Data is undeniable the foundation to the Oil and Gas 4.0 in the petroleum industry. However, data is not equal to value. The true business lies in extracting and maximizing value out of the available and required data. Data analytical thinking is the key to identify and define the problems, extract values, and develop solutions. This is also the key to transform to a data-driven organization.\u0000 Being data driven involves a combination of people, process and technology. The structure has to be built based on a solid foundation of data driven culture, which requires both technical and soft skills updates. Being data-driven is a teamwork requiring the collaboration between domain experts and data scientists to maximize their strengths. Identifying and defining problems by domain experts is crucial. The traditional working approaches will no longer be sufficient in a data-driven culture. Becoming data sensitive with data analytical thinking will be a necessity especially during the transformation of the traditional petroleum industry.\u0000 The paper illustrates the theoretical concepts of data analytical thinking and discusses the real cases exploiting the dark data and enhancing data collection. The data-driven organization is based on massive data. Fundamentally, the data flows through the process of data collection, quality assurance, data access, data security, and analytics. Every organization is collecting an amount of data much more than ever before. Unfortunately, the collected data could become dark data without proper analytics and utilization. In order to shed light on the importance of data analytical thinking, the paper utilizes the most frequently gathered data, including field production flow testing data and daily field production operational data. Real cases of utilizing eight offshore fields’ Business Plan data are also illustrated. Customized automation data analytical processes with significant boost of working efficiency are also shared to highlight the importance of integrating domain experts and data scientists.\u0000 A data-driven organization makes effective decisions based on the values extracted from massive data. The smooth collaboration between domain experts and data scientists is fundamental to minimize the communication cost.

The reservoir is in the second member of Liushagang formation, of which lithology is mainly argillaceous siltstone, with high shale content, and is characterized by strong heterogeneity with rapid transition of horizontal pay zone, low porosity and permeability, poor oil recovery due to early-stage extraction through conventional well completion and perforation. In order to expand the drainage area of reservoir and improve the connectivity of the reservoir for improvement of control reserves and enhance oil recovery, the research of \"Ultra-short Radius Well Drilling Technology was carried out. The Multi-lateral Ultra-short Radius Well Drilling Technology refers to a novel multi-lateral horizontal well with a radius of curvature of 1~3m or even less, which is completed by special flexible drill pipe composed of mechanical flexible units. Ultra-short Radial Radius Drilling Technology is used in land oilfields in the early stage, which is expected to not only improve recovery and production, but also reduce drilling operation cost, so it is considered as an important measure for enhance oil recovery (EOR), further exploration of residual oil, and stable production in oilfields, and can be suitable for the development of low permeable reservoirs, thin pay zone, and other reservoirs. However, the key challenges include: 1) build-up with dogleg severity of greater than 10°/m; 2) conventional drill pipes cannot meet the demand of high dogleg severity and horizontal drilling. Since there is no case available for reference in the early stage of applying \"Ultra-short Radial Radius Drilling Technology\" in offshore oilfields, besides the aforementioned challenges are for onshore oilfields, other challenges for application of this technology offshore include: (1) Staggering high offshore operation cost, and strict requirement for work schedule. During offshore drilling operation, the footage cost is USD $1850/m, the novel technology is required to be used economically; (2) as for offshore operation, most development wells are deviated, and the trajectory is complex. Since offshore oilfields are mostly developed by cluster wells, and the sidetrack process is subject to well trajectory and dogleg severity.\u0000 In light of build-up with dogleg severity of greater than 10°/m, conventional drillpipes cannot go through the sidetracking point with dogleg greater than 10°/m. As a result, novel \"Ultra-short Radial Radius Drilling Technology\" was introduced by developing a series of novel downhole tools, including highly deviated (23°) Ø209mm whipstock, Ø127mm flexible build-up drillpipe, and Ø144mm build-up bit, combined with selection of sidetracking point, well trajectory design optimizing, and solving difficulties related to operation.

Several recent studies have investigated factors affecting wettability. However, a thorough understanding of all the elements influencing rock wettability remains elusive. Surface wettability is known to be influenced by a range of operating conditions and the surface-related parameters e.g., surface roughness, surface chemistry etc. While these factors have been rigorously reported before, one key factor that received little or no attention is the surface cleavage. In particular, pure calcite mineral demonstrates multiple cleavage plane, and thus wettability of freshly cleaved calcite can vary depending on the cleavage plane, which can also be very different to the wettability of calcite surface exposed to the atmosphere. Moreover, the traditionally reported macro-scale contact angles lack a bit in terms of the identification of three-phase contact line, and thus the use of high-resolution micro-scale approaches for contact angle measurement becomes essential. Thus, in this study, we investigate the wettability of freshly cleaved and exposed calcite and quartz surfaces and examine the difference in the observed wetting behavior. The contact angles were measured at both micro- and macro-scale using a conventional sessile drop method and environmental scanning electron microscopy (ESEM), respectively to also examine any additional impact of the scale of observation. Advanced image analysis algorithm is then used to process the droplet image and examine the contact angles. Additionally, FTIR spectroscopy is also used to determine the surface chemistry changes in the exposed surfaces that would lead to any wettability alteration. The results of this study indicate that the contact angles observed for both freshly cleaved calcite and freshly fractured quartz are much less than the contact angles of the exposed calcite and quartz – suggesting that freshly cleaved surfaces are more hydrophilic than their exposed versions. Thus, much caution should be considered during dealing with calcite and quartz; as exposure time could be a crucial factor in wettability determination.","PeriodicalId":286390,"journal":{"name":"Day 1 Mon, March 13, 2023","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114411818","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}

Due to the difference in coherence between main source and blended noise on the time-space common receiver point gathers, which can be expressed by the sparsity in the FKK domain, we can solve the effective signal by imposing additional constraints on the unknown signal model. The signal model with gradually improved signal-to-noise ratio can be obtained by subtracting interference noise from simultaneous sources. The method has been proved to be efficient and useful in separating the main source from the interference noise by using the Offshore 3d DAS VSP data.

Wettability of carbonate surfaces is typically challenging due to their diverse wetting behavior. Wettability has been conventionally quantified using the macro-scale contact angle observations. However, macro contact angle suffers in terms of precise identification of the three-phase contact line. In this study, a new micro-scale approach is presented to determine rock surface wettability. Here we used five different Middle Eastern carbonate samples with different mineralogy. The micro-scale contact angles are evaluated via Environmental Scanning Electron Microscopy (ESEM) using condensation-evaporation approach while the classical sessile drop method is used to determine the macro-contact angles. The results show a notable difference between macro and micro contact angles which suggests wettability variation at different scale of measurement. Depending on micro contact angles, mixed-wet state for all samples is observed, as some samples experienced water-wet behaviour at most of the measured locations, while they showed intermediate-wet behaviour at a few locations. However, based on macro contact angles, only one wetting behaviour is recognized. Therefore, a thorough wettability characterization would require insights at the micro-scale to capture variations in wetting behavior.","PeriodicalId":286390,"journal":{"name":"Day 1 Mon, March 13, 2023","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127506480","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}
