Available in PDF, EPUB and Kindle. Book excerpt: Laminae included in rock samples are small-scale heterogeneities that introduce anisotropy to the larger-scale rock system. They can be described in terms of grain size variations, as in a clastic sediment that is interbedded with shale layers. Such variations in grain size translate into variations in pore and pore-throat size distributions, and they control the effective two-phase fluid transport properties of the rock. Ultimately, they impact hydrocarbon recovery. This thesis implements an experimental workflow to study and quantify the impact of laminations on dynamic petrophysical properties in the presence of two distinct types of layering: cross and parallel. Accordingly, relative permeability and capillary pressure are measured under two flow conditions: across (perpendicular flow) and along layers (parallel flow). Two cylindrical composite rock samples were fabricated in which the first composite sample was interbedded with a lower permeability rock (Berea sandstone interbedded with Kentucky sandstone), and the second one was interbedded with a higher permeability rock (Kentucky sandstone interbedded with Berea sandstone) to represent the layering cases defined above. Multiple laboratory experiments were carried out to measure mercury intrusion capillary pressure (MICP) and saturation-dependent relative permeability. These measurements were complemented with micro-computed tomography images and nuclear magnetic resonance (NMR) measurements. For the perpendicular flow experiments, I sealed the sub-samples into a cylindrical sample in order to allow mercury to flow across them. The seal surrounds the samples and forces mercury to intrude only through the two ends (faces) of the composite samples. In the parallel flow experiments, I first sealed each piece individually and then sealed the entire stack. This was done to ensure that flow pathways between the pieces were sealed. A bimodal pore-size distribution in the Berea interbedded with Kentucky and in the Kentucky interbedded with Berea samples was revealed by MICP measurements in the parallel layering composite cores. In the cross-layering experiments, I observed a bimodal pore-size distribution for the two rock arrangements. Relative permeability was higher in the parallel flow composite cores compared to the perpendicular flow composite cores. In core data analysis, samples are taken from intervals considered representative of one single rock type. When the data are quality checked, petrophysical measurements from samples that exhibit grain laminations are often excluded. This bias propagates to simulation work and leads to results that often do not match field data

Download or read book Quantitative Borehole Acoustic Methods written by X.M. Tang and published by Elsevier. This book was released on 2004-01-27 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic logging is a multidisciplinary technology involving basic theory, instrumentation, and data processing/interpretation methodologies. The advancement of the technology now allows for a broad range of measurements to obtain formation properties such as elastic wave velocity and attenuation, formation permeability, and seismic anisotropy that are important for petroleum reservoir exploration. With these advances, it is easier to detect and characterize formation fractures, estimate formation stress field, and locate/estimate petroleum reserves. The technology has evolved from the monopole acoustic logging into the multipole, including dipole, cross-dipole, and even quadrupole, acoustic logging measurements. The measurement process has developed from the conventional wireline logging into the logging-while-drilling stage. For such a fast developing technology with applications that are interesting to readers of different backgrounds, it is necessary to have systematic documentation of the discipline, including the theory, methods, and applications, as well as the technology's past, present, and near future development trends. Quantitative Borehole Acoustic Methods provides such documentation, with emphasis on the development over the past decade. Although considerable effort has been made to provide a thorough basis for the theory and methodology development, emphasis is placed on the applications of the developed methods. The applications are illustrated with field data examples. Many of the acoustic waveform analysis/processing methods described in the book are now widely used in the well logging industry.

Download or read book Improved Estimation of Pore Connectivity and Permeability in Deepwater Carbonates with the Construction of Multi Layer Static and Dynamic Petrophysical Models written by Ferreira. Elton Luiz Diniz and published by . This book was released on 2014 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method is presented here for petrophysical interpretation of heterogeneous carbonates using well logs and core data. Developing this new method was necessary because conventional evaluation methods tend to yield inaccurate predictions of pore connectivity and permeability in the studied field. Difficulties in the petrophysical evaluation of this field are related to shoulder-bed effects, presence of non-connected porosity, rock layers that are thinner than the vertical resolution of well-logging tools, and the effect of oil-base mud (OBM) invasion in the measurements. These problems give rise to uncommon measurements and rock properties, such as: (a) reservoir units contained within thinly bedded and laminated sequences, (b) very high apparent resistivity readings in the oil-bearing zone, (c) separation of apparent resistivity logs with different depths of investigation, (d) complex unimodal and bimodal transverse relaxation distributions of nuclear magnetic resonance (NMR) measurements, (e) reservoir units having total porosity of 0.02 to 0.26 and permeability between 0.001mD to 4.2D, (f) significant differences between total and sonic porosity, and (g) low and constant gamma-ray values. The interpretation method introduced in this thesis is based on the detection of layer boundaries and rock types from high-resolution well logs and on the estimation of layer-by-layer properties using numerical simulation of resistivity, nuclear, and NMR logs. Layer properties were iteratively adjusted until the available well logs were reproduced by numerical simulations. This method honors the reservoir geology and physics of the measurements while adjusting the layer properties; it reduces shoulder-bed effects on well logs, especially across thinly bedded and laminated sequences, thereby yielding improved estimates of interconnected porosity and permeability in rocks that have null mobile water saturation and that were invaded with OBM. Additionally, dynamic simulations of OBM invasion in free-water depth intervals were necessary to estimate permeability. It is found that NMR transverse relaxation measurements are effective for determining rock and fluid properties but are unreliable in the accurate calculation of porosity and permeability in thinly bedded and highly laminated depth sections. In addition, this thesis shows that low resistivity values are associated with the presence of microporosity, and high resistivity values are associated with the presence of interconnected and vuggy porosity. In some layers, a fraction of the vuggy porosity is associated with isolated pores, which does not contribute to fluid flow. An integrated evaluation using multiple measurements, including sonic logs, is therefore necessary to detect isolated porosity. After the correction and simulation, results show, on average, a 34% improvement between estimated and core-measured permeability. Closer agreement was not possible because of limitations in tool resolution and difficulty in obtaining a precise depth match between core and well-log measurements.

Download or read book Reservoir Quality of Clastic and Carbonate Rocks written by P.J. Armitage and published by Geological Society of London. This book was released on 2018-06-18 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reservoir quality is studied using a wide range of similar techniques in both sandstones and carbonates. Sandstone and carbonate reservoir quality both benefit from the study of modern analogues and experiments, but modelling approaches are currently quite different for these two types of reservoirs. There are many common controls on sandstone and carbonate reservoir quality, but also distinct differences due primarily to mineralogy. Numerous controversies remain including the question of oil inhibition, the key control on pressure solution and geochemical flux of material to or from reservoirs. This collection of papers contains case-study-based examples of sandstone and carbonate reservoir quality prediction as well as modern analogue, outcrop analogue, modelling and advanced analytical approaches.
