An Integrated Approach to Reduce Water Production in the San Andres Formation
Authors: Lati Shrutesh , Alimahomed Farhan , Ferrer Giselle Garcia , Pope Timothy 
Published: August 2017

Abstract
San Andres formation is a dolomitized carbonate and an oil-and gas-bearing member of the Upper Permian in the Permian Basin. It has been produced with vertical wells that were either waterflooded or CO2 injected for primary, secondary, and tertiary recovery. Some of the early waterfloods date back to the 1960s. Historically, the San Andres formation is associated with high water cuts. This paper proposes an integrated solution from planning to completion of a horizontal well, with an aim to control water production. The workflow involves the integration of various technologies such as crosswell seismic, petrophysical logs, geomechanical logs, fracture modeling, and real-time microseismic monitoring.
Stratigraphic surfaces were created using the crosswell seismic data tied in with well tops from offset vertical wells. The 3D model was populated with high-tier petrophysical and geomechanical properties from the pilot well. The zones with high water saturations were identified in the subsurface, which gave an insight into the source of the produced water. Fully 3D planar fracture modeling was performed using the log data from the vertical offset well at the landing point of the horizontal well. Sensitivities were performed on various fluid systems, job volumes, and pump rates, and a playbook was created for real-time operations as part of a contingency plan.
Lateral measurements included petrophysical and geomechanical data, which were used to place perforations, within a stage, in similar type of rock. Depending on the real-time microseismic events, the stimulation design was changed on the fly. Stages with events that were growing out of the zone were modified first, and a final pump schedule was established after the first five stages.
The production results indicated a 20% decrease in water cut, which is a notable improvement compared to the historical production data in the San Andres. The workflow proved that the water production can be significantly reduced by applying a methodology that includes integration of data from multiple domains, thereby improving the economics of a well.
Horizontal Shale Well EUR Determination Integrating Geology, Machine Learning, Pattern Recognition and MultiVariate Statistics Focused on the Permian Basin
Authors: Gaurav Abhishek 
Published: August 2017

Abstract
The objective of this work is to accurately determine horizontal shale well EUR for an area integrating geology, machine learning, pattern recognition and statistical analysis using various parameters of nearby producing horizontal shale wells, as inputs.
This work utilizes local geological information followed by execution of machine learning to identify critical well parameters that lead to better production. Then a pattern recognition step is performed while making sure the number of wells in each category are statistically significant. This also serves as a quality control measure by not basing the conclusion solely on the results of machine learning. The conclusions are verified using available literature on correlation between well production and various well parameters. Wells with optimum (controllable) parameters are selected to obtain a type curve for the target zone(s) in the area of interest.
The above-mentioned methodology helped in making the type-curve/EUR determination process scientific, systematic and seamless. Machine learning helped in identifying the key well-parameters that correlate to better production. Visual pattern recognition strengthened the confidence in the relationships identified in the last step. Different parameters were shown to affect production in different areas/targets confirming that every shale asset requires a thorough research before reaching a reasonable conclusion. The type-curves were established for each Wolfcamp bench in the area of interest selecting wells with optimum completions. The optimum completions parameters were identified by the methodology prescribed in the paper. This assisted in identifying the area of interest's true economic potential with regards to horizontal shale well development.
This paper prescribes a novel scientific data-intensive methodology to systemically use well data in a step-wise manner to identify the type-curve and EUR/well for an area, thereby determining the area's true economic potential.
Along with the prescribed big-data mining methodology, the most important take away from this study is: for the optimum evaluation of shale assets it is critical to tie in the controllable well parameters to well production. Once this relationship is established, the type-curve determination and the EUR estimation can be done more accurately.

