Published: November 2018

Abstract

Objectives/Scope
While organizations envisage flawless strategies and impeccable objectives to reach their ambitious missions, the unseen blind spot always happen to be the resources through which these objectives or initiatives have to be executed. Specifically with in the resources of people, process and technology, it is the people element that always take the back seat for the primary reason that it's an inside out process as compared to outside in. This paper aims to look at how to possibly solve this age long issue of talent engagement and what necessary easy to implement steps can be taken in order to address the issue with in organizations and thus build a workforce who are not just physically present during work but very much mentally as well. Below are a few objectives and outcomes we aim to achieve through the right implementation of engagement strategies.

Create a Sense of Belonging
Once we manage to create a sense of belonging in the workforce through constructing an ecosystem where everyone feels valued, safe, and empowered; employees will manifest positive attitude in the workplace and strengthen one another thus achieving greater business results with no extra resource.

Brand Identity
often times we tend to forget that our employees are actually the face of our organization and they represent us in every single transaction we make with our stakeholders.

Innovation
With an engaged workforce we have more possibility of concept sharing, interaction and ideation that stems right from the lowest to the top most layers in the organizational ladder.

Retention & Loyalty
This is to prompt the employee to make him / her feel as part of the organization which contributes directly to higher efficiency, lesser leaves and even lesser attrition rate and better visibility for attracting talented workforce.

Sense of Purpose & Happiness
Most importantly Talent engagement is about bridging the gap between the organizational goals and that of the workforce and building a workforce with a sense of fulfillment and happiness.
While organizations give immense consideration in bringing in world class technologies and implementing fool proof processes, the inevitable failure happens due to their inadequate attention to people who will drive the change. In highly challenging times where organizations are forced to consider various initiatives to sustain the show, the importance of Talent Engagement is more prevalent than ever because, the efficient use of talent and resources at large within would pretty much make or break the organization in the time to come.

Abstract
Hydrocarbon subsea pipelines are considered one of the most significant underwater assets. The importance of integrity assurance for such equipment comes from the huge impact on operation continuity, safety hazards and high repair cost. The scope of this paper is to provide a fitness for service assessment on a subsea pipeline with mechanical damage. The pipeline was displaced and dented during an anchor drag incident.
This research analyzes a case study of an oil subsea pipeline which has experienced an excessive displacement and localized dents due to accidental anchor dragging. Three- Dimensional (3-D) Nonlinear Finite Element (FE) model of the anchor dragging was developed. The FE model mimics the incident probable scenarios in order to reproduce the real deformation in the pipeline for further assessment. The results of the FE Model were compared to divers inspection reports to validate and confirm the deformation pattern of the pipeline, dent location and dent profile.
During a routine intelligent pigging of a subsea pipeline, an anomaly was noticed to the cross sectional profile of the line and was interpreted as a dent. Further diving inspection successfully confirmed and characterized the dent geometries and described a severe dislocation of the pipeline. The inspection reports revealed that the dent took place at filed joints girth weld. The incident took place at a crossing location with another oil line. The incident produced local dent in the pipeline, caused damage in many sleepers in the vicinity, displaced the line from its original location and caused local damages of the concrete coating in some locations. The study included a finite element analysis to assess the acceptance criteria of the dent. Excellent agreement between FE analysis results and actual failure was noticed. The FE stress and strain levels were analyzed and compared to the international design codes. Recommendations related to the required repair against de-rating of the line for future safe operation were provided.

