in this paper, the effect of hydrocarbon fluid properties on water coning in fractured reservoirs, using a black oil numerical simulator has been studied. effect of each parameter has been investigated both separately and also with the construction of different models. using separate constructed models.primarily the hydrocarbon fluid density, viscosity and also water density as effective parame...

Implicit pressure-explicit saturation method (IMPES) is widely used in oil reservoir simulation to study the multiphase flow in porous media. This method has no complexity compared to the fully implicit method, although both of them are based on the finite difference technique. Water coning is one the most important phenomenon that affects the oil production from oil reservoirs having a water d...

Aiming to advance the coning algorithm performance of strapdown inertial navigation systems, a new half-compressed coning correction structure is presented. The half-compressed algorithm structure is analytically proven to be equivalent to the traditional compressed structure under coning environments. The half-compressed algorithm coefficients allow direct configuration from traditional compre...

Typically coning motion has been used as a standard input to assess the performance of the strapdown attitude algorithms. Traditional coning algorithms are based on the Bortz’s first-order rotation vector equation. The algorithm error is composed of two parts: drift error and approximation error. For the three (or more)-sample coning algorithms, calculation indicates that approximation error is...

Coning motion is a standard test input to evaluate the performance of the strapdown attitude algorithms. Angular-rate coning algorithms error consists of two parts: drift error and approximation error. Traditional angular-rate coning algorithms usually improve the algorithm performance by increasing the sampling number in one update period. However the increase of the sampling number can only r...

Laura Island, which is located about 50 km away from downtown, is a source of water supply in Majuro atoll, which is the capital of the Republic of the Marshall Islands. Low and flat Majuro atoll has neither river nor lake. It is very important for Majuro atoll to ensure the conservation of its water resources. However, upconing, which is the process of partial rising of the freshwater-saltwate...
