Available in PDF, EPUB and Kindle. Book excerpt: Miscible carbon dioxide flooding is an effective EOR technique for the displacement of reservoir oil after primary and secondary oil recovery methods have been exhausted. Miscibility is achieved either through a first-contact or multi-contact process. The dynamic multi-contact process involves exchange of components between oil and solvent gas through vaporizing and/or condensing drives ultimately resulting in lower interfacial tension and oil viscosity thereby improving oil displacement. By definition the minimum miscibility pressure (MMP) is the pressure at which miscibility is achieved; operating below MMP will drastically reduce hydrocarbon recovery while operating above MMP will add additional costs to the project with little or no additional recover. The main focus of this study is to design and implement a Rising Bubble Apparatus (RBA) for system MMP identification. The various scenarios to be tested include dead Oil C-pure CO2, live Oil C-impure CO2, and dead Oil C-impure CO2. Vanishing interfacial tension (VIT) results are also analyzed and compared to RBA results; recommendation can then be made to identify the most consistent and accurate method of MMP estimation. When applying the VIT method, the MMP's for the three cases were determined to be 10.7 MPa for the dead Oil C-pure CO2 system, 12.3 MPa for the live Oil C-impure CO2 system, and 21.2 MPa for the dead Oil C-impure CO2 system. When applying the RBA method, the MMP's were determined to be 12.0 MPa for the dead Oil C-pure CO2, 12.5 MPa for the live Oil C-impure CO2 system, and 25.0 MPa for the dead Oil C-impure CO2 system. The two methods yield similar results, however values of MMP from RBA experiments tend to be slightly higher.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, several qualitative and quantitative technical criteria are examined/developed and applied to determine the minimum miscibility pressures (MMPs) of different light crude oilCO2 systems from four experimental methods, i.e., the slim-tube tests, coreflood tests, rising-bubble apparatus (RBA), and vanishing interfacial tension (VIT) technique. First, five slim-tube tests with the live light crude oilCO2 system and five coreflood tests with the dead light crude oilCO2 system are conducted at different injection pressures and the actual reservoir temperature of Tres = 53.0C. It is found that different MMPs can be obtained from the same measured oil recovery factor (ORF) vs. injection pressure data if different MMP criteria, regression methods, and threshold values or intersection options are adopted. Thus the determined MMP is better given in a small pressure range than specified as a definitive pressure value. By means of the ORF and break-over pressure (BOP) criteria, two MMP ranges of the live and dead light crude oilCO2 systems are determined to be 15.215.4 MPa from the slim-tube tests and 12.412.9 MPa from the coreflood tests at Tres = 53.0C, respectively. Second, two separate series of pure and impure CO2-bubble tests in a light crude oil column with the RBA are conducted at six different test pressures and Tres = 53.0C. The MMPs of the light crude oilpure and impure CO2 systems are estimated and compared by using four existing (i.e., the bubble shape, size, colour, and rising height) and new bubble break-up (BBU) qualitative criteria with the RBA. It is found that the BBU criterion is consistent with the four existing qualitative criteria for estimating the MMPs. Furthermore, by means of newly developed bubble-rising height (BRH) and bubble-rising velocity (BRV) quantitative criteria, two respective MMP ranges of the light crude oil-pure and impure CO2 systems are found to be 11.7-12.4 MPa and 23.4-23.5 MPa at Tres = 53.0C. Third, six series of the dynamic interfacial tension (IFT) tests for the dead and live light crude oilCO2 systems are conducted under different test conditions. Two new linear correlation coefficient (LCC) and critical interfacial thickness (CIT) technical criteria are developed to determine the MMP when the LCC is smaller than 0.990 or the interfacial thickness is smaller than 1.0 nm for the first time. The determined MMPs of 12.9 MPa and 13.2 MPa for the dead and live light crude oilCO2 systems from the VIT technique by using the two new criteria agree well with 12.412.9 MPa for the former system from the coreflood tests but poorly with 15.215.4 MPa for the latter system from the slim-tube tests. In addition, the specific effects of three important experimental factors on the determined MMPs are studied by using the two new technical criteria: the initial vs. equilibrium IFTs, oil composition, and initial gasoil ratio (GOR) in volume. It is found that the measured initial rather than equilibrium IFTs are accurate enough to determine the MMP from the VIT technique. The live light crude oil pre-saturated with CH4-dominated hydrocarbons has a slightly increased MMP, in comparison with the dead light crude oil. Moreover, the initial GOR effect on the MMP is found to be negligible in a lower GOR range (1:110:1 in volume) or in a large CO2 concentration range (31.7694.69 mol.%). It becomes pronounced in a higher GOR range (200:14000:1 in volume) or in an extremely small range of high CO2 concentrations (98.7999.99 mol.%).