Abstract
Like many unconventional plays, the Eagle Ford, once one of the most active shale plays in the world with over 250 rigs running, saw a vast amount of data collected during the boom over a very short time. As with most unconventional resources, a lack of validation of reservoir parameters prevailed in the early history of these plays (emerging plays) and thus, hypothesis drove drilling and completion optimization programs. The 2015 drop in commodity prices accelerated the need to optimize well designs and spacing and stacking patterns in a less capital-intensive manner. A sector model was built that enabled discrete modeling of the 4 development wells in place and significant remaining undeveloped potential to be completed both within and near the sector model area. From this model, substantial understanding around the key parameters driving subsurface performance both from the rock and wellbore design perspectives was gained. As in-fill drilling has occurred in other areas of the play, a learning curve developed around the understanding of vertical connectivity, fracture geometry, well interference and the impact of clusters and job size on fracture contact with the reservoir. This learning curve has been applied to the integrated model to understand what an optimized infill drilling program for the area would look like at various hydrocarbon pricing scenarios.
This paper utilizes an integrated model approach to understand reservoir performance on a pad with four wells completed across multiple horizons in the Eagle Ford. Wireline quad combo compressional and shear log suites (including azimuthal anisotropy and VTI sonic processing, resitivity/acoustic borehole imagers, and NMR), core (geomechanical, geochemical analysis, routine core analysis and specialized core analysis), completion data (fracture treatments with pre-and post-job shut-in pressures), production data (1200 days of production history with a bottom-hole pressure gauge and calculated bottom hole pressures from rod pumps) are used to build petrophysical models, geo-models, geomechanical models, fracture propagation models and reservoir models with the aim of understanding completion and production drivers. A workflow is presented that enables these models to improve our understanding of layering effects (vertical connectivity), fracture asymmetry (pressure sinks or sources), well interference (hydraulic vs. propped lengths) and the impact of clusters and job size on fracture contact with the reservoir.
METODE MEMAHAMI NAṢ-NAṢ TEOLOGIS: Studi tentang Wacana Inklusif Ahl al-Kitāb
Authors: Sakhok Jazilus 
Published: August 2017

This paper examined how to understand the texts of the Qur'an and Ḥadīth concerning the concept of Ahl al-Kitāb. The concept of the Ahl al-Kitāb becomes frequently debatable for there have been contradictions of the texts with other texts. To avoid contradictory understanding, it can be reached by way of compromising various existing texts. Through this method, it reveals that there is no contradictory theological understanding in the Qur'an and Ḥadīth about how Muslims should behave towards and treat Ahl al-Kitāb. From the texts it precisely shows an understanding that Muslims have to give respect, to recommend for doing good, and to acknowledge the existence of the Ahl al-Kitāb as long as each of them does not meddle in the affairs of each faith. The texts also produce a strong message that alludes to an inclusive teaching of Islam towards Ahl al-Kitāb.Tulisan ini mengkaji tentang cara memahami nash-nash al-Qur’an dan Hadis mengenai konsep Ahl al-Kitāb. Konsep Ahl al-Kitāb selalu menjadi per­­­debatan karena seolah-olah telah terjadi kontradiksi di antara satu naṣ dengan nash yang lainnya. Untuk menghindari pemahaman yang kontradiktif, bisa ditempuh dengan cara mengkompromikan dan menjama’kan berbagai naṣ yang ada. Melalui metode tersebut ternyata tidak ditemukan kontradiksi pemahaman secara teologis di dalam al-Qur’an dan Hadis mengenai bagaimana seharusnya umat Islam bersikap terhadap Ahl al-Kitāb. Dari naṣ-naṣ itu justeru me­nunjuk­kan satu pemahaman supaya memberikan respek, menganjurkan berbuat baik, dan mengakui eksistensi Ahl al-Kitāb yang harus dihormati, selama tidak saling men­campuri urusan keimanan masing-masing. Naṣ-naṣ tersebut juga meng­hasilkan pesan kuat akan sikap inklusif ajaran Islam terhadap Ahl al-Kitab.
DIALOG LINTAS IMAN DALAM KOMUNITAS LINTAS BUDAYA (Telaah Diskursif Polemik Ahmadiah dalam Milis Mahasiswa Pascasarjana Universitas Gajah Mada Yogyakarta)