Abstract
This paper covers the seven year history of the reservoir drilling campaign offshore Abu Dhabi, from the early use of a solids free, brine/water-based mud to the recent application of non-damaging, non-aqueous fluids with micronized acid-soluble ilmenite. Details are provided on the integration of the filter-cake breakers with the various types of drilling fluids, from dormant drilling fluid additives to delayed, pH and temperature activated breakers. The paper will cover on the operational implementation and lessons learned from applying all these fluids, both in the drilling and completion/breaker placement phases and describes the avenues undertaken to achieve these performance goals.
Data related to well information, reservoir rock type and completion type was gathered and analysed. Fluid Interaction and other studies were performed to determine the suitable fluid type, formulation etc. Various additional things were taken into consideration such as offset well data, drilling requirements, environmental considerations, logging requirements and likely mud damaging mechanisms. Extensive lab tests were conducted, some of which included compatibility of various fluids, return permeability, changes to the oil-water ratio, internal phase composition (heavier CaBr2 instead of CaCl2) and a micronized, acid soluble ilmenite as a weighting agent. The breaker systems saw the same extent of refinement, from enzymes to delayed organic acid precursors and chelating agents to evaluate the removal of the fluid filter cake by the breaker. Fluids formulations were evaluated and optimized based on observations.
Over eighty extended reach drilling (ERD) wells have been drilled using both Reservoir Drill-in Fluid (RDF) systems: water-based mud RDF, and Non-Aqueous Fluid (NAF) RDF, each with specially formulated Breakers. These wells provided lessons learned which contributed to the current design and formulations which are in use today. Friction Factors (FF) obtained using RDF NAF proved to be much lower than those with RDF WBM. The lower friction factors enabled wells with longer horizontal sections within the reservoir to be drilled successfully and at significantly higher Rates of Penetration (ROP). The use of micronized, acid soluble ilmenite also led to achieving lower ECD as compared to sized calcium carbonate. The evolution of breaker formulations also allowed for longer breakthrough time to be obtained which allowed for better coverage of the lateral, better removal of the filter cake, and ultimately enhanced production through improved inflow profiles. The end result of the continuous improvement in reservoir drilling fluid was a first of its kind non-aqueous fluid that combined the desired properties of low rheological profile for ECD management, low coefficient of friction and being non-damaging.
Compaction and Subsidence Assessment to Optimize Field Development Planning for an Oil Field in Sultanate of Oman

Abstract
The Middle to Late Cretaceous Natih formation in Oman can be highly compressible and undergo large compaction during depletion. Significant reservoir compaction and surface subsidence has potential risks for fault reactivation, integrity of wells and surface facilities. Petroleum Development Oman produces oil and gas from the Natih formation in a number of fields within its concession area. There are existing experiences in one of the analogue field in Oman, where the compaction of Natih formation has resulted in issues of well damage, well integrity, subsidence damage to facilities and experiences of surface tremors due to fault reactivation.
The focus of this work was for Fahud West oil field producing oil and gas from a Natih reservoir, where analysis of an analogue field had indicated a high potential impact of compaction. A Geomechanical assessment of the formation within the field was therefore undertaken to mitigate operational risks, and to assess the permeability impact with increased depletion.
The Integrated Geomechanical data acquisition and modeling minimized uncertainty and provided clarity on whether the reservoir can continue with increased depletion – without increased geomechanical risks of loss of integrity for wells and facilities, cap rock integrity or reduced productivity. Properly planned and rock mechanics measurements were conducted in the laboratory on core samples.
The measurements revealed that the expected compaction of Natih reservoir in Fahud West field is less severe compared to the analogue field. The maximum predicted surface subsidence expected at depleted reservoir pressure of 10 bars, is within the tolerable subsidence limit for surface facilities. In addition, permeability measurements showed that the permeability at reservoir pressure of 22 bars (the previous base case for end of production), will not change significantly with further depletion of reservoir pressure to as low as 10 bars.
The outcome of this integrated geomechanical assessment demonstrates that the field can be produced down to 10 bars from the previously estimated 22 bars (base case) limit, adding significant risked volume of oil production, allowing further drilling of wells to raise the final field recovery while ensuring safe well and facility integrity

Published: November 2018

Abstract
For natural gas sweetening, amine based chemical absorption is the most used process. However, large energy requirements in the regeneration of the amine solvent makes this process energy intensive. The concept of heat pump assisted distillation has been known to reduce energy requirements in distillation processes. In this work, we study, simulate and analyze four different configurations for the regeneration of amine employing the concept of heat pump. The studied configurations are based on the concepts of Mechanical Vapor Recompression (MVR) and Self-Heat Recuperation (SHR). The configurations were simulated using Aspen HYSYS software. The configurations were mainly analyzed by comparing their overall energy consumption, overall cooling energy and operational costs. The developed configurations were also compared with the conventional regeneration unit design. The results show that the best obtained configuration uses both MVR and SHR based design of heat pump. The SHR aspect related to further preheating of the feed stream. This resulted in savings in the overall energy consumption, cooling energy and operational costs were 10.11%, 10.92% and 8.28% (savings of about 41,000 $/yr) as compared to a conventional regeneration unit design for this configuration.

