Perforating is a fundamental operation in completion of oil wells, aiming to communicate the reservoir to the well through explosive loads. Perforating can be divided into three types, according to the system pressure: overbalance, underbalance and extreme overbalance. In the overbalance technique, the hydrostatic pressure (completion fluid) is greater than the static pressure of the formation. In the underbalance technique, the pressure in the well is less than the pressure of the…

Technologies, Av. Do Contorno, 5351, S. 1503, 30110-923 Belo Horizonte, MG, Brazil a r t i c l e i n f o a b s t r a c t This paper presents results of research into the use of factorial experimental design for constructing sensitivity as well as functionally oriented models for power system planning, operation, and control. The rationality of applying factorial experimental design for this goal is associated with the possibility to ‘‘build’’ secants but not tangents (how it is…

Luis Arribas de Paz, Félix Avia, Luis Cano, Ignacio Cruz, Enrique Soria Department of Renewable Energies CIEMAT Phone: +34-91-346 6422 - E-mail: felix.avia@ciemat.es Summary The new annex H of the standard IEC 61400-121 for Power Performance Testing of Small Wind Turbines (now in the approving process) was applied at CIEMAT test centre, on the…

has benefited from refinements of specific RHD targets that ensure accuracy, which has been adopted by the International Society for Blood Transfusion (ISBT) Working Party on Red Cell Immunogenetics and Blood Group Terminology. The immediate goal of testing foetal RHD in maternal plasma is to avoid the use of invasive procedures to assess the risk of HDFN, with the option of returning alloimmunised pregnant women to their primary care physician when the foetus is predicted to be…

Generating Test Traffic Many network performance tools generate their own network traffic to determine the current performance of the network. This technique requires math skills, as well as a knowledge of network theory. All network performance tools that analyze network performance by generating test traffic require two devices on the network. The network performance along the path between the two devices is determined by using the packet pair and packet train methods, described previously in

heterogeneous and anisotropic porous media in any orthogonal coordinate system within a regular boundary domain. A source term, dependent on position and time, was included in the partial differential equation to represent production and/or injection wells. A general boundary condition is considered to account for a constant pressure boundary, a no-flow boundary (symmetry or impermeable boundary) or any prescribed flow boundary. The Generalized Integral Transform Technique (GITT) was…
