Chandra","doi":"10.5220/0009359902910298","DOIUrl":"https://doi.org/10.5220/0009359902910298","url":null,"abstract":": Sand problem is one of the obstacles happening in oil and gas wells, especially in poorly consolidated formation. flowing fluid will generate friction force during flow in porous media and in a longer timeframe, it can erode the wall of formation and sand will be produced along with the hydrocarbon and become problem in the whole production system. The negative impacts of this sand start from eroding the tubing wall until entering the surface facilities, such as separator. Due to this problem, the damaged equipment needs to be fixed or maintained, which means additional cost. Frac-pack is one of completion methods which is quite popular nowadays in oil and gas industry due to its proven effectiveness of utilization in the field. Frac-pack is a combination between hydraulic fracturing and sand control. Utilization of gravel pack only will cause additional skin for wellbore, leading to decrement of well productivity index. In frac-pack, the hydraulic fracturing process will cover the losses and reduce the skin generated. Therefore, sand problem can be mitigated, and production also can be compensated. This study will observe frac-pack, starting from its history, mechanism and effectiveness to be applied in M Well. The gravel pack size will be calculated first and is used as fun-damental of proppant size selection. Then, fracturing process simulation is done using commercial software generating fracture width and fracture half-length. The result will be used to calculate final well productivity by considering skin generated. This research has proven that productivity can be enhanced by using frac-pack until 5.23%. Therefore, frac-pack can be an effective choice of sand control completion method in M Well.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121070950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along with that, the game development process has been dramatically improved by the emergence of free to use game engines. One of the most used game engines worldwide is Unity. Unity provides strong features to support its developers, one of them is the ability to use plugins. Meanwhile, tile-based games are also very popular. Without support from any kind of plugins, development of tile-based games will increase development time, especially in level editing process. Readjusting each tile to a perfect position while it is being added to Unity scene view is very time-consuming. This plugin aims to solve this problem by extending the Unity editor script. This plugin provides support for creating and deleting tiles, enables the developers to cut the time needed to create levels in tile-based games.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123934240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One EOR method that is proven to be able to increase large oil yield is mixed CO2 injection. In implementing EOR CO2 injection mixed, the Minimum Reliability Pressure (MMP) value is the key to success. One of the problems faced by oil fields in Indonesia in carrying out EOR of mixed CO2 injection is that the reservoir pressure has dropped due to old age making it difficult to inject with MMP pressure above the reservoir pressure. The solution that can be done to overcome this is by reducing the MMP value using Liquified Petroleum Gas (LPG).This study will determine the optimal method of LPG use to reduce CO2 injection MMP values from Field X fluid in South Sumatra. Then, the MMP value in various conditions will be determined using a slimtube simulation which will be used to make a correlation to determine the MMP value. From the results of the study, in principle mixing LPG with CO2 will reduce the MMP value optimally. In addition, the average MMP value dropped by 29.5% with an increase in the composition of LPG in the gas mixture of CO2 LPG injection by 30%, the MMP value increased by 23% with a change in hexane plus molecular weight of 27.5% higher than before, and the MMP value increased by an average of 13.4% with an increase in temperature of 20%.The resulting correlation is formed using parameters that have a significant influence on the determination of the MMP value. The resulting correlation has R-Squared of 98.65%. The correlation is then tested with MMP values previously determined through a slimtube simulation and produces an Average Absolute Relative Error (AARE) value of 4.52%. Correlation was then re-tested against the correlations of other MMP determinations using 9 fluid MMP data from other literature. The result is the proposed correlation produces an AARE value of 10.82%.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131667813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IHC is used to determine the status of Estrogen Receptor (ER) and/or Progesterone Receptor (PR). The bonding reaction occurring between the cell and the painting results in the color of the nucleus cell being blue which signifies the negative and brown ER/PR hormone for positive ER/PR. The given hormonal therapy will be effective to breast cancer patients if they have positive ER/PR receptors. Up to now the Anatomy Pathology specialist calculatses the percentage of positive cells that have been marked semiquantitatively. This is time-consuming, costly, subjective and tedious, thereby impacting the length of time required in determining appropriate therapy for breast cancer patients. This study analyze the image of IHC breast cancer to determine the assessment of ER/PR hormone receptor using image processing. The use of kernels of different sizes shows differences in the results of cell segmentation in connective tissue. The use of 3 × 3 and 1 × 1 kernels has indeed succeeded in removing cells in the connective tissue, but not all cells in the connective tissue can be identified.
