Matrix acidizing of two Khuff bilateral horizontal gas wells was performed using fiber optic enabled coiled tubing (FOECT) distributed temperature surveys (DTS) to optimize acid coverage and well productivity. Cleanout and stimulation of each wellbore was facilitated with a 2 7/8 in. high-pressure jetting tool. Lateral access and lateral confirmation was enabled using the multilateral selective reenter tool and real time DTS measurements. In each well, placement of the main treating fluid, i.e., HCl, was modified real time based on the temperature response observed with DTS profiles. Treatment fluid loss to the lateral window/junction or to the toe could be confirmed with downhole measurements and controlled with real time modifications of the treatment fluid pumping schedule. DTS profiles, after each of the modified acid treatment stages, indicated significant incremental improvements towards uniform fluid placement, compared to the pre-stimulation preflush injection profiles. Post flush evaluation in each lateral confirmed diversion efficiency of the chemical diverter. Downhole FOECT data supported by real time interpretation during key stages of the treatment resolved the uncertainties associated with conventional acid stimulation of multilateral open hole carbonate wells, and enabled proper control of CT stimulation jobs. Optimum acid coverage of target zones was achieved. Source

This paper deals with a recent approach that tackles the product and the supply chain design issues at the same time. The simultaneous design of a product and its supply chain is relevant. In fact, supply chain decisions incorporated during the early phases of the product design enhance its performance. Therefore, collaboration among all supply chain partners is very important, especially at the product design phase. In this paper, we investigate the role of the PLM (Product Life Cycle Management) as a key to integrating product and supply chain optimization. We study the case of an existing product's redesign. The design change affects either the components or the process of the product or both of them at once. First, we present an UML model for designing the product and its supply chain integrating PLM. Then, we propose a mixed integer linear programming (MILP) formulation to determine simultaneously the optimal redesign alternative accompanied with its optimal upstream supply chain configuration. Being at a strategic design, time periods in the mathematical model are considered to be product life cycle phases. This consideration gave a dynamic aspect to the model. Finally a numerical example is given to illustrate the application of the model. © 2015 International Institute for Innovation, Industrial Engineering and Entrepreneurship - I4e2. Source
