Over the next decades, up to 25% of the operating budget of east coast CSG to LNG companies will be spent on interventions required to maintain or remediate productivity of the thousands of wells already drilled in Queensland. The cost of each intervention can range between 30% and 50% of the drilling cost of an individual well. Identifying which interventions, also known as workovers, do not contribute to the overall project value can help save the operators millions of dollars over the life of the field. Production of unconventional wells increases initially after workovers and stimulations, but, ultimately, this production declines, often at a rapid rate. Wells are then abandoned after reaching an economical limit. This limit is influenced by multiple factors, some of which can be technical, such as characteristics of the reservoir, or commercial, such as in the price of gas or related to the availability of installed capacity required to process the product. On the basis of a real case study with a CSG to LNG company in Queensland, the present paper will elaborate how one of the operators is making confident decisions around which wells should be included as part of their workover program. Early findings of the study showed that significant value can be created by applying technology in the identification of which areas of the field are most likely to yield a better return and cases where the production decline can be mitigated only by drilling new wells.

Modern IT service provider organizations are under a continuous pressure to increase their competitiveness. Ways to reduce costs while improving performance of services are a key focus area for companies in the IT industry. However, despite all the solutions that have been proposed, modeling and optimizing human-centered processes remains a challenging task. The human operator may be influenced by multiple factors and execute the process in a different way each time, thus introducing a significant variability in the final process outcome. Therefore, the goal of this chapter is to introduce the concept of mashups as an effective approach to improve performance in terms of productivity and reliability of human-centered IT Service Management (ITSM) activities. In particular, this chapter aims to define management solutions required to deliver and demonstrate improvements in performance of human-centered ITSM processes. The introduced management solutions are examined through a real case study, related to the Request Fulfillment process.

This paper presents a real case study to determine the optimal tourist route at Langkawi Island. The Langkawi Island was selected as thecase study because normally, tourist travel to this island will drive the rented car as the primary mode of transport. Thus, the aim of this paper is to develop a mathematical model to find an optimal route for tourist to travel to their interesting places around Langkawi Island. In order to solve the problem, Greedy method was applied in this study and MATLAB version 7.8 has been used to get the solution. The result obtained shows that Nearest Greedy Insertion method gives better result compared to the Nearest Greedy method. The minimum value of the route selection gives effect to the cost of travelling. Therefore, from this study, the best route that connect from one interesting place to others place can be suggested to the tourist as guidance. In addition, tourist can save their time and money to visit all interesting places in this study.

The usual objective when drilling a well is to drill for the lowest overall cost. At first sight, this may seem like a requirement to drill as fast as possible, since many of the costs, such as the rig day rate, wages etc., are time dependent. However, some costs are fixed, for example the cost of the bit, and it may not always be economic to pay a very high cost for a bit that drills somewhat faster, particularly if the other costs are low.In this paper, some first 3465 feet of a reservoir lithology including four bit runs are analyzed so that factors affecting penetration rate are optimized and the lowest possible well cost is achieved. The effects of using other bit types, WOB, RPM and bit hydraulics are simulated in an attempt to determine the optimized parameters, which result in the lowest drilling cost. In this study, reducing both nozzle sizes and mud flow rate, the horse power dissipated at the bit is increased, hence reducing cost per foot of drilled interval. As it is noted, by using this simulator, 17% of the original well cost is saved, which is a considerable amount of money.

Shift to The Front II Komplek Sukamukti Banjaran Project is one of the projects implemented by one of the companies engaged in telecommunications. In its implementation, each project including Shift to The Front II Komplek Sukamukti Banjaran has a time limit specified in the contract. Project scheduling is an important role in predicting both the cost and time in a project. Every project should be able to complete the project before or just in the time specified in the contract. Delay in a project can be anticipated by accelerating the duration of completion by using the crashing method with the application of linear programming. Linear programming will help iteration in the calculation of crashing because if linear programming not used, iteration will be repeated. The objective function in this scheduling is to minimize the cost. This study aims to find a trade-off between the costs and the minimum time expected to complete this project. The acceleration of the duration of this study was carried out using the addition of 4 hours of overtime work, 3 hours of overtime work, 2 hours of overtime work, and 1 hour of overtime work. The normal time for this project is 35 days with a service fee of Rp. 52,335,690. From the results of the crashing analysis, the alternative chosen is to add 1 hour of overtime to 34 days with a total service cost of Rp. 52,375,492. This acceleration will affect the entire project because there are 33 different locations worked on Shift to The Front II and if all these locations can be accelerated then the duration of completion of the entire project will be effective

Abstract A component failure has the potential to significantly impact the cost, manufacturing schedule, and/or the perceived reliability of a system, especially if the root cause of the failure is not known. A failure analysis is often key to mitigating the effects of a componentlevel failure to a customer or a system; minimizing schedule slips, minimizing related accrued costs to the customer, and allowing for the completion of the system with confidence that the reliability of the product had not been compromised. This case study will show how a detailed and systemic failure analysis was able to determine the exact cause of failure of a multiplexer in a high-reliability system, which allowed the manufacturer to confidently proceed with production knowing that the failure was not a systemic issue, but rather that it was a random “one time” event.
