This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of their wide application within the petroleumindustry it is natural to consider geophysical techniques for monitoringof CO2 movement within hydrocarbon reservoirs, whether the CO2 isintroduced for enhanced oil/gas recovery or for geologic sequestration. Among the available approaches to monitoring, seismic methods are by farthe most highly developed and applied. Due to cost considerations, lessexpensive techniques have recently been considered. In this article, therelative merits of gravity and electromagnetic (EM) methods as monitoringtools for geological CO2 sequestration are examined for two syntheticmodeling scenarios. The first scenario represents combined CO2 enhancedoil recovery (EOR) and sequestration in a producing oil field, theSchrader Bluff field on the north slope of Alaska, USA. The secondscenario is a simplified model of a brine formation at a depth of 1,900m.

Book excerpt: This chapter considers the application of a number of different geophysical techniques for monitoring geologic sequestration of CO2. The relative merits of the seismic, gravity, electromagnetic (EM) and streaming potential (SP) geophysical techniques as monitoring tools are examined. An example of tilt measurements illustrates another potential monitoring technique, although it has not been studied to the extent of other techniques in this chapter. This work does not represent an exhaustive study, but rather demonstrates the capabilities of a number of geophysical techniques on two synthetic modeling scenarios. The first scenario represents combined CO2 enhance oil recovery (EOR) and sequestration in a producing oil field, the Schrader Bluff field on the north slope of Alaska, USA. The second scenario is of a pilot DOE CO2 sequestration experiment scheduled for summer 2004 in the Frio Brine Formation in South Texas, USA. Numerical flow simulations of the CO2 injection process for each case were converted to geophysical models using petrophysical models developed from well log data. These coupled flow simulation geophysical models allow comparrison of the performance of monitoring techniques over time on realistic 3D models by generating simulated responses at different times during the CO2 injection process. These time-lapse measurements are used to produce time-lapse changes in geophysical measurements that can be related to the movement of CO2 within the injection interval.

Available in PDF, EPUB and Kindle. Book excerpt: Geological sequestration has been proposed as a viable option for mitigating the vast amount of CO2 being released into the atmosphere daily. Test sites for CO2 injection have been appearing across the world to ascertain the feasibility of capturing and sequestering carbon dioxide. A major concern with full scale implementation is monitoring and verifying the permanence of injected CO2. Geophysical methods, an exploration industry standard, are non-invasive imaging techniques that can be implemented to address that concern. Geophysical methods, seismic and electromagnetic, play a crucial role in monitoring the subsurface pre- and post-injection. Seismic techniques have been the most popular but electromagnetic methods are gaining interest. The primary goal of this project was to develop a new geophysical tool, a software program called GphyzCO2, to investigate the implementation of geophysical monitoring for detecting injected CO2 at test sites. The GphyzCO2 software consists of interconnected programs that encompass well logging, seismic, and electromagnetic methods. The software enables users to design and execute 3D surface-to-surface (conventional surface seismic) and borehole-to-borehole (cross-hole seismic and electromagnetic methods) numerical modeling surveys. The generalized flow of the program begins with building a complex 3D subsurface geological model, assigning properties to the models that mimic a potential CO2 injection site, numerically forward model a geophysical survey, and analyze the results. A test site located in Warren County, Ohio was selected as the test site for the full implementation of GphyzCO2. Specific interest was placed on a potential reservoir target, the Mount Simon Sandstone, and cap rock, the Eau Claire Formation. Analysis of the test site included well log data, physical property measurements (porosity), core sample resistivity measurements, calculating electrical permittivity values, seismic data collection, and seismic interpretation. The data was input into GphyzCO2 to demonstrate a full implementation of the software capabilities. Part of the implementation investigated the limits of using geophysical methods to monitor CO2 injection sites. The results show that cross-hole EM numerical surveys are limited to under 100 meter borehole separation. Those results were utilized in executing numerical EM surveys that contain hypothetical CO2 injections. The outcome of the forward modeling shows that EM methods can detect the presence of CO2.

