies of red mud usage in the construction industry gain substantial significance for land reclamation, isolation of polluted industrial and agricultural lands as well as the effluent and industrial emissions treatment.

Opis:
Rheological properties of mud should assure high rate of penetration and supply maximal hydraulic power to the hole bottom. From this point of view drilling mud should have as little density and viscosity as possible and also minimal solid phase fraction. By the reason of the hole depth and geological conditions in the region it often occurs that maintenance of low density is impossible and drilling mud have to be treated with weighting materials. The process may cause change of mud rheological parameters and cause decrease of penetration rate. In case of weighted mud there is also a problem consisting in sedimentation of weighting material. During these project realization there was developed recipe of new mud for well completion with new PT-23 polymer. The next step was testing of possibilities of weighting the mud with different weighting materials: barite with grain size lower than 75 um, barite with grain size lower than 25 um, commercial barite, hematite, bridging agent M-25. Barite with grain size lower than 75 um and barite with grain size lower than 25 um were conditioned in water, then wet separated into fractions.

Opis:
Drilling 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 inthe 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).

Opis:
Natural radioactive elements such as uranium and thorium restrict the use of red mud as building materials or additives, and may cause environmental problems. The distribution features of U and Th in red mud was studied from micro and macro analysis, using EPMA, LA-ICP-MS, and methods of mineralogy and beneficiation. Based on the micro-area scanning analysis, main chemical compositions in red mud, such as Ca, Al, Si, Na, and K are dispersive while Fe and Ti mainly tend to concentrate in granular phases. Based on the in-situ analysis, the distribution of main elements and most trace elements in micro-zone of red mud was homogeneous. In micro-zone area, the variation tendency of thorium content was similar with Y in red mud samples. By means of the methods of mineralogy and beneficiation, red mud samples were separated into different fractions. U and Th tend to be enriched in the low density fraction of the red mud. Th presented a high concentration in the finest particle size fractions of the red mud. Neither U or Th was regularly distributed in various magnetic red mud fractions. Thorium fingerprint peaks were determined in perovskite by EDX under TEM, which is proposed to be one of the radioactivity sources in Bayer red mud.
