Summary We present an advanced petrophysical evaluation of a gas-condensate alluvial/fan-delta reservoir case study located in the southwestern Pannonian Basin. We emphasized the petrophysical evaluation on extensive analysis of lithofacies, fracture characterization, paleo-transport, permeability prediction, and rock typing. This evaluation is carried out using integrated subsurface data from image logs, conventional quad-combo logs, and core data, as well as well-test data and machine learning implementation. In addition to the conventional petrophysics interpretation, we identified fracture corridors as potential productive zones through image logs and generated fracture facies for predicting permeability along the fractured zone. In wells with no image log available, fracture facies was estimated based on self-organizing map (SOM) method. Meanwhile, lithofacies were processed using clustering method based on k-Nearest Neighbors. This study provides a method to generate reservoir rock typing and estimate permeability for both matrix and fractured pore systems by considering fractured corridor and matrix lithofacies interpreted from image logs. Also, we offer an alternative approach to predicting fracture corridors in the absence of image logs that consists of implementing the self-organizing map (SOM) method, which helps to define effective flowing thickness or a potential productive zone. Furthermore, paleotransport analysis improved the quality of the sedimentological study.

In propagation of plum by hardwood cuttings, the success of rooting is affected by several factors. Many authors deal with the timing of cutting collections, others investigate the optimal extent of hormonal stimulation. However, there is no data, as yet, about the coherence between these two factors. The aim of this experiment was to find the most advantageous condition s, with regards to both timing and IBA doses, for rentable propagation of the examined varieties. Five varieties were studied: 'INRA Marianna GF 8- 1', 'Myrobalan B', 'MY-KL-A', 'INRA Saint Julien GF 655/2' and 'Feher besztercei'. Cuttings were collected on seven occasions, during late autumn and winter, and were treated with IBA solutions of different concentrations. The optimal dose of IBA was found to be dependent both on the variety and the actual date of cutting collection . Results are reported, along with suggestions for optimal doses and collection periods.

Abstract The paper describes the findings from an implementation project of process safety management (PSM) in the MOL Group based in Hungary. The findings focus on some items that make process safety management successful, sustainable and robust in an organisation. The insights from the implementation are examined: Introduction. Why the implementation is so important - and difficult.Creating access and flow of knowledge. The PSM Network - utilising the collective knowledge of technical experts in the company to improve the data made available during decision making.Focussing implementation effort on critical management systems. The PSM element champions – driving ownership into the operational leadership through systematic action and visible responsibility in key areas.An external conscience and stimulation. A positive improvement focussed 2nd party audit process. Pushing the organisation to take a step back and to understand the effectiveness of implementation of systems, then, critically examine the current action plan for opportunities to refocus effort.Creating the effective balance of action to maintain long term improvement Leadership review, visibility and tolerance of defects - changing the view of leadership from "a valid initiative" to "an essential value".
