Application of Full Waveform Inversion to Time-Lapse Walkaway Vertical Seismic Profile Data for CO2-EOR Monitoring in Abu Dhabi: A Feasibility Study on Field and Synthetic Data

This study aims to investigate the feasibility of CO2-EOR monitoring by full waveform inversion (FWI) of time-lapse VSP data in an onshore CO2-EOR site in Abu Dhabi. CO2-EOR monitoring using conventional time-lapse surface seismic in onshore oil fields in Abu Dhabi is often technically challenging for two main reasons. The first is that elastic property change in response to pore fluid substitution is relatively small because the elastic modulus of the reservoir rock frame is far larger than that of the pore fluids. The second is the low repeatability of time-lapse survey data due to high amplitude surface-related noise which varies temporally. However, seismic monitoring with FWI of time-lapse borehole seismic data may offer a solution for these issues. FWI is capable of detecting small velocity changes such as those associated with pore fluid substitution. Furthermore, borehole seismic surveys may provide more highly repeatable, higher quality data compared to surface seismic surveys because borehole seismic data is less affected by surface-related noise. This study consists of two parts, a field data analysis and a synthetic study. In the field data analysis, we studied the resolution and repeatability of FWI results at field-data quality, including the presence of actual noise using time-lapse VSP data. VSP data was acquired at the very early stage of EOR and there was no CO2 injection in the time between the two time-lapse VSP surveys. As a result, a high-resolution P-wave velocity model, consistent with a sonic log, was obtained. The P-wave velocity model also revealed excellent repeatability between the two survey data sets. In the synthetic study, time-lapse FWI was performed using synthetic VSP data representing pre- and post- CO2 injection periods. The results of the synthetic study showed that even in the presence of realistic 4D noise, which was estimated in the field data analysis, FWI successfully delineated the distribution of velocity changes caused by CO2 injection when the cross-sectional area of the injection-induced velocity changes were larger than the resolution of the FWI results. With these results, we demonstrated that FWI using time-lapse VSP data was applicable for CO2-EOR monitoring in the field as long as the criteria were met. This conclusion encourages the application of FWI using time-lapse VSP data for CO2-EOR monitoring in onshore Abu Dhabi.

COLLABORATION OF THREE STAKEHOLDERS ‘TRISULA’ IN REALIZING THE COMPLETE VILLAGE MAP

The Ministry of Agrarian Affairs and Spatial Planning/National Land Agency (ATR/BPN) is targeting the realization of thevalid complete village map. This strategic program is carried out by mapping all land parcels including physical and juridical data so that an accurate land database can be created. This study aimed to analyze collaborations of three stakeholders: Land Office, City/Regency Government, and Village Government in realizing the complete village map. This study was conducted using a qualitative-descriptive method. Data collection was conducted in three ways: interview, secondary data, and observation field. Data analysis was carried out spatially on the main data and supporting data for the complete village map. The results of the study show that collaboration and data sharing (land registration maps, land value zone map, PBB block map, Regional Spatial Planning (Rencana Tata Ruang Wilayah - RTRW) map, and detailed Village Letter C map) between the three stakeholders are important variables for building the complete village. This study proves that the collaboration of the three stakeholders is able to accelerate the realization of a complete village database with results that match the requirements and criteria set by the Ministry of ATR/BPN. In addition, the data integration that was carried out can be used to create a one data village, which is expected to be able to provide input for the government in formulating policies.

