Abstract A successful primary cement operation within a narrow pore-fracture pressure window presents a significant challenge in the industry. Equivalent circulating density (ECD) during cement operations can cause losses or gains, which can add significant risk to zonal isolation objectives and increase …

Abstract Purpose and content of paper High-temperature geothermal wells introduce severe coring challenges, including jamming in fractured formations, thermal degradation of elastomers, and poor recovery in abrasive or igneous lithologies. This paper presents the geothermal specific design coring system - a rubber-seal-free, …

Mineralogy is essential for accurate reservoir characterization. The quality of laboratory testing methods - such as wavelength-dispersive X-ray fluorescence (WD-XRF), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) - is critical for reliable mineral quantification. This study compares results from four commercial …

Carbon storage projects require both reservoir characterization and reservoir modelling to adequately describe the reservoir. One key component to both requirements is relative permeability data. However, CO2-Brine relative permeability testing has proven to be challenging in the laboratory, often resulting in extended …

Abstract For elastic–plastic materials that can undergo large deformations, the general theory of Green and Naghdi is supplemented by incorporating a novel three-factor decomposition of the deformation gradient. A certain unique right stretch tensor emerges as an appropriate variable for describing finite …

Summary The intricate architecture of the remobilized and injectite sand (RIS) complex in the Balder field, significant velocity variations within the overburden geology, a rugose carbonate underlying strata, and production-related effects have made seismic imaging and interpretation challenging. The use of ultradeep …

Abstract Well log data are essential for subsurface interpretation, reservoir characterization, and quantitative evaluation throughout the exploration and production lifecycle. Accurate and continuous log measurements underpin lithology identification, petrophysical analysis, geological model calibration, and reservoir simulation. However, many wells suffer from incomplete, …
