Evaluasi Pemilihan Electric Submersible Pump (ESP) Untuk Menggantikan Gas Lift (GL) Di Sumur X Lapangan Offshore Y

Well X is located in the offshore Y field, where there are 7 production wells, all of which use an artificial lift in the form of a gas lift. In this field, oil is produced from the N oil layer while the gas layer comes from the K layer. Well X was drilled in May 2013 with a target of N oil formation at a depth of 9,007 ft MD, slope (450) and 4-1/2" Liner completion. The initial production of well X was 1,632 BOPD; 5.3 MMSCFD; 0% BSW. Well X is the only well in the Y offshore field that does not penetrate the K gas formation, so gas production from nearby wells is used to produce oil from the N formation. well-to-well gas lift. Along with production time, the reservoir pressure in the N oil layer and K gas layer has decreased, so that oil production in well X has also decreased. With changes in company policy that optimize and increase gas production to increase gas sales to the industry around the company's operational areas since early 2017, the outgoing pressure on the Y platform has increased from 210 psi to 450 psi, causing a total oil well X could not pass through and produce due to high outgoing pressure on platform Y. Well X's last production data was on January 31 2017 with oil production of 179 BOPD and 1.25 MMSCD for gas production and gas lift injection of 0.75 MMSCFD, before finally shutting down. The selection of another artificial lift as a substitute for the gas lift has been carried out to revive well X later. Based on the alloy table made by Weatherford for the selection of artificial lifts for conditions on the Y field platform, ESP has many advantages and appropriate flexibility compared to other types of artificial lifts. The ESP type D1050N which is a mix flow ESP has been selected and after installation in well X in August 2019 it has successfully revived with a production test of 885 BFPD, 681 BOPD, and 23% water content on September 3 2019. ESP in well X has been in production for 2 years, until finally experiencing a leaky tubing problem in September 2021 and requiring a new tubing replacement job along with a new ESP replacement to revive the X well.

Parameter Estimation for a Polymerization Reactor Model with a Composite-Step Trust-Region NLP Algorithm

We consider an application of the trust-region SQP algorithm described by Arora and Biegler (Comput. Optim. Appl., in press) to the parameter estimation for a polymerization reactor. In particular, we are interested in the robustness of this algorithm in solving ill-conditioned optimization problems with differential algebraic (DAE) models. For this system, it is possible to measure a variety of states, such as production and concentrations. Some of these states contain more information and lead to more reliable parameter estimates than would be obtained if the states were not measured. To minimize sensor costs, it is thus beneficial to select the smallest combination of state measurements that contains the most information. Because the polymer process model is nonlinear, we decide to test the information content of measurements by analyzing properties of the reduced Hessian and constructing joint-confidence regions. This approach is related to the observability analysis (Albuquerque, J. S.; Biegler, L. T. AIChE J. 1996, 42, 2841. Narasimhan, S.; Jordache, C. Data Reconciliation and Gross Error Detection; Gulf Publishing Company: Houston, TX, 2000. Crowe, C. M. Chem. Eng. Sci. 1989, 44, 2909). However, for nonlinear problems, a reliable and efficient parameter estimation algorithm is essential for the measurement selection procedure. Finally, whereas inputs to the process are often held constant in parameter estimation problems, these inputs often contain noise. It is therefore necessary to reconcile inputs along with states in a simultaneous optimization framework. This problem becomes an errors in variables model (EVM) and can be considerably larger and more difficult to solve. In this study, we also consider the related EVM problem and compare results to the standard parameter estimation problem.

Limiting criteria of permanent progressive waves

Three parameters to represent wave nonlinearity are derived from the dynamic free surface boundary condition using two different methods. Relationships among the parameters are given for general coordinates including fixed and moving coordinates and for any definition of wave celerity. It is proved that all the proposed parameters become equal to unity at the limiting wave condition. Two relationships among wave variables at the crest of breaking waves are derived. These relationships are exact from a solitary wave to deep water waves. The nonlinearity parameters and limiting wave relationships are examined for special cases, resulting in other famous nonlinearity parameters and breaking conditions. The limiting wave relationships are used to examine the accuracy of breaking waves indices obtained by Yamada and Shiotani [Bull. Disaster Prev. Res. Inst., Kyoto Univ. 18 (1968) 1], Cokelet [Philos. Trans. R. Soc. London, Ser. A 286 (1977) 183] and Dean [Handbook of Coastal and Ocean Engineering, Vol. 1, Gulf Publishing Company, Houston, TX, Chap. 2, pp. 63–94, 1991]. A method for calculating the wave celerity for any fully nonlinear model as a function of water particle velocity and surface elevation is also given.

Globalising Organisations and Empowering People for High Performance Leadership of Our Multicultural World: Or, Behold, The Demise of Business‐as‐usual is at Hand

Reviews, from an anthropological perspective, three 1993 additions to the Gulf Publishing Company's “Managing Cultural Differences” Series. This trilogy is comprised of the volumes Developing the Global Organization: Strategies for Human Resource Professionals, Transcultural Leadership: Empowering the Diverse Workforce, and Multicultural Management: New Skills for Global Success. Examines the five concepts of globalisation, diversity, multiculturalism, transcultural, and empowerment central to the trilogy and to anthropology, and as they are used in both. Views the global paradox — a bigger world economy requires the more powerful smallest of players (e.g., entrepreneurs) — as a useful framework for understanding these and related concepts as they operate in the global village today, and as they may be employed throughout and beyond the 21st century. Finally, reports on: (1) the training, transformation and development tasks of global managers of complexity in business as well as in government, academia, and the military; and, (2) the intercultural learning strategies through which these tasks are achieved and through which these managers, the multicultural workforce and teams they lead, and their organisations are empowered to contribute, collaborate and fully participate in producing their major project: Service, country, group, business, or social structure through the mixture of peoples or technology” (p. 242). This suggests a process, a becoming. In Developing the Global Organization, Robert T. Moran, Philip R. Harris and William G. Stripp continue that globalisation is both a way to think and to act. Specifically, it moves individuals “away from parochialism towards transnationalism”. And it nurtures a state of mind geared toward a more effective use of personal and organisational resources (p. 299).