Peran Badan Permusyawaratan Desa dalam Pengawasan Dana Desa

This study was conducted to analyze the role of the Village Consultative Institution (BPD) in monitoring the use of Village Funds in Kuta Pinang Village, Tebing Syahbandar District, Serdang Bedagai Regency. This research uses descriptive qualitative research methods, data collection techniques by conducting literature studies and research in the field. Data analysis was performed by reducing data, presenting data and drawing conclusions. The role of BPD includes three things, namely the role in regulations, organizations / institutions and in individuals. The results showed that the role of the Village Consultative Body (BPD) of Kuta Pinang Village in the supervision of Village Funds by monitoring and auditing financial reports on the use of village funds. The follow-up of the supervision that has been carried out by the BPD which is an evaluation of the performance of the Kuta Pinang village government has also not been available so that the role of supervision has not been optimal. In addition to these aspects, the findings in this study are the obstacles faced by the BPD of Kuta Pinang Village in conducting supervision, namely the lack of community participation in village deliberations, the BPD does not understand the regulations for the use of village funds, BPD resources are still inadequate and inaccurate monitoring documentation, so that the impact on the implementation of supervision is not optimal.

Design of a Technical-Artisanal Dike for Surface Water Storage and Artificial Recharge of the Manglaralto Coastal Aquifer. Santa Elena Parish, Ecuador

Manglaralto parish communities are supplied with drinking water extracted from shallow aquifers (associated with alluvial terraces) recharged by seasonal rivers. The companies responsible for extracting and distributing water are the Manglaralto Regional Drinking Water Administration Board (JAAPMAN, for its acronym in Spanish) and Olon Regional Board of Drinking Water (JRAPO, for its acronym in Spanish). However, due to population growth and tourism (floating population) of Manglaralto parish, water demand has increased. This has meant that, during the dry season, the water stored in these underground reservoirs is not enough to meet the growing demand. The case study presented is that of the Manglaralto community. The aim is to design, in a technical way, an artisanal dyke (tape) by performing geological-geotechnical studies that allow optimal surface storage and artificial recharge of aquifers for the provision of water to communities. The methodology is as follows: i) Analysis of the technical starting information, ii) Recognition of the study site and the choice of sampling sites, iii) Conducting laboratory tests and analysis of information obtained in the field, and iv) Technical design of the tape. According to laboratory results and the field data analysis, the design of a spillway dyke equipped with a dentellon was defined, which acts as a screen to block the subsurface flow. The rescue of ancestral knowledge, used as a solution to current problems in this coastal community, allows storing a volume of 4,641.88 m3 and an artificial recharge of 15%, with low costs and great social acceptance.

Repeatable and reproducible workflows using the RENKU open science platform

<p>Good scientific practice requires good documentation and traceability of every research step in order to ensure reproducibility and repeatability of our research. However, with increasing data availability and ability to record big data, experiments and data analysis become more complex. This complexity often requires many pre- and post-processing steps that all need to be documented for reproducibility of final results. This poses very different challenges for numerical experiments, laboratory work and field-data analysis. The platform Renku (https://renkulab.io/), developed by the Swiss Data Science Center, aims at facilitating reproducibility and repeatability of all these scientific workflows. Renku stores all data, code and scripts in an online repository, and records in their history how these files are generated, interlinked and modified. The linkages between files (inputs, code and outputs) lead to the so-called <span>knowledge graph, used to record the provenance of results and connecting those with all other relevant entities in the project.</span></p><p>We will discuss here several use examples, including mathematical analysis, laboratory experiments, data analysis and numerical experiments, all related to scientific projects presented separately. Reproducibility of mathematical analysis is facilitated by clear variable definitions and a computer algebra package that enables reproducible symbolic derivations. We will present the use of the Python package ESSM (https://essm.readthedocs.io) for this purpose, and how it can be integrated into a Renku workflow. Reproducibility of laboratory results is facilitated by tracking of experimental conditions for each data record and instrument re-calibration activities, mainly through Jupyter notebooks. Data analysis based on different data sources requires the preservation of links to external datasets and snapshots of the dataset versions imported into the project, that is facilitated by Renku. Renku also takes care of clear links between input, code and output of large numerical experiments, our last use example, and enables systematic updating if any of the input or code files are changed.</p><p>These different examples demonstrate how Renku can assist in documenting the scientific process from input to output and the final paper. All code and data are directly available online, and the recording of the workflows ensures reproducibility and repeatability.</p>
