Social Entrepreneurship As Seen By the Future Managers
Authors: Pereverzieva Anna , Volkov Volodymyr 
Published: November 2020

Present society development faces a significant growth in unemployment in all countries around the world, regardless of the level of their development, and a decrease in income. Instability in the economy causes inability to meet population basic needs at the expense of available opportunities. There is a need to expand social entrepreneurship, launching of social enterprises, whose activities are based on innovative business models with a predominant focus on solving social problems. The entities` management requires training of management professionals able to deal with complex economic and social issues, rather than performing certain functions. The authors argue that it is the propensity / aversion to social entrepreneurship that determines the prospects for its development in a particular country. To test the hypothesis, a questionnaire was developed and a survey of students of different courses in economics and management was conducted. The questionnaire contained questions that allow us to consider the understanding of social entrepreneurship essence, the role of gender in social business, highlight key characteristics of social entrepreneurship and identify prospects for this innovative model through the propensity / aversion to social entrepreneurship.
The study objective is to determine the propensity / aversion to social entrepreneurship in order to outline the future prospects for the formation of a new business model with value orientations on human resources. The results of the study demonstrated the importance of social entrepreneurship amid economic uncertainty and external threats. The vast majority of respondents have propensity and are ready to do business based on the innovative model of socially-oriented business. However, there is a fundamental belief in the psyche of people in economic benefits, but not the combination of social mission with efficiency, which is the basis of social business.
The study could be a starting point for identifying areas to improve managers training through identification of key social orientations, which will help in the future to intensify the development of innovative business models aimed at solving socio-economic problems of a society.

Published: November 2020

Abstract
The purpose of this paper to emphasize the lessons learned by ADNOC Sour Gas of material upgrading in the Shah Sulphur Granulation plant due to severe corrosion of Aluminium components. The Sulphur Granulation plant was commissioned in 2015, the granulation unit consists of a total of 12 packaged granulating systems used for solidifying and granulating the liquid sulphur. The study focused on the corroded areas which are the GX Plenum chambers, lower section of Granulator exhaust stack, Scrubber inlet and discharge ducting.
Root Cause Analysis (RCA) was undertaken to understand and identify the cause of the corrosion. The study indicated that the corrosion of Aluminium components is typical of wet acidic attack. Wet acid is being produced in the granulator drum where atomised liquid sulphur is quenched by demineralized water to produce sulphur granules. The highly acidic vapours further travel to the exhaust stack through scrubber. The paper discusses the typical damage mechanism indicating the source of acidic species, their generation, corrosive attack and mitigation under plant operating conditions.
It has been observed that under full capacity the plant utilized all the 12 granulators, therefore insufficient time for cleaning and acid water disposal. Therefore, Aluminium which is a universally recommended material for sulphur granulation plant is suffering severe material degradation. This has led to go for a detailed material review with process requirement. Entire plant equipment was segregated in 2 parts as per severity of corrosion. After the engineering study, the Plenum chamber and associated piping to scrubber duct will be upgraded with Stainless Steel SS316L having less severe corrosion. The Outlet piping from scrubber to FD fan and Exhaust Stack were affected the most, and it was recommended to replace these areas recommended with GRVE.
The current arrangement with upgradedmaterial will assist all new projects to design plants either with enough unit redundancies for routine cleaning or use more resistant material to combat corrosion.

Abstract
Carbonate formations often require stimulation treatments to be developed economically. Sometimes, proppant fracturing yields better results than acid stimulation. Carbonates are seldom stimulated with large-mesh-size proppants due to admittance issues caused by fissures and high Young's modulus and narrow fracture width. The Magwa formation of Bahrain's Awali brownfield is a rare case in which large treatments using 12/20-mesh proppant were successful after the more than 50 years of field development.
To achieve success, a complex approach was required during preparation and execution of the hydraulic fracturing campaign. During the first phase, the main challenges that restricted achieving full production potential in previous stimulation attempts (both acid and proppant fracturing) were identified. Fines migration and shale instability were addressed during advanced core testing. Tests for embedment were conducted, and a full suite of logs was obtained to improve geomechanical modeling. In addition, a target was set to maximize fracture propped length to address the need for maximum reservoir contact in the tight Magwa reservoir and to maximize fracture width and conductivity.
Sufficient fracture width in the shallow oil formation was required to withstand embedment. Sufficient conductivity was required to clean out the fracture under low-temperature conditions (124° F) and to minimize drawdown along the fracture considering the relatively low energy of the formation (pore pressure less than 1,000 psi). Understanding the fracture dimensions was critical to optimize the design. Independent measurement using high-resolution temperature logging and advanced sonic anisotropy measurements after fracturing helped to quantify fracture height. As a result of the applied comprehensive workflow, 18 wells were successfully stimulated, including three horizontal wellbores with multistage fracturing - achieving effective fracture half-lengths of 450-to 500-ft. Oil production from the wells exceeded expectations and more than doubled the results of all the previous attempts. Production decline rates were also less pronounced due to achieved fracture length and the ability to produce more reservoir compartments. The increase in oil recovery is due to the more uniform drainage systems enabled by the conductive fractures.
The application of new and advanced techniques taken from several disciplines enabled successful propped fracture stimulation of a fractured carbonate formation. Extensive laboratory research and independent geometry measurements yielded significant fracture optimization and resulted in a step-change in well productivity. The techniques and lessons learned will be of benefit to engineers dealing with shallow carbonate reservoirs around the world.

