... Synopsis Since there is no published work on the slippage characteristics of positive displacement liquid meters and, since such information is needed by meter operators, the author has undertaken a special meter testing project at East Chicago to furnish information. He describes...

... to eliminate the calibration error of commercially available flow meters that depend on the gas type. Nitrogen, helium, and ethane are used in these measurements. Temperature variations of the flowing gas are recorded, and gas slippage and inertia effects are also taken into account. Our study shows...

... of tectonic origin is more suitable to be performed in tunnels at the depth of tens or even hundreds of meters below the free surface, which allows to decrease the number of external meteorological factors that affect the deformation characteristics of the interblock contact. For example, temperature...

...), the displacements are in the order of meters, no shear testing device available in the world can impose such displacement records on the samples. Furthermore, there is an issue of wave propagation through rock mass during the shaking induced by earthquakes, which should be carefully considered in this respect...

... that excessive stress might possibly be released by slippage along faults. This study demonstrates that stress magnitudes can be constrained by natural fractures and faults quite locally (at a scale of few tens of meters) and also quite regionally (over km scales). The maximum horizontal principal stresses...

... the small-scale reservoir horizon, is presented in Fig 1 a. The resulting (centimeters to meters) heterogeneity of faults and fault model domain, the dimensions as well as all initial and zones be adequately described regarding the typical cell boundary conditions, are shown in Fig 1 b. The material size...

... standard industry SCADA and data analysis software, as well as manually reading power meters. In summary, the operator deemed ten wells highly successful, five marginally successful, and five were not successful. The reasons contributing to success and failure will be expounded upon to obtain higher...

... are inserted into pipes vibracored 2-5 meters into the sea floor where water depths range from 20 to 100 meters. The sensor outputs are transmitted by sea floor coaxial cables to a central platform and then telemetered (in combin- ation with the onshore stations) via telephone line to a recording facility...

... Abstract This paper presents the implementation and value of Virtual Flow Metering (VFM) concepts for Kashagan Field wells. The VFM models are used for real time well performance estimation. The models are expected to be used to detect fluid properties changes, restrictions in the well tubing...

... months of operation has been excellent and within specifications. The high deviation of the well at the meter location, along with a rapid increase in downhole free gas fraction, presented several interpretation challenges, including operation in complex flow regimes and slippage of the oil phase...

... distance between road surface and vertex of the hill is about 100 meters and inclinations of its five edges are all 60°. The hill is mainly composed of four rock stratas, which, from above to below, are clay, shale, sandstone and limestone, respectively. Their thickness are 10 m, 20 m, 20 m and 50 m...

... Abstract Multiphase flow metering is still a challenging research area, especially when flow of immiscible liquids is considered. Actual flow models in oil and water mixtures treat, in most cases, the flow as a homogenous mixture omitting the nature of the dispersion, the slippage between...

... of existence as a function of flow rates and pipe inclination angles, and values for their associated hydrodynamic parameters are crucial in a number of production engineering applications. These include production optimization, optimum string selection, production logging interpretation, -downhole metering...

... Abstract Extensive pore-structure studies reveal that the fabric of shale systems are comprised primarily of micro-nano meter matrix pores and complex natural fractures. Measured permeability of shale samples containing natural fractures varies significantly with different cores in the same...

... in a granite geothermal reservoir. The predominant flow paths in the reservoir were three approximately orthogonal sets of joints with average joint apertures of 10 & meters and with average joint spacings on the order of 1 to 10 -5 meters. For this same reservoir, Pine and Cundall (1985) accurately...

.... Discusses error causes and correction methods, system design and mechanical design. Maximum non-correctable error due to equipment variations is 0.25 meter. Analysis shows up to 1 meter error due to propagation effects. 1.0 PROBLEM DEFINITION 1.1 Offshore Pipe Locating some cases inspection of certain areas...

... to sudden mining induced stress. A small fraction of the recorded seismicity and significant events occur tens to hundreds of meters away from mining, as a result of fault slips along major seismically active shear zones (e.g., Plum Shear, Footwall Shear). These events are generally of large magnitude, pose...

... or behind tubing in dual completion injectors. This paper explains the principal of oxygen activation log and shows its two important applications. Introduction In traditional production logging, spinner flow-meter measures the average fluid velocity of all phases. This is combined with a holdup...