Published: November 2018

Abstract
Quantitative lithofacies modeling is an essential part of reservoir characterization that involves recognition of lithofacies along with depth. It is a difficult task due to diverse, nonlinear, high-dimensional, noisy and imbalanced nature of sensory well logs data. To overcome the above-mentioned issues, we propose a novel automatic detection and diagnosis module (ADD), comprising of Wavelet associated Twin support vector machine (TwinSVM) for Quantitative Lithofacies Modeling. ADD module comprises of three stages i.e. pre-processing stage, model development stage, and post-processing stage. In the pre-processing stage, resampling, data normalization, wavelet package denoising, and feature extraction (Relief algorithm) have been performed on input sets for data smoothening and enhancement of lithofacies detection capability of ADD module. During the model development stage, TwinSVM has been trained and tested on processed data obtained from preprocessing stage. The parameters of TwinSVM were properly tuned using Genetic algorithm. The optimized ADD module has also been tested on an additional set of unseen well logs data to validate its effectiveness and reliability during the post-processing stage. The performance of five conventional classifiers models has also been compared with the proposed ADD module. The test outcomes clearly indicate the superiority of ADD module over other conventional classifiers for Quantitative lithofacies modeling.

Abstract
Injection of drilling waste into subsurface formations proves to be an environmentally-friendly and cost-effective waste management method that complies with zero discharge requirements. It has now become the technology of choice in offshore Abu Dhabi.
The aim of cuttings reinjection (CRI) is to mitigate risks associated with subsurface waste injection and reduce cuttings processing time and cost. In order to meet these goals, a cuttings reinjection subsurface assurance methodology was developed to improve cuttings processing and continuously monitor drilling waste injection operations.
Preparing for CRI operations required extensive drilling cuttings slurry testing to minimize processing time and develop optimum particle size distribution to reduce cost and increase the injected waste volume. The improvements were accompanied by downhole pressure and temperature monitoring of the injection well, thus facilitating analysis of injection pressures. Fracture containment was verified through a combination of pressure decline analysis, periodic injectivity test, temperature survey, and periodic modelling for fracture waste domain mapping. A backup injection well was used also as an observation well to monitor the pressure signitures in the injection formation.
More than 1 million barrels of drill cuttings and associated drilling waste have been safely and successfully disposed of into a single injection zone of CRI well over three years of operations.
The cuttings reinjection subsurface assurance method optimizes grinded cuttings particle size distribution, detects and identifies potential risks to provide mitigation options to prolong the life of the injector.
The proactive subsurface injection monitoring-assurance program was built into the fit for purpose CRI injection procedure to continually avoid injecting any rejected hard material, improve and update the process as per subsurface injection pressure responses, thus reducing processing time and cost, mitigating injection risks, and extending the injection well life.
This paper presents the unique and technically challenging cuttings slurry properties design and pressure interpretation experience learned in this project; the enhancement of cuttings processing helped increase injection volumes and an in-depth interpretation of fracture behavior which behaved like a risk-prevention tool with mitigation options. Significant enhancement was developed in slurry treatment procedures to avoid injectivity loss and maximize the disposal capacity.

