The aim: To analyze the available literature on most common daily urological problems in menopausal women and to evaluate use of hormone replacement therapy for troublesome symptoms. Materials methods: Analysis publications from PubMed databases disorders during menopause was performed urog¬ynaecological postmenopausal were selected according data. Different methods treatment these compared. Conclusions: During menopause, struggle with many unpleasant symptoms genitourinary system. For...
Summary The result of these works are detailed mechanical earth models for wells within the area investigation and description behaviour interpreted CSF under variable stress state as well understanding connectivity natural fractures zone subjected to fracturing treatment.
The main objective of this study is to present calculation methods horizontal stress profiles, taking into account the boundaries model, poro-elastic strain model and effective ratio approach, using calibration with wellbore failure. mechanical earth (MEM) parameters from log measurements well testing data were estimated for a located in southeastern part Upper Silesian Coal Basin. Log-derived stresses are commonly treated as final product geomechanical modelling oil gas practices. A less...
The geomechanical modeling turned out to be an essential component of the hydrocarbon exploration assisting reduction risk drilling issues and optimization hydraulic fracturing treatment. This study provides a workflow critically stressed fracture (CSF) analysis dedicated for coal layers. main focus paper is applying 1D mechanical models following modelling treatment describe behavior under impact stresses at wellbore scale. Another objective presented demonstration benefits 3D CSF...
Abstract The present study is the result of a technical collaboration undertaken by RAK Gas (the national energy company Emirate Ras Al Khaimah, UAE), PGNiG PKN ORLEN (current operator Block 5, Figure 1) and CGG. research focuses on Paleogene Pabdeh Group, thick sediment package that filled accommodation space developed during Northern Emirates foreland basin evolution (Figure 2). main goal was to create an integrated stratigraphic framework regional understanding Late Cretaceous...
Summary The study focuses on an integrated analysis of stress directions and magnitudes for a deep borehole (D-1) located in the active orogen. integration available geophysical data allowed as to distinguish three structural units penetrated by investigated borehole, which were taken into account geomechanical modelling. developed SigmaG software us determine (1D Mechanical Earth Model) within D-1 assuming linearly variable strain values recognized tectonic units. additionally checked...
The investigated lithological profiles were subdivided into three lithofacies: sandstone, mudstone and shale. Every subdivision was assigned different compaction curve which corresponds to the suitable porosity - depth relation. Moreover, due intensive Neogene thrusting faulting movements, divided tectonic zones. Core data dipmeter measurements helped distinguish particular deformation events. Earlier studies have highlighted separate, from each other NTCL for single zone. Pore...
Summary In this study, the Mechanical Earth Model MEM was built for a vertical exploration well within Wielkie Oczy Graben in order to investigate origins of encountered overpressure zone Miocene age Mb1 strata generally normally pressured homogenous profile. It interpreted that at depths approx. 3100–3250 m, there is layer sand surrounded by relatively impermeable shale which could be responsible centroid effect. Due fact three-dimensional form, it impossible describe on basis wellbore...
<p>The Leak-Off Test (LOT) is one of the most common fracture pressure/Shmin calibration measurements conducted in wellbores. Well engineers rely on readings from LOTs to design safe drilling plans. The LOT results indicate maximum mud weight or equivalent circulating density that can be used drill next hole section without causing fluid losses formation. Losses are expensive issues mitigate operations. In more severe cases, may lead subsequent challenges such as collapse...
Summary This paper focuses on rock strength modelling improved by combining triaxial compressive tests with the Schmidt hammer method and well log data basis of core samples comprising several lithological types (sandstones, mudstones, coal, shales). The proposed methodology provides cost-free measurements without destruction core. Hammer is an application that enhances characterization heterogeneity along sampled section for adjustment mud weight window in next better calibration mechanical...
Summary Drilling cuttings become meaningful source of geological data, over the last few years. Application portable XRF devices at rig site, secures acquisition substantial real time data which enhance while drilling interpretations conducted by operations and exploration geologists, petrophysicists, geophysicists engineers. Considering benefits methodology, geochemical logging (GLWD) survey has been implemented on exploratory well drilled in tectonically complicated setting Outer...
Abstract Geomechanics is the study of how subsurface rocks deform or fail in response to changes stress, pressure and temperature. Therefore, geomechanics an important input for optimal exploration development hydrocarbon reservoirs. The Zechstein formations exhibit different rock deformation behaviours due varying sequences evaporites that cause significant drilling challenges, increasing time associated costs. Commonly used 1D analytical geomechanical models have been inadequate explaining...
Artykuł dotyczy wykorzystania technologii wiercenia otworów kierunkowych – tzw. intersekcyjnych, które Polskie Górnictwo Naftowe i Gazownictwo SA wykonało w ramach prac badawczych prowadzonych latach 2016–2021. Projekt miał na celu wykorzystanie nowoczesnych próbach rozpoznania złóż niekonwencjonalnych formacji węglowych o niskiej przepuszczalności niskim ciśnieniu złożowym, otworami wierconymi z powierzchni terenie Górnośląskiego Zagłębia Węglowego. Przedstawiono zasadę gromadzenia się gazu...
This paper presents a shale gas field geomechanics case study in the Peri-Baltic Syneclise (northern Poland). Polish Oil and Gas Company drilled vertical well, W-1, stimulated Silurian target. Next, horizontal W-2H, Ordovician target partially collapsed. The remaining interval was stimulated, microseismic monitoring performed. A second W-3H, at same azimuth as but well collapsed upper section (Silurian). geomechanical earth model constructed that matches drilling experiences failure...
