Abstract
Underbalance perforation is one of the best practices to insure less damage to the perforation tunnels. Many papers described the effect of the underbalance perforation either static or dynamic on the cleanup of the perforation tunnel based on the King et al correlation presented in (1986). A complete understanding of the effect of both magnitude and duration of the underbalance during the perforation will help petroleum engineers to design a perforation job and achieve the maximum benefit of the perforation in connecting the well bore to the reservoir. A new approach to control not only the amount of the underbalance, but also the duration of this underbalance, has been applied in one of North Kuwait sandstone reservoirs. The results showed the duration of the underbalance during perforation has a significant effect on clean up the perforation tunnel.
Reduction and elimination of the perforating damage (perforating skin) ensures increased well productivity. Previously, the basic technique to clean perforation tunnels in order to decrease perforating damage was static underbalance. The static underbalance has been upgraded to dynamic using a down-hole production valve. The down-hole pressure data was collected by a fast reading down hole pressure sensor with 120,000 reading per second, capable of responding and recording virtual instantaneous pressure changes in the wellbore. A combination between dynamic and static underbalance has been configured to maximize the near well bore clean up around the perforation tunnel. A compressed gas, a packer setting depth and surface release valve were configured to control the duration of the static underbalance.
The results show a 50% improvement in well productivity compared with the other wells completed in the same layers. The technique provided optimum volume and duration of the underbalance for all layers with up to 500 psi difference in reservoir pressures. Since this technique was being used for the first time in this reservoir, several perforating simulations were run and evaluated to select the optimum scenario for this well. A deep perforation charge has been loaded in the optimum gun size to maximize the amount of the dynamic underbalance.
This paper will present the new technique of underbalance to give a clean perforation tunnel and evaluation of the impact compared to the conventional perforation techniques through pressure data and well modeling.

Abstract
In order to characterize the influence of diffusion effect, stress sensitivity, matrix shrinkage and adsorption layer on shale gas permeability, weighted coefficient is used to establishdiffusion permeability model by couple transition diffusion and Knudsen diffusion. And the effect of matrix shrink, stress sensitivity and adsorption layer are considered into shale gas permeability model. The shale gas permeability model is verified by permeability experiment result of shale core in Ordos basin and discussing the effect of each parameter. The results showed that: (1) When the weighted coefficient- Km, n and m is 7, 4 and 16 respectively, the proposed diffusion permeability highly agrees with Fick diffusion, transient diffusion and Knudsen diffusion, that can represent diffusion of the whole flow stage.(2) Under the conditions of low pressure and small pores, diffusion flow is the main control factors of shale gas transmission; and under the condition of high pressure and large pores, viscous flow mainly controlling shale gas transmission.(3) The influence of stress sensitivity and adsorption layer on shale gas permeability is bigger, and the influence of the matrix shrink can be ignored.(4) Adsorption layer have a significant impact on the shale gas permeability under the conditions of high pressure and small pores. The proposed shale gas permeability model can eliminate the deviation result from describing the shale gas diffusion only by using Knudsen diffusion model, and also can describe the shale gas transmission under a multi-physic field, and thus it is significantly enlighten the development of shale gas.

Abstract
Electromagnetic methods are a promising technology that allows measuring spatial distribution of resistivity in the inter-well region; its deployment has the objective to map and monitor fluid distribution deep into the reservoirs, kilometers away from the surveyed wells.
There are many challenges in the interpretation of resistivity distribution in terms of fluid saturation. The management of the uncertainties in the knowledge of reservoir properties in the inter-well regions is very critical to the petrophysical interpretation of the resistivity surveys. Most reservoir characterization and saturation tools provide data at specific locations in the reservoir, with a limited radius of investigation around wellbores, typically cores, production and well logs data. This study introduces a novel approach in interpreting electromagnetic surveys and producing robust saturation maps that can guide reservoir management policies, with the ultimate objective of increasing hydrocarbon recovery. The developed workflow will apply dynamic simulation and advanced uncertainty quantification methods.
The uncertain parameter considered is the permeability which is assumed to be spatial uncertainty. Two methods were applied to efficiently quantify uncertainty in the permeability its effect on the salinity distribution. The first method is the probabilistic collocation method (PCM). The PCM is based on the use of polynomial chaos expansion, which is used to develop a polynomial proxy model. The coefficients of this model are determined by performing reservoir simulation using an optimized set of collocation points, which approximate the sample space. The number of these samples that are required are significantly fewer than those required for a typical Monte Carlo or Latin Hypercube Simulation. The second method is the Multi-Level Monte Carlo (MLMC) method, which is based on the use of a combination of multi-level sequentially coarsened (upscaled) grids which shift most of the computational cost to the coarsened grids while minimizing the computational cost of running the simulator on the finer grid level. The results obtained showed that it is possible to investigate a wide range of uncertainty in a computationally efficient manner providing more robust saturation maps compared to current practices.

The aim of this article was to classify The Indonesian Scholastic Aptitude Test or Tes Bakat Skolastik (TBS) results for each subtest and describe scholastic aptitudes in each subtest. The subject of this study was 36,125 prospective students who took the selection test in some universities. Data analysis began by estimating testees’ ability using the Item Response Theory, and benchmarking process using the scale anchoring method applying ASP.net web server technology. The results of this research are four benchmarks (based on cutoff scores) on each subtest, characters which differentiate potential for each benchmark, and measurement error on each benchmark. The items netted give a description of the scholastic aptitude potential clearly and indicate uniqueness so that it could distinguish difference in potential between a lower bench and a higher bench. At a higher bench, a higher level of reasoning power is required in analyzing and processing needed information so that the individual concerned could do the problem solving with the right solution. The items netted at a lower bench in the three subtests tend to be few so that the error of measurement at such a bench still tends to be higher compared to that at a higher bench.
