Improving the convergence rate of seismic history matching with a proxy derived method to aid stochastic sampling

History matching is a very important activity during the continued development and management of petroleum reservoirs. Time-lapse (4D) seismic data provide information on the dynamics of fluids in reservoirs, relating variations of seismic signal to saturation and pressure changes. This information can be integrated with history matching to improve convergence towards a simulation model that predicts available data. The main aim of this thesis is to develop a method to speed up the convergence rate of assisted seismic history matching using proxy derived gradient method. Stochastic inversion algorithms often rely on simple assumptions for selecting new models by random processes. In this work, we improve the way that such approaches learn about the system they are searching and thus operate more efficiently. To this end, a new method has been developed called NA with Proxy derived Gradients (NAPG). To improve convergence, we use a proxy model to understand how parameters control the misfit and then use a global stochastic method with these sensitivities to optimise the search of the parameter space. This leads to an improved set of final reservoir models. These in turn can be used more effectively in reservoir management decisions. To validate the proposed approach, we applied the new approach on a number of analytical functions and synthetic cases. In addition, we demonstrate the proposed method by applying it to the UKCS Schiehallion field. The results show that the new method speeds up the rate of convergence by a factor of two to three generally. The performance of NAPG is much improved by updating the regression equation coefficients instead of keeping it fixed. In addition, we found that the initial number of models to start NAPG or NA could be reduced by using Experimental Design instead of using random initialization. Ultimately, with all of these approaches combined, the number of models required to find a good match reduced by an order of magnitude. We have investigated the criteria for stopping the SHM loop, particularly the use of a proxy model to help. More research is needed to complete this work but the approach is promising. Quantifying parameter uncertainty using NA and NAPG was studied using the NA-Bayes approach (NAB). We found that NAB is very sensitive to misfit magnitude but otherwise NA and NAPG produce similar uncertainty measures

The Implementation of Student Team Achievement Division and Talking Stick on Economics Subject

The change that happens in human is due to the learning process that makes when someone is studying, then, the better the response decreases. However, it is not consistent with those observed during the teaching practice SMAN 2 Batu. The problem is in terms of liveliness that the lack of participation of student during the learning takes place while in terms of achievement only 40% of student who passes the daily tests, while 60% did not pass. If that is allowed, then most students will not be able to continue to a higher class. Meanwhile, this study is conducted to determine the implementation of Student Team Achievement Division (STAD) and Talking Stick in order to enhance the activity and student achievement of Economic in SMAN 2 Batu. This study is a qualitative study. Data Student Team Achievement Division (STAD) and Talking Stick drawn from learning sheet, data was taken from the student activity sheet student activity and learning achievement is taken from the pretest and posttest.Keywords: Effectiveness.

Relasi Gender dalam Pernikahan Keturunan Sayyid di Desa Cikoang Kabupaten Takalar; Studi Kasus Perbandingan Hukum Islam Dan Hukum Adat

Islamic law holds that the concept of kafaah comes from various aspects, namely religion, descent, property, and face. Among these four things, Sharia prioritizes religion as the main yardstick in determining the concept of kaffah. On the other hand, customary law views that the marriage of sayye descendants in a society still maintains their familiarity, system and belief in the descendants of the Prophet Muhammad. rules that have become absolute and nothing can be seen. However, the marriage system becomes a problem because it can exclude women, and their rights as women. The purpose of this study was to examine and trace the ins and outs of the Sayye marriage system so that gender relations were born among the Sayye community. The research method used is field research and is qualitative and comparative. Sources of data used in this study come from primary and secondary data. The result of this research is that the form of Sayyid's marriage gender relation has the right to determine in his lif
