In the midst of an energy crisis, coal remains essential to the energy mix of many countries. Over time, coal reserves inevitably deplete, and as a result, coal mining progresses, and mines are closed and abandoned. Abandoned mines continue to emit methane for many years after closure, yet their emissions remain uncontrolled and unmonitored in many coal-producing regions. Closed mines may offer a small but significant opportunity to exploit a clean energy resource, known as Abandoned Mine Methane (AMM), which can ...

Drilling fluids are essential for safe and efficient oil and gas well construction, performing critical functions such as cuttings transport, pressure control, borehole stabilization, and bit lubrication. Traditional manual testing according to API standards provides only intermittent data, often leading to delayed responses and increased risks of kicks, lost circulation, stuck pipe, or formation damage – especially in complex unconventional, deepwater, and high-pressure/high-temperature wells. This paper propos...

The article presents data on the role of organic matter as the primary source of oil and gas formation. It provides a general overview of scientific research on the theory of the organic origin of hydrocarbons. The methodological part of the study is based on guidelines for determining the distribution patterns of organic matter in formations of various types, using the values of the formation-equivalent. The formation-equivalent is understood as the aggregation of all forms of organic matter of any type into a co...

Existing industrial ammonia production installations operating in potentially explosive atmospheres usually contain a wide range of explosion protection concepts implemented during different stages of plant modernization and expansion. In such brownfield installations, the coexistence of equipment originating from different technological periods often leads to a non-uniform distribution of protection concepts at installation level. This aspect is particularly relevant for industrial sectors associated with oil and...

The proposed presentation details a newly developed well integrity packer solution that provides a permeant non-elastomeric barrier and can be installed as easily as existing technologies, but offers the unique advantages of a permeant cement barrier. Traditional elastomeric swell packers are a practical, easily installed and proven well construction product, but they have their performance limitations, especially over a well’s lifetime. The cementitious swell packer (CSP) is a product intended to supplement or ...

The presence of flammable and/or combustible substances in various industrial production processes generates in most cases potentially explosive atmospheres, which transforms a regular work environment into an explosion risk area, directly influencing the way in which equipment intended to be used in these areas is designed, installed and maintained. In areas where potentially explosive atmospheres may form due to the presence of flammable and/or combustible substances, technical equipment must be used whose casin...

Natural gas leaks in residential buildings represent a major risk of explosion and fire, endangering lives and property. Current detection systems, predominantly individual and non-centralized, exhibit significant limitations regarding response time, precise leak localization, and effective notification of authorities. This paper proposes the architecture of a centralized system, based on Internet of Things (IoT) technology, for the real-time monitoring of methane (CH4) emissions in medium-sized multi-family resid...

Potentially explosive atmospheres constitute a major risk in the operation of industrial installations that use or generate gases, flammable vapours or combustible dust. According to ATEX legislation, explosions can occur as a result of the interaction between an explosive atmosphere and an active ignition source. Even under the conditions of using ATEX-certified equipment, the progressive degradation of the components can lead to the appearance of uncontrolled ignition sources. This paper analyzes from a technica...

Percussive-rotary drilling remains the preferred method for penetrating hard abrasive rocks (UCS > 150–350 MPa) in mining, exploration, and geotechnical applications. Tungsten carbide (WC-Co) inserts, with their exceptional hardness and abrasion resistance, serve as the primary cutting elements, enabling efficient rock fracturing through combined impact and shear. This study examines tool performance, wear mechanisms (abrasive grooving, fatigue spalling, binder erosion), and optimization strategies including car...

Enhanced Geothermal Systems (EGS) represent one of the most promising high-enthalpy renewable energy technologies for regions lacking natural hydrothermal reservoirs. Poland, positioned on favorable geological structures including the Variscan basement, sedimentary basins, and several high-heat-flow provinces, has emerged as a candidate for EGS deployment. Recent numerical modeling, petrophysical research, and CO2-EGS feasibility studies in Poland indicate strong potential for both heat and electricity generation ...