Abstract
Productivity enhancement of tight carbonate reservoirs (permeability 1-3 md) is critical to deliver the mandated production and to achieve the overall recovery. However, productivity improvement with conventional acid stimulation is very limited and short-lived. Tight reservoirs development with down spacing and higher number of infill wells can increase the oil recovery. Nevertheless, poor vertical communication (Kv/Kh &lt; 0.5) within the layered reservoir is still a challenge for productivity enhancement and needs to be improved.
First time successful installation of fishbone stimulation technology at ADNOC Onshore targeted establishing vertical communication between layers, in addition to maximizing the reservoir contact. Furthermore this advanced stimulation technology connects the natural fractures within the reservoir, bypasses near well bore damage and allows the thin sub layers to produce. This technology requires running standard lower completion tubing with Fishbone subs preloaded with 40ft needles, and stimulation with rig on site. This paper presents the case study of the fishbone stimulation technology implemented at one of the tight-layered carbonate reservoir.
A new development well from ADNOC Onshore South East field was selected for implementation of this technology. The well completion consisting of 4 ½ liner with 40 fishbone subs was installed, each sub containing four needles at 90 degrees phasing capable of penetrating the reservoir up to 40 ft. While rig on site, acid job was conducted for creating jetting effect to penetrate the needles into the formation. Upon completion of jetting operation, fishbone basket run cleaned the unpenetrated needles present in the liner to establish the accessibility up to the total depth. Overall, application of this technology improved the well production rate to 1600 BOPD compared to 400 BOPD of production from nearby wells in the same PAD and reservoir. In addition the productivity of the candidate well improved by 2.5 times with respect to near-by wells in the same PAD. Currently, long-term sustainability testing preparation is in progress. This paper provides the details of candidate selection, completion design, technology limitations, operational challenges, post job testing and lessons learned during pilot implementation. In summary, successful application of this technology is a game changer for tight carbonate productivity enhancement that improves the overall recovery along with optimizing the drilling requirements. Currently, preparation for implementation of 10 pilots in one of the asset at ADNOC Onshore fields is in progress.
Reducing Carbon Footprint Through Wellsite Processing
Authors: Innes Gareth , Morris Andrew 
Published: November 2020

Abstract
Global carbon emission reduction targets and how to meet them are high on operators’ agendas. Quantifying greenhouse gas (GHG) emissions created across every segment of the hydrocarbon extraction and production value chain is an essential step in this process.
It's already widely acknowledged by operators on the UK Continental Shelf that drill cuttings treatment at the well site can materially reduce costs and improve safety by avoiding the need to collect, contain and transfer cuttings by sea and road freight to a specialist processing facility onshore, as required using the traditional "skip and ship" method. It's also widely accepted that by reducing the transport and logistics involved in skip and ship processing, carbon emissions are also greatly reduced, but by exactly how much had not been precisely quantified.
In order to support operators’ understanding of their carbon footprints towards drilling waste management specifically, TWMA performed a study to establish the comparative carbon footprint for a portable thermal processing drill cuttings processing unit, treating drill cuttings on a standard offshore platform, versus that of a typical skip and ship to shore operation.
The study investigated the carbon footprinting process, interpreted recognised guidance and set system boundaries and emission scopes. The carbon footprint associated with each method of treatment was then calculated, based on carbon dioxide equivalent (CO2e) per tonne of drill cuttings functional unit. Furthermore, a carbon calculator was created to establish a carbon footprint comparison capability for any well within the North Sea.
The results revealed that the carbon footprint of the current skip and ship operation is 53% higher than that of a portable unit treating drill cuttings at typical North Sea well site. Furthermore, and based on the lower estimate of drill cuttings produced on the UK Continental Shelf, additional benefits will include: the diversion of 28,000 tonnes of waste powder from landfill; the recovery of 6000 m3 of produced oil for re-use in the offshore drilling system; and 6000 m3 of water that requires no further wastewater treatment.
This study is the first of its kind to show a direct CO2 comparison between offshore processing and the skip and ship cuttings disposal method. It has increased the awareness of the CO2e emissions associated with each process. As the industry moves towards a lower carbon future, it provides a solution to significantly reduce the carbon emissions of drilling operations whilst also improving safety and reducing well cost.
Utilizing Natural Frequency Monitoring and Machine Learning to Monitor and Predict Structural Integrity and Minimize the Cost of Fixed Offshore Platform Intervention

