Available in PDF, EPUB and Kindle. Book excerpt: Traditional well logging methods, such as resistivity, acoustic, nuclear and NMR, provide indirect information related to fluid and formation properties. The “formation tester,” offered in wireline and MWD/LWD operations, is different. It collects actual downhole fluid samples for surface analysis, and through pressure transient analysis, provides direct measurements for pore pressure, mobility, permeability and anisotropy. These are vital to real-time drilling safety, geosteering, hydraulic fracturing and economic analysis. Methods for formation testing analysis, while commercially important and accounting for a substantial part of service company profits, however, are shrouded in secrecy. Unfortunately, many are poorly constructed, and because details are not available, industry researchers are not able to improve upon them. This new book explains conventional models and develops new powerful algorithms for “double-drawdown” and “advanced phase delay” early-time analysis - importantly, it is now possible to predict both horizontal and vertical permeabilities, plus pore pressure, within seconds of well logging in very low mobility reservoirs. Other subjects including inertial Forchheimer effects in contamination modeling and time-dependent flowline volumes are also developed. All of the methods are explained in complete detail. Equations are offered for users to incorporate in their own models, but convenient, easy-to-use software is available for those needing immediate answers. The leading author is a well known petrophysicist, with hands-on experience at Schlumberger, Halliburton, BP Exploration and other companies. His work is used commercially at major oil service companies, and important extensions to his formation testing models have been supported by prestigious grants from the United States Department of Energy. His new collaboration with China National Offshore Oil Corporation marks an important turning point, where advanced simulation models and hardware are evolving side-by-side to define a new generation of formation testing logging instruments. The present book provides more than formulations and solutions: it offers a close look at formation tester development “behind the scenes,” as the China National Offshore Oil Corporation opens up its research, engineering and manufacturing facilities through a collection of interesting photographs to show how formation testing tools are developed from start to finish.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As for designing its appropriate development scheme, it is crucial to accurately determine petrophysical properties (e.g., absolute and relative permeability) of a hydrocarbon reservoir, both of which can be traditionally determined either by performing steady-state or unsteady-state experiments or by conducting conventional well tests. However, the laboratory method is time-consuming and its measurements may not be representative for the field-scale cases. Since the conventional well testing theories are based on single-phase flow, it is a challenging task to accurately obtain relative permeability for multiple phases in porous media. Alternatively, flow rates together with pressure responses collected from a wireline formation testing (WFT) tool can be used to interpret absolute and relative permeability as well as capillary pressure of a given formation. Physically, capillary pressure plays an important role during multiphase flow for the WFT measurements, though its effect on the permeability interpretation has not been addressed. In this study, techniques have been developed to simultaneously interpret absolute permeability and relative permeability together with capillary pressure in a naturally fractured carbonate formation as well as to simultaneously interpret three-phase relative permeability and water-oil capillary pressure in a tight carbonate formation from WFT measurements. By using pressure and flow rate field data collected by a dualpacker WFT tool, high-resolution cylindrical near-wellbore numerical models are developed for each dataset. After validating grid quality, simulations and history matching are performed for both the measured pressure drawdown and buildup profiles, while absolute permeability is determined and relative permeability is interpreted with and without considering capillary pressure for the naturally fractured formation. As for the tight carbonate formation, water-oil relative permeability, oil-gas relative permeability, and water-oil capillary pressure are interpreted based on power-law functions and under the assumption of a water-wet reservoir and an oil-wet reservoir, respectively. Subsequently, three-phase relative permeability for the oil phase is determined by using the modified Stone II model. Compared with the experimentally measured values, relative permeability interpreted with consideration of capillary pressure has a better match than those without considering capillary pressure in the naturally fractured carbonate formation. In such a formation, absolute permeabilities in the vertical and the horizontal directions of the upper layer are determined to be 201.0 mD and 86.4 mD, respectively, while those of the lower layer are found to be 342.9 mD and 1.8 mD, respectively. Such a large vertical permeability of the lower layer reflects the contribution of the extensively distributed natural fractures in the vertical direction. In the tight carbonate formation, both the relative permeability and the capillary pressure of a water-oil system interpreted under an oil-wet condition match well with the measured values, while the relative permeability of an oil-gas system and the three-phase relative permeability bear a relatively high uncertainty. Not only is the tight reservoir determined as oil-wet, but also the initial oil saturation is found to impose an impact on the interpreted water relative permeability under an oil-wet condition. Changes in water and oil viscosities and mud filtrate invasion depth affect the range of the movable fluid saturation of the interpreted water-oil relative permeabilities.

Download or read book Evaluation of Reservoir Properties From Wireline Formation Test in Multilayer Reservoir written by Duenpen Palasarn and published by . This book was released on 2006 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, a reservoir simulator was used to determine pressure responses from wireline formation tests for single-layer and multilayer reservoirs. Then, a well test interpretation software was used to estimate reservoir parameters. A single layer homogenous reservoir was used as a base case to investigate the effect of test duration, probe position, and formation permeability. Next, multilayer models were simulated and interpreted in order to obtain reservoir properties under different conditions. A reservoir model consisting of two layers of an equal thickness but with different values of permeabilities was constructed in order to determine the effect of the contrast permeability between layers and its order. The averaged permeabilities of multilayer reservoirs based on three averaging techniques were compared to the interpreted results. All the investigations were performed to determine whether the results from WFT conducted in multilayer systems can provide satisfactory information under different reservoir scenarios and tool limitation.
