Abstract:
The effect of high temperature on cement slurry is a problem in the oil and gas drilling industry. Over the years, silica flour was used to prevent the strength of cement that results from high temperature effect. But the silica flour is imported and not environmentally friendly. Hence, the need for local material that can serve as alternative becomes imperative. Periwinkle shell (Tympanostomus fuscatus) was tested in the laboratory to determine its potential use in place of the synthetic silica flour. The shell was pulverised, calcinated, and subjected to laboratory test following the require

Abstract:
Gypsum, from either nature or industrial by-products, can be a lower-cost and cleaner alternative binder to Portland cement used in construction projects, such as affordable housing in developing countries. Although various building products have successfully used gypsum as the binder, some drawbacks of this material have still been claimed, for example, in the aspects of mechanical strength and some other physical properties. Using mineral additions to gypsum seems to be a possible solution to create composite gypsum with improved properties. This work has investigated the possibility of two

Abstract:
Temperatures in excess of 110 ºC result in phase transformations of cement, significantly decreasing its compressive strength. This effect is referred to as strength retrogression. It is frequently observed in cement sheaths of heavy oil wells submitted to steam injection. The present study evaluated the mechanical behavior of Special Class Portland Oilwell Cement (SCPOC) slurries containing silica flour to prevent retrogression. A factorial statistical planning was used to assess the effect of the main variables on the mechanical behavior of cement slurries, i.e., mechanical testing temperatu

Catalyst is a substance that is widely used in chemical reactions to obtain certain products. This study has been focusing on preparing and employing solid catalyst derived from geothermal sludge (GS) as waste material from Dieng Geothermal Power Plant (PLTPB) activity. The methodology of catalyst preparation was extraction of silica from the sludge by alkali solution, followed by gelling formation and acidification with sulfuric acid solution. The prepared catalyst was then applied in hydrolysis reaction to convert sago flour into glucose.Catalyst properties were assessed in term of morpholog

Abstract:
Abstract A cement plug is widely applied for permanent abandonment phase to provide long-term zonal isolation against fluid flow. Maintaining cement plug integrity is a challenging task, and loss in cement sealing poses risks to the surrounding environment and surface safety. It is well-known that the cement performance is affected by cement material and downhole conditions. Nevertheless, investigations linking these influencing factors with the sealing of cement plugs are still limited, especially with the lack of proper equipment in the past. In the present work, a small-scale laboratory set

Abstract:
Abstract In the transition from fossil fuels to sustainable, renewable energy sources, development of geothermal energies sources provides an important contribution to ensure the green shift. Per today, most geothermal wells operate at a temperature range of 150–300 °C, but in order to increase power production, a transition to more supercritical conditions (∼500 °C) is needed. It is generally accepted that Ordinary Portland Cement (OPC) is not suitable for supercritical wells. In this paper we report mechanical properties and pressure cycling-test (function tests) results of two alternative C