This book was released on 2003 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost effective monitoring of reservoir fluid movement during CO{sub 2} sequestration is a necessary part of a practical geologic sequestration strategy. Current petroleum industry seismic techniques are well developed for monitoring production in petroleum reservoirs. The cost of time-lapse seismic monitoring can be born because the cost to benefit ratio is small in the production of profit making hydrocarbon. However, the cost of seismic monitoring techniques is more difficult to justify in an environment of sequestration where the process produces no direct profit. For this reasons other geophysical techniques, which might provide sufficient monitoring resolution at a significantly lower cost, need to be considered. In order to evaluate alternative geophysical monitoring techniques we have undertaken a series of numerical simulations of CO{sub 2} sequestration scenarios. These scenarios have included existing projects (Sleipner in the North Sea), future planned projects (GeoSeq Liberty test in South Texas and Schrader Bluff in Alaska) as well as hypothetical models based on generic geologic settings potentially attractive for CO{sub 2} sequestration. In addition, we have done considerable work on geophysical monitoring of CO{sub 2} injection into existing oil and gas fields, including a model study of the Weyburn CO{sub 2} project in Canada and the Chevron Lost Hills CO{sub 2} pilot in Southern California (Hoversten et al. 2003). Although we are specifically interested in considering ''novel'' geophysical techniques for monitoring we have chosen to include more traditional seismic techniques as a bench mark so that any quantitative results derived for non-seismic techniques can be directly compared to the industry standard seismic results. This approach will put all of our finding for ''novel'' techniques in the context of the seismic method and allow a quantitative analysis of the cost/benefit ratios of the newly considered methods compared to the traditional, more expensive, seismic technique. The Schrader Bluff model was chosen as a numerical test bed for quantitative comparison of the spatial resolution of various geophysical techniques being considered for CO{sub 2} sequestration monitoring. We began with a three dimensional flow simulation model provided by BP Alaska of the reservoir and developed a detailed rock-properties model from log data that provides the link between the reservoir parameters (porosity, pressure, saturations, etc.) and the geophysical parameters (velocity, density, electrical resistivity). The rock properties model was used to produce geophysical models from the flow simulations.

This model represents the most difficult end member of a complex spectrum of possible sequestration scenarios. The time-lapse performance of seismic, gravity, and EM techniques are considered for the Schrader Bluff model. The second scenario is a gas field that in general resembles conditions of Rio Vista reservoir in the Sacramento Basin of California. Surface gravity, and seismic measurements are considered for this model.

Available in PDF, EPUB and Kindle. Book excerpt: These three works cover the entire field of formation evaluation, from basic concepts and theories, through standard methods used by the petroleum industry, on to new and exciting applications in environmental science and engineering, hydrogeology, and other fields. Designed to be used individually or as a set, these volumes represent the first comprehensive assessment of all exploration methodologies. No other books offer the breadth of information and range of applications available in this set. The first volume, Introduction to Geophysical Formation Evaluation, is the perfect introductory reference for environmental professionals without previous training in the field. It explains the fundamentals of geophysical exploration and analysis, illuminates the underlying theories, and offers practical guidance on how to use the available methodologies. General information on material behavior, porosity, tortuosity, permeability, cores, resistivity, radioactivity, and more provides a solid foundation for more advanced studies. The second volume, Standard Methods of Geophysical Formation Evaluation builds on the basic precepts presented in the first work but can be used alone as a self-contained reference. It covers all the petroleum-oriented standard methods which, until recently, have comprised the majority of applications of geophysical formation evaluation. It also points out non-hydrocarbon uses of petroleum methods. This volume provides complete practical information and instructions on using the standard exploration and evaluation methods. It presents comprehensive, painstakingly detailed instructions for resistivity, radiation, and acoustic methods. The third volume, Non-Hydrocarbon Methods of Geophysical Formation Evaluation, discusses uses of formation evaluation in environmental science and engineering, hydrogeology, and other fields outside the petroleum industry, and demonstrates how the standard methods can be adapted to these non-hydrocarbon purposes. It presents step-by-step instructions for photon, magnetic, nuclear, and acoustic methods of exploration, and gives special attention to the analytical techniques used in non-hydrocarbon exploration. Individually, each book is a complete, stand-alone reference on an important area of this changing field. Together, the three volumes provide the most complete practical compendium available on all aspects of formation evaluation.