Abstract
The subject reservoir has been on production for decades and suffered early water breakthrough due to significant geologic heterogeneity. The existing dynamic model was last history matched in 2010, and the match quality had deteriorated over the last few years of production life. Significant volume of new data had become available, including SCAL, cores, wireline logs, production and surveillance data which were recently leveraged to update the static model based on new geomodelling best practices. The justification for progressing to history match the new static model was the business need for a fit-for-purpose tool required to support the life cycle development and management strategy for the reservoir which is evolving from 5-spot flood scheme to line drive utilizing state of the art pilot well technology.
Water channeling is an important phenomenon in the stratigraphically zoned reservoir, and since some of the diagenetic features are co-located at the same intervals, identifying which are key actors for fluid flow was one of the greatest challenges encountered, hence the adoption of fluid travel time concept for mapping and tracking of preferential flow pathways, and for accelerated history match learnings. Intensity attribute measured in count per foot for diagenetic features underpinned spatial permeability modification for model calibration. However, history match changes which include facies intensity modification, footprint and geometry adjustment, permeability magnitude, etc were not just expedient on achieving history match but were all data supported and fed through a closed iterative geo-engineering loop for geologic plausibility and consistency verification prior to been incorporated in the dynamic model.
A good history match was achieved for all calibrated parameters, and the near-perfect vertical conformance prediction of 10 recently acquired water saturation logs is a confirmation of the integrity and predictive capability of the New Generation Model.
Application of STAMP to Process Industry

Abstract

Objectives/Scope
Hazard identification is one of the most important activities carried out in the Safety Instrumented System (SIS) safety lifecycle [1]. Proper hazard identification and analysis of its risk lays the foundation of the SIS design.

Methods, Procedures, Process
The common method for a structured study for the hazard identification is Hazard and Operability Study (HAZOP) study. The concepts of HAZOP are well evolved and applied for over five decades. The basic premise for HAZOP considers plant design is mature enough and sufficient design information on the plant operation is available. HAZOP process involves breaking down of complex process into simpler sections which are termed as nodes. These individual nodes are then studied for identifying the potential hazards and operability problems.
STAMP (System-Theoretic Accident Model and Processing) [2] is accident causality model based on systems theory. STPA (System Theoretic Process Analysis) is one of the STAMP based tool which is a relatively new hazard analysis technique based on an extended model of accident causation. STPA is a proactive analysis method that analyzes the potential cause of accidents during design development so that hazards can be eliminated or controlled. Conventional studies like HAZOP considers deviations or component failures as cause for what may go wrong and cause accident. STPA assumes that accident may also be caused due to unsafe interactions of the system components, none of which have failed.
Data-Driven Analytics: A Novel Approach to Performance Diagnosis Using SpatioTemporal Analysis in a Giant Field Offshore Abu Dhabi

Published: November 2018

Abstract
The field of data-driven analytics and machine learning is rapidly evolving today and slowly beginning to reshape the petroleum sector with transformative initiatives.
This work describes a heuristic approach combining mathematical modeling and associated data-driven workflows for estimating reservoir pressure surfaces through space and time using measured data. This procedure has been implemented successfully in a giant offshore field with a complex history of active pressure management by water and gas.
This practical workflow generates present-day pressure maps that can be used directly in reservoir management by locating poorly supported areas and planning for mitigation activities. It assists and guides the history matching process by offering a benchmark against which simulated pressures can be compared. Combined with data-based streamlines computation, this workflow improves the understanding of fluid flow movements, help to identify baffles and assists in field sectorization.
The distinctive feature of this data-driven approach is the unbiased reliance on field-observed data that complements complex modeling and compute-intensive schemes typically found in reservoir simulation. Conventional dynamic simulation and the tracing of streamlines require adequate static (e.g. permeability tensor) and dynamic models (e.g. pressures for each active cell in the system).
Alternatively data-driven streamlines are readily available and calibrated.
This paper presents innovative algorithms and workflows to the relatively limited existing body of literature on data-driven methods for pressure mapping.
In this case study, new insights are effectively revealed such as inter-reservoir communication, enabled a better understanding of the gas movement and supported the change in production strategy.
The paper is organized as follow. After a general overview of the field studied, this paper describes in detail the workflows used to interpolate pressures in space and time along with cross-validation results. Various applications of the pressure predictions are presented in the sections thereafter.
