Abstract: L'invention concerne un procédé électromagnétique haute résolution de mise à la terre destiné à éliminer un domaine de fréquence statique. Plusieurs dispositifs d'échantillonnage sont positionnés au niveau d'une zone à explorer et un point à électrode commune pour des points de contrôle adjacents présente la même électrode. Les résultats de l'observation de chaque voie s'étendant dans la même direction sont respectivement disposés de manière conventionnelle pour obtenir une courbe d'observation classique et résoudre une séquence de composante de champ électrique de point topologique et de point topologique de chiffrement. La composante du champ électrique est traitée comme valeur de champ d'observation et une analyse spectrale de la puissance est exécutée et un tenseur d'impédance est estimé. La courbe de changement de distance polaire de la résistance pour le point à fréquence unique du même point d'enregistrement est tracée et la règle de changement de la résistivité est observée et analysée, puis la valeur interférentielle statique de la résistance est éditée puis effacée, et une valeur de résistivité pour le point de fréquence est résolue.

Abstract: The invention relates to a method and means to wind a pipeline in a spiral and thus prepare for storage or for transport to another location, while this pipeline is floating in circles next to each other (as a large spiral) in the water. The considered method only contains the part of laying the pipeline in a spiral in such a way that the spiralling is reproducible and the spiral keeps its round form during its the floating lifetime. After the spiral is unwound the pipeline will come back in its original form. The spiralling starts from a straight stretch of pipeline that will be wound around a central point where anchor lines and centre lines are part of the construction to produce the first winding. When the first winding is prepared it will be kept in place by only centre lines. Steel pipeline is very well to bend when it is in its area of elastic strain. It is possible to calculate at which radius a steel pipeline can be bend, without crossing the boundaries of elasticity. Certainly when one takes the large diameter of the floating circles in consideration the pipeline doesn't come under plastic strain and as a result, it will not deform permanently.

Abstract: A process for treating produced water to generate high pressure steam. Produced water from heavy oil recovery operations is treated by first removing oil and grease. Pretreated produced water is then fed to an evaporator. Up to 95% or more of the pretreated produced water stream is evaporated to produce (1) a distillate having a trace amount of residual solutes therein, and (2) evaporator blowdown containing substantially all solutes from the produced water feed. The distillate may be directly used, or polished to remove the trace residual solutes before being fed to a steam generator. Steam generation in a packaged boiler, such as a water tube boiler having a steam drum and a mud drum with water cooled combustion chamber walls, produces 100% quality high pressure steam for down-hole use.
