This paper describes the existence and condition of women homeworkers (PPR/Perempuan Pekerja Rumahan) in the Special Region of Yogyakarta (DIY). Based on the data and analysis results show that the conditions of the PPR in the Special Region of Yogyakarta in particular and Indonesia in general have not received their proper rights as workers, as stated in the ILO Convention Number 177 of 1996. This is indicated by the existing laws and regulations in Indonesia, commitments and the support of the regional government has not guaranteed PPR rights. Therefore, through the MAMPU Program, in this case YASANTI strives for rights and protection for PPR is guaranteed social protection and rights as workers, such as other formal or informal workers. The MAMPU program carried out for this purpose is to increase the access of homeworkers to social protection programs and improve the conditions of women homeworkers and eliminate discrimination in the workplace. The program has succeeded in placing PPR as a group of workers who need to get social protection and be treated equally in their rights as workers, like other workers. Makalah ini menjelaskan keberadaan dan kondisi pekerja rumahan perempuan (PPR / Perempuan Pekerja Rumahan) di Daerah Istimewa Yogyakarta (DIY). Berdasarkan data dan hasil analisis menunjukkan bahwa kondisi PPR di Daerah Istimewa Yogyakarta khususnya dan Indonesia pada umumnya belum menerima hak yang layak sebagai pekerja, sebagaimana dinyatakan dalam Konvensi ILO No. 177 tahun 1996. Hal ini ditunjukkan oleh hukum dan peraturan yang ada di Indonesia, komitmen dan dukungan pemerintah daerah belum menjamin hak PPR. Oleh karena itu, melalui Program MAMPU, dalam hal ini YASANTI mengupayakan hak dan perlindungan bagi PPR dijamin perlindungan sosial dan hak-hak sebagai pekerja, seperti pekerja formal atau informal lainnya. Program MAMPU yang dilakukan untuk tujuan ini adalah untuk meningkatkan akses pekerja rumahan ke program perlindungan sosial dan meningkatkan kondisi pekerja rumahan perempuan dan menghilangkan diskriminasi di tempat kerja. Program ini telah berhasil menempatkan PPR sebagai kelompok pekerja yang perlu mendapatkan perlindungan sosial dan diperlakukan sama dalam hak-hak mereka sebagai pekerja, seperti pekerja lainnya.

Published: February 2022

The analysis of field data from casing failure on the fields of the Borislav and Dolinsky oilfield regions has been carried out. It has been found that the most significant negative factors that have a bearing on the preservation of the integrity of the casing strings are the presence of saliniferous rock intervals in the borehole log and not taking into account the possible impact of rock pressure when designing casing strings in these rocks. In saliniferous rocks, under certain conditions, rock pressure can be transferred to the column. To study the thermobaric conditions of the external pressure transfer to the casing from the saliniferous rock, experimental tests have been carried out on the core materials of the rocks of the Vorotyshchensk floor, sampled at different depths of the Oriv-Ulychniansk field. For this purpose, a special laboratory installation was made, which allows to study the stress conditions and rock flowage on exposure to formation temperature and rock pressure. Because it was difficult to directly measure the radial pressure transmitted to the pipe and the temperature inside the chamber during the experiments, the installation was calibrated by pressure and temperature. This made it possible to determine the temperature inside the chamber by the value of the voltage supplied to the heating element, and the value of the radial pressure supplied to the pipe - by the value of the pressure inside the pipe. Based on the results of experimental research, the depen-dences of the lateral earth pressure coefficient of saliniferous rocks on temperature were obtained at various values of normal stresses. It was found that when the temperature rises to 70 ° C and higher, the value of the lateral external pressure on the pipe approaches the vertical component of the pressure. According to the results of the experimental research, the temperature and pressure conditions for accounting for rock pressure were recommended when calculating casing strings for external overpressure in the intervals of occurrence of saliniferous rocks of the Carpathian fields.
Improving the rheological properties of alkaline-activated geopolymers using water-free fluids
Authors: Aliev A. A. 
Published: February 2022

Geopolymer systems are quite successfully used in such operations as industrial and civil construction, production of fire - resistant concrete, isolation and disposal of radioactive waste, etc. The oil and gas industry was no exception. They are one of the most promising alternatives to Portland cement in insulation operations. They allow achieving sufficiently high performances of well construction strength, corrosion resistance, and in some compositions these parameters significantly exceed those of Portland cement. In recent years, a significant amount of research has been carried out aimed at the development of geo polymer compositions for cementing oil and gas wells, which showed that these systems have strength characteristics comparable to Portland cement, low permeability, resistance to drilling mud and reservoir conditions, and the ability to self-repair. However, despite all the advantages of Geo polymer systems, their most significant disadvantage is poor regulation of rheological properties. Geo polymers (GP) with low ash content do not provide the proper rheological characteristics for the use in insulation operations. Low values of pumpability of solutions are still a serious restriction for wide practical implementation. The use of geopolymer solutions with the correct selection of the compositional composition capable of demonstrating significant improvements in strength and rheological parameters as a result of mixing with anhydrous drilling fluids is a very promising solution to this problem. The paper presents the results of research on the additives of non-aqueous fluids such as oil- based and synthetic-based drilling fluids and inverted emulsion drilling fluids on rheology of geo polymers. The obtained results allow stating that the rheological parameters of geo polymer compositions improve up to comparable values with Portland cement, which considerably extends the range of application of these solutions to use in operations of primary, squeeze cementing and well workover.