The development of social media has made the world like folded. The actual issues to be so fast and easy to synthetically discussed through a mailing list included in the polemic issue of Ahmadiyah. This paper discussed the genealogy and characteristics of CRCS UGM student mailing list in response to issues of Ahmadiyah in Indonesia and how far it reinforce the idea of archeology students in nurturing empathetic intelligence in internal conflicts of Islam. This study was a library research that relied on documents as objects of study then to do in contents analyzed. The conclusion is in polemics on Ahmadiyah in mailing CRCS indicate an attempt to find "objectivism" and "rationality" in the understanding that the issue be debated Ahmadiyah distintinkly and contextually. But among those showing different domination between objectivism and rationality that sometimes still have not found any common ground between the pro and anti Ahmadiyah although they generally in inclusive way of life. However, the process of intense discussion through the mailing list is very helpful in understanding the sow intelligence building empathy among Muslims especially those who are experiencing conflict.Perkembangan media sosial telah menjadikan dunia bagai dilipat. Isu-isu aktual menjadi begitu cepat dan mudah untuk didiskusikan melului sarana mailinglist (milis) termasuk dalam polemik isu Ahmadiyah. Paper ini mendiskusikan genealogi dan karakteristik milis mahasiswa crcs UGM Yogyakarta dalam merespon isu-isu Ahmadiyah di Indonesia dan sejauhmana hal itu memperteguh arkeologi pemikiran mahasiswa dalam menyemai kecerdasan empatik di tengak konflik intern umat Islam. Penelitian ini merupakan library research yang mengandalkan dokumen sebagai obyek kajiannya kemudian dilakukan analisis isi. Kesimpulannya adalah dalam berbagai polemik tentang Ahmadiyah di milis crcs menunjukkan upaya menemukan “obyektivisme” dan “rasionalitas” dalam memahami polemik Ahmadiyah sehingga isunya menjadi distintif dan kontekstual. Namun diantara mereka menunjukkan dominasi yang berbeda antara obyektivisme dan rasionalitas sehingga terkadang masih dijumpai belum adanya titik temu antara yang pro maupun yang kontra meskipun secara umum nalarnya inklusif. Namun proses diskusi yang intens melalui milis tersebut sangat membantu dalam membangun kesepahaman dalam menyemai kecerdasan empati antar umat Islam terutama yang sedang mengalami konflik.
MENENTANG SEKULARISME: Upaya Membentuk Kesalehan Subjek Muslim di Banten
Authors: Hudaeri Mohamad 
Published: August 2017

Contemporary Islamic movements have undergone many changes of outlook, social and political orientations. The movement is not directed to establish an Islamic state or to support the use of military forces to achieve individual and communal programs in preparing "good Muslims". But the project is directed to self-transformation through moral cultivation and ethics as the foundation to be performed in public spaces. The movement is more directed to the process of reislamization related to social and discipline practices to prepare a good Muslim. This article explores the Islamization of public space in the Banten province. That is related to the construction of Islamic identity of the body and the public place. Construction of Islamic identity of the body is stressed by obliging veils (ḥijāb) for Muslim women. While Islamization of public places is through mounting names of Allah (Asmaul Husna) and other Islamic messages in several major highways.Gerakan Islam kontemporer banyak mengalami perubahan visi dan orientasi sosial dan politik. Gerakan tersebut bukan diarahkan untuk mendirikan negara Islam atau mendukung penggunaan militer dan kekerasan untuk me­wujudkan program menciptakan individu dan masyarakat “Muslim yang baik”. Tetapi proyek tersebut diarahkan untuk transformasi-diri melalui penanaman moral dan etika sebagai landasan untuk bisa tampil di ruang publik. Gerakan tersebut lebih diarahkan kepada proses re-Islamisasi yang berkaitan dengan praktek sosial dan praktek disiplin untuk membentuk subjek Muslim yang baik. Tulisan ini mengeksplorasi tentang Islamisasi ruang publik yang ada di Provinsi Banten. Yakni terkait dengan konstruksi identitas Keislaman terhadap tubuh dan tempat publik. Konstruksi identitas Islam terhadap tubuh ditekankan melalui keharusan untuk berjilbab bagi wanita Muslimah. Sedangkan Islamisasi tempat publik adalah pemasangan nama-nama Allah (Asmā’ al-Ḥusnā) dan pesan-pesan Islam lainnya di beberapa jalan raya utama.

Abstract
Poyang Lake was selected as the research area. Based on laboratory experiment, field investigation and numerical simulation, the spatial distributions of suspended sediment (SS) under the gravity-flow, jacking-flow and back-flow patterns were quantitatively analysed. An annular flume experiment was conducted to determine the critical starting shear stresses of the sediments in the flood and dry seasons. By numerical experiment, the SS transport under different flow patterns was explored. Several results stand out. (1) The critical starting shear stresses of the sediments in the flood and dry seasons were 0.35 N·m−2 and 0.29 N·m−2, respectively. (2) Due to the strongest flow disturbance and scouring effect, SS under the gravity-flow pattern was characterized by the highest loads. The lowest SS was observed during the jacking-flow pattern, which could be attributed to the lowest water level gap between the lake and external rivers. The loads ranged from 0.053 kg·m−3 to 0.068 kg·m−3. (3) Under the back-flow pattern, SS in the north lake was evidently influenced by the Yangtze River, and the mean value was approximately 0.12 kg·m−3. With the gradually weakened back-flow impact, the SS load was decreased from the north to the middle of the lake.
