Application of Simple Smart Logic for Waterflooding Reservoir Management

A simple smart logic for controlling inflow control valves (ICV) in waterflooding reservoir management is implemented and analyzed, with the final objective of improving the long term financial return of a petroleum reservoir. Such a control is based in a reactive simple logic that responds to the watercut measured in the ICV. Basically, when the watercut increases, the ICV is set to close proportionally. For comparison purposes, four strategies are presented: base case scenario with conventional control, the best completion configuration found by trial-and-error, the reactive control, and a deterministic optimal control based on Nonlinear Gradient Method with adjoint-gradient formulation is shown for comparison purposes. Finally, all four strategies are tested again in different reservoir realizations in order to mimic the geological uncertainties. Two different synthetic reservoir models were studied. First, a simple cube with a five-spot well configuration, in which the permeability field has a horizontal pattern defined by lognormal distributions. The second model is a benchmark proposed by the Dutch university, TU delft, with 101 channelized permeability fields representing river patterns. For the first model, no significant relative gain is found neither in the variable control nor in the optimal control. Manly because of the high homogeneity of the reservoir models. Therefore, no intelligent completion is recommended. On the other hand, for the second and more complex case, the results indicate an expressive relative gain in the use of simple reactive logic. Besides, this type of control achieves results nearly as good as the optimal control. The test in different realizations, however, shows that reservoir characterization is still a key part of any attempt to improve production. Although the variable reactive control is semi-independent, with action being taken based on measurements, some parameters need a priori model to be tuned

An unusual localisation of Kaposi's sarcoma: The external auditory canal

The epidemic form of Kaposi's sarcoma is associated with human immunodeficiency virus infection. Cutaneous and mucosal manifestations are frequently reported in the ENT sphere, mostly involving the oral cavity. The external and middle ear are only rarely concerned with only one case of a mastoid lesion within extension to the external auditory canal (EAC) being reported to this day. The present article describes the first case of involvement of the EAC with extension to adjacent structures. This patient presented other Kaposi lesions and had been treated by systemic hormonal therapy. Thereafter local injection of a cytotoxic agent was given without effect. Finally, radiotherapy resulted in a 50% regression of the tumour mass. The epidemiologic factors and therapeutic modalities with their results are described.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Clinical aspects of early and late hypocalcaemia afterthyroid surgery.

This study aimed to evaluate hypocalcaemia (time-course) and need for calcium administration after thyroid surgery in 135 consecutive cases (69 bilateral subtotal thyroidectomies, 50 unilateral lobectomies, 13 total thyroidectomies and three isthmectomies) for benign lesions and for differentiated carcinoma in 89% and 11% respectively.Journal Articleinfo:eu-repo/semantics/publishe

Wide vertical hemipharyngolaryngectomy with immediate glottic and pharyngeal reconstruction using a radial forearm free flap: preliminary results.

We propose a new technique of wide vertical hemipharyngolaryngectomy which combines resection of laterally localized extended pharyngolaryngeal tumors with immediate microsurgical reconstruction using a radial forearm free flap, including the tendon of the palmaris longus. It eliminates the limitations of resections, which are usually performed to avoid closure difficulties of the resulting defect. In addition, the new technique avoids the use of tumor-neighboring structures for closure, fulfilling the oncological principles of surgery performed in this region. Our preliminary results show good restored deglutition and phonation. Postoperative irradiation does not seem to affect these results.Journal ArticleFLWNAinfo:eu-repo/semantics/publishe
