Gas injection is one of the most common methodologies for Enhanced Oil Recovery (EOR) in the oil and gas industry. One of the challenges associated with gas injection, e.g. natural gas, CO2 and N2, is potential asphaltenes precipitation and subsequent deposition causing blockage throughout the production system. It is crucial that precipitation of asphaltenes is identified early in the planning stage of any EOR project so that mitigation strategies are put in place to avoid negative impact on well performance. A line-drive pattern CO2 pilot is planned in a super giant field A onshore Abu Dhabi and hence single phase bottomhole samples were collected from a nearby well to evaluate asphaltene stability under CO 2 gas injection. This paper presents the results of the lab work that clearly indicate no asphaltene deposition problems during natural production; however, asphaltenes will precipitate when CO2 is mixed with the crude at mole fractions as low as 0.2. Based on the experimental results and on field results from another CO2 pilot in field B, which experienced asphaltene deposition problems, it was deemed necessary to include provisions for continuous downhole chemical injection of asphaltene inhibitors in the CO2 pilot producers for field A. The challenge is to combine the requirements to prevent CO2 corrosion and to prevent asphaltene deposition in the well. The paper describes the different completion design options that can be used to achieve the desired target taking into account the cost impact. The designs incorporate combinations of different tubing materials and chemical injection options with pros and cons to using each, keeping in mind the reservoir monitoring requirements that can add more constraints to the completion design.

This paper shows how individual employee needs and dynamic interactions, relationships and team building initiatives, implemented by ADCO with their EPC CONTRACTOR, have contributed to successfully managing one of their recent projects. The paper looks at the 'Joining Effort' of all personnel for a single interactive dynamic team, whilst considering the Project Management areas of Leadership, Management Structure / Change and Conflict Resolution. An added parameter was to ensure the technical production was to a high standard. From previous projects, major challenges experienced in project management have been many. The issues were all listed with the possible effects project wide. After all the challenges to the 'health of the project' were listed, solutions were identified in the following areas; install strong leadership, management structure/tools in place, one integrated team, taskforce champions, document composition for complex documents, aligning the document production with time, identifying resources shortfall, identifying quality issues, containing cost through design, employee needs and recognition, team building exercises and conflict resolution. Various theories (Maslow, Hertzberg & others) involving emotional, psychological and motivational areas were investigated. These verified that the solutions put in place should work. The results proved positive. Primary points were; attitude change (self esteem/self-actualization), strong trust and low conflict. These aspects led onto many more beneficial results, especially within the team framework. The added 'Technical' parameter looked into the effect of having a technically sound project as compared with a not so technically sound project. There is no Magic for creating the project success that everyone is trying to achieve. But probably it could be described as a magic dynamic formula involving the employee, the team and the technical. The project is on time, to budget, of good quality and with safety covered. Being pro-active and identification of possible problems up front, allows solutions to be put in position. Bringing all personnel (the project teams) together, to act as one unit, is a pre-requisite for this to happen. Copyright 2012, Society of Petroleum Engineers. Source

The purpose of this study is to carry out a participant Return on Investment (ROI) on one of ADCO's (Abu Dhabi Company for Onshore Oil Operations) Talent & Capability Management Division's (T&CMD) most important in-house programme - Leading People Performance (LPP). This programme is delivered by instructors from T&CMD. It is run over 2 modules of four days each. The LPP is designed to enhance the skills of managers by focusing on their ability to create and develop high performing teams and enabling these teams to function at optimal capacity. The programme is targeted at people who predominantly engage in people management responsibilities. Typically the participants will have between 5 to 10 years of relevant work experience and less than 5 years of relevant management experience. Participants are at grade 15 - 17 in a management / team leadership role. An overview of the programme can be found in appendix 1. This study will not only carry out an ROI from Level 1 (reaction) to Level 4 (impact), but will also introduce a Level 5 component (Transfer Climate), which identifies the environmental factors that help or hinder a learner from applying their new knowledge and skills when back on the job. For the purpose of this study the population comprised of LPP attendees from the last three delivery cohorts i.e. 12, 13 and 14. These programmes ran during 2013 and the first half of 2014. The total number of attendees (participants) was 47. © Copyright 2015, Society of Petroleum Engineers. Source

Fluid substitution is used to predict potential changes in seismic data due to production in oil reservoirs. The fluid changes in clastic rocks are often predicted by the Gassmann equation. However, the applicability of Gassmann's equation in carbonates is not well understood. Apparently, part of this failure is due to the violation of the assumption of a constant shear modulus for different fluids (Baechle et al., 2005; Adam et al., 2006), but it is not clear yet. © 2010 Society of Exploration Geophysicists.

Real-life decision problems are often solved by using a very limited set of data points. The computational complexity of such decision problems can be handled easily by using a mathematical entity called stochastic point cloud (SPC). In general, SPC is a form of granular information and is simulated by a data-driven stochastic process. In this study, particular interests are given on normal-distribution-driven SPCs. When the parameters of a normally distributed variable is not clearly known due to the lack of information or due to the multiplicity of regression analysis, it forms a set of SPCs. Three types of such SPCs are described in detail in this study. The effectiveness of such SPCs in solving a real-life decision problem (i.e., how to minimize vehicle emissions in Abu Dhabi Emirate of United Arab Emirates) is also shown. To develop more realistic and man-machine-friendly decision support systems one can use SPCs. © 2010 Elsevier B.V. All rights reserved. Source