This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Developing Alaskan heavy oils resources has become necessary as, the production from light oil fields in Alaska's North Slope (ANS) is on the decline. Due to the extremely viscous nature of these heavy oils, they are hard to produce by natural pressure. Miscible gas injection Enhanced Oil Recovery (EOR) can be one of the methods for production of these heavy oils. Minimum miscibility pressure (MMP) is an important optimization parameter for EOR processes involving CO2 or hydrocarbon gas injection. The MMP for a gas-oil system is directly related to the interfacial tension between the injected gas and the reservoir crude oil. In this study, a new technique called Vanishing Interfacial Tension (VIT) was used to measure MMP at reservoir conditions. Experiments were conducted using various gas-oil systems to determine the MMP. The experimental results were modeled using the Peng-Robinson Equation-of-State (EOS) with a commercial simulator (CMG). The Peng-Robinson EOS was tuned with experimental data to predict the MMP accurately. This study has demonstrated the accuracy of the VIT technique in predicting MMP by pendant drop method experiments and simulations using CMG software."--Leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Within the last 10 years the world has come to a point where the easily explorable oil deposits have now been found, and it is anticipated that such deposits will be depleted by the beginning of the Twenty-first Century. However, the increasing demand of man kind for energy has caused technologists to look into ways of find ing new sources or to reevaluat:e unconventional sources which, in the past, have not been economical. In this respect, heavy crude and tar sand oils are becoming important in fulfilling the world's energy requirements. What are heavy crude and tar sand oils? There is still some confusion as to their definitions, inasmuch as they vary among organizations and countries. In an effort to set agreed meanings, UNITAR, in a meeting in February 1982 in Venezuela, proposed the following definitions (see also Table 1): 1. Heavy crude oil and tar sand oil are petroleum or petroleum like liquids or semi-solids naturally occurring in porous media. The porous media are sands, sandstone, and carbonate rocks. 2. These oils will be characterized by viscosity and density. Viscosity will be used to define heavy crude oil and tar sand oil, and density (oAPI) will be used when viscosity measurements are not available. 3. Heavy crude oil has a gas-free viscosity of 100-10000 mPa.s (cp) 3 o at reservoir temperatures, or a density of 943 kg/m (20 API) 3 o o to 1000 kg/m (10 API) at 15.6 C and at atmospheric oressure.

This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in analytical chemistry have turned it into a virtually unrecognizable science compared to a few decades ago, when it lagged behind other sciences and techniques. However, advances in analytical science have been far from universal: while innovations in instrumentation and data acquisition and processing systems have reached unprecedented levels thanks to parallel breakthroughs in computer science and chemo metrics, progress in preliminary operations has been much slower despite their importance to analytical results. Thus, such clear trends in analytical process development as automation and miniaturization have not reached preliminary operations to the same extent, even though this area is pro bably in the greatest need. Improvement in preliminary operations is thus an urgent goal of analytical chemistry on the verge of the twenty first century. Increased R&D endeavours and manufacture of commercially available automatic equipment for implementation of the wide variety of operations that separate the uncollected, unmeasured, untreated sample from the signal measuring step are thus crucial on account of the wide variability of such operations, which precludes development of all-purpose equipment, and the complexity of some, particularly relating to solid samples. Supercritical fluid extraction opens up interesting prospects in this context and is no doubt an effective approach to automatioI1 and mini aturization in the preliminary steps of the analytical process. The dramatic developments achieved in its short life are atypical in many respects.