Abstract
The objective of this paper is to present a method for monitoring the natural frequency of a fixed offshore platform and to utilize the raw data to proactively monitor and predict structural degradation of the platform using machine learning. This can enable operators to predict critical member failure and guide timing of operational decisions and interventions, thus helping reduce cost of ownership, particularly for ageing assets.
A Natural Frequency Response Monitoring (NFRM) system utilizes accelerometers and Fast Fourier Transform (FFT) to measure the sway and torsional frequencies of a fixed offshore platform. A significant structural event is detected by a shift in the natural response of the platform.
A machine learning model (or digital twin) can be trained on this accelerometer data to replicate the platform response and determine the fatigue damage accumulation in platform members. The model, which can be re-trained to maintain accuracy, acts as a near real-time fatigue tracker with the NFRM system acting as a verification tool.
A proof of concept case study is presented and demonstrates how Finite Element Analysis (FEA) simulations and measured data can be used to develop a machine learning model.
The combination of an NFRM system with machine learning has the potential to assist operators in the prediction and identification of structural changes prior to them becoming critical. Knowledge of the actual fatigue damage in key platform members on a near real-time basis allows for proactive planning of inspections or repairs, as well as confidence in the structural performance of the platform, which can justify life extension.

AbstractThe assessment of a Petroleum System includes several steps, which comprise: detailed evaluation ofsource rock, charge history, trap, seal and reservoir. As a result, a multi-scale and multi-disciplinary approach was necessary to obtain a final cohesive product. This paper aimed to improve basin modelling and prospectivity evaluation thanks to the integration of structural geology analysis, geochemical analysis, petrophysical analysis, geophysical interpretation of seismic data, stratigraphic correlations and reservoir quality evaluations. An area in onshore SE Abu Dhabi was chosen for the 12-months Petroleum System Study, where fiveteams underwent rigorous technical work independently and in combination. All the analyzed data were combined to define potential leads and prospects and assess the areal risking at different stratigraphic intervals. The limitation of data availability on the eastern side of the study area, affected the confidence of the main results, but we were able to accomplish an advanced view of the risk and opportunity in the exploration for hydrocarbons within onshore SE Abu Dhabi.The Thamama F reservoir, TH_LK_3 (Lekhwair Formation), has been identified as a key explorationtarget. Thamama F is also a good regional migration carrier bed due to (1) high continuity and very good reservoir properties and, (2) it has a thick very continuous regional top seal. The Thamama B reservoir zone (TH_KH_2 – Kharaib Formation), Thamama A reservoir zone (TH_SH_1 – Shuaiba Formation) and Habshan Formation (HA_2, Sequence 3) also have good exploration potential but the POS at these intervals is relatively lower.Overall, leads in the SSE Abu Dhabi are impacted by a higher risk on hydrocarbon charge, principally due to long distance migration from the source kitchen to the north. Stratigraphic leads have been identified in the Shuaiba Formation, specifically the Upper Bab Member (TH_SH_3) and the Habshan (HA_2). They are high risk but high reward exploration opportunities, which require further work to de-risk.A detailed study of this kind has not been conducted before within onshore SE Abu Dhabi. The outcome of this extensive technical work resulting from the integration of the six distinct sub-surface disciplines and the integrated approach allow us to mature drillable prospects, which will surely be of interest for any other operating company in the same area or in different areas.

Abstract
The application of MHFHW (multistage hydraulic fracturing horizontal well) enormously contributes to the dramatic increasing production of low permeability reservoir. Geomechanics is the key factor for fractured well by influencing SRV (stimulated reservoir volume) and post-stimulation production. Stress variation and distribution characteristics along with real-time fracturing are simulated based on 4D (four-dimension) geomechanics research, providing the effective technical support for the designing and optimization of hydraulic fracturing scheme to get larger SRV and higher post-stimulation production. 1D (one-dimension) geomechanics model is firstly built using data from drilling, mud log, well log, mini fracture and well testing, and then verified by comparing with drilling events and laboratory test of core samples. Furthermore, Project team combines 1D geomechanics model with additional data including 3D structural model, fault distribution and seismic data to achieve the regional 3D (three-dimension) geomechanics model. 3D Geomechanics model only represents the original stress field that before hydraulic fracturing, which will be changed by pumping massive fracturing fluids into reservoir. 3D geomechanics model study is integrated with the data from real-time fracturing and micro- seismic monitoring to generate 4D geomechanics model, enabling the characterization of variation of geomechanics model with real-time fracturing. 4D Geomechanical research result clearly characterizes the stress model variation and reduces the uncertainties in reservoir stimulation operation. The model helps to optimize pressure pumping rate, volume of proppant and fracturing fluids, eventually maximizes the increase of fracture flow conductivity and post-stimulation production., This case study discusses the multi-stages fracturing treatment scheme optimization of horizontal well H84001 based on the 4D Geomechanical research of this low permeability reservoir. H84001 production has improved 184.2% compared with the offset well without fracturing treatment optimization. This project established the mathematical relationships between reservoir deformation and strain, upgrading geomechanical study methods from static to dynamic. The research finding provides technical guidance to develop low permeability reservoir in an economical and efficiency stimulation scheme.