Available in PDF, EPUB and Kindle. Book excerpt: CO2-Sequestration at the Swiss Molasse Basin, a Myth? A Risk, Geology, Thermodynamic and Geothermic based pre-feasibility Study This study was undertaken within the PSI-LEA Technology Assessment (TA) group's involvement in the project CARMA (Carbon management in power generation). While the original scope of the study was to broaden and deepen previous analyses on accidental risks of Carbon Capture and Storage (CCS), the scope has been widened to include a site-specific assessment of the CCS potential for the location Utzenstorf (canton Berne, Switzerland), and subsequently an extrapolation for the whole Swiss Molasse Basin (SMB) and the adjacent Folded Jura was performed. In contrast to the first-appraisal study by Chevalier et al (2010) ("BfE-Study" of Diamond et al., 2010), our pre-feasibility study and their assumptions were developed to provide an alternative approach, which generally can be considered as more conservative (uncertainties 10-50%), and thus may serve as a lower boundary estimate of the potential for deep geological storage of CO2 in Switzerland. In addition, this study also provides an overview of the current state-of-the-art of equation of states (EOS) that are an essential element for the rational design and operation of CCS-processes, discusses potential synergies and conflicts of CCS and geothermal applications, and finally an estimation of the seal damage probability (SDP) for accidental leakage at a CCS site. Still missing for future investigations are cost-benefit estimations, sensitivity analysis, life-cycle assessment, sociological and environmental impact studies, more appropriate high pressure and temperature EOS of CO2, statistical modelling for "predicting" huge RG sandstones in USM sediments, geophysical detection procedures, 3D hydro geological modelling with CO2 fluids with MODFLOW in USM-sediments - and drillings etc. Less helpful are projects regarding carbonation reactions ("mineral trapping") with minerals Mg-rich-Olivine or -Serpentine, because a lot of LCA studies have shown that this approach is rather insignificant method for CO2 mitigation. Ironically, our results in favour of USM sediments are so superb that we found the same range of number according to storage volume for CO2 (40% of BfE result) like the BfE study predicts. This similarity was not intended as an act of "sociological conformity", rather another example of Talib's "black [grey] swan" property of nature. We think that this study may help to define standard boundary conditions for a (hypothetic) CCS or geothermic regulatory authority in respect of safety margin (pressure built-up, injection rate, request for least sediment properties, water contamination issue). Although, the estimate of the CO2 storage potential is lower than in the BfE-study, it is still a substantial amount that could support several natural gas power plants, which appears sufficient considering the current planning of number of plants as well as that natural gas should serve as a bridging technology. However, the differences in suitability of different layers between the two studies are rather distinct, which should be further investigated in the future to become a clearer picture.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A sensitivity study of gravity and electromagnetic (EM) techniques, and amplitude vs. angle (AVA) analysis for CO2 movement in coal beds was based on the SECARB pilot test planned in the Black Warrior basin in Alabama. In the area of interest, coalbed methane is produced mainly from the Black Creek, Mary Lee, and Pratt coal zones at depths between 400 and 700 m and approximately 3 m thick on average. The permeability of coal in the Black Warrior basin decreases exponentially with depth as overburden stress increases. The permeability of the top layer is 100 mD, while the permeability of the deepest layer is around 1 mD. The pilot field test will include injecting a total of 1000 tons of CO2 into these three coal zones ((almost equal to)300 tons to each zone). The density, sonic and resistivity well-logs from a deep disposal well a couple of miles from the pilot test site were used to create background (pre-injection) models. Our laboratory measurements of seismic velocity and electrical resistivity as a function of CO2 saturation on coal core samples were used to provide a link between the coalbed CO2 flow simulation models and the geophysical models. The sensitivity studies showed that while the response to the 300 tons of CO2 injected into a single layer wouldn't produce measurable surface response for either gravity or EM, the response due to an industrial-size injection would produce measurable surface signal for both techniques. Gravity inversion results illustrated that, provided we can collect high-quality gravity data in the field and we have some a priori information about the depth of the reservoir, we can recover the spatial location of CO2 plume correctly, although with the smoothing constraint of the inversion, the area was slightly overestimated, resulting in an underestimated value of density change. AVA analysis showed that by inverting seismic and EM data jointly, much better estimates of CO2 saturation can be obtained, especially in the third injection zone, where seismic AVA data fail to detect the high CO2 saturation. Analysis of spatial resolution and detectability limits show that gravity and EM measurements could, under certain circumstances, be used as a lower-cost alternative to seismic measurements.
