Abstract: A method is described for estimating either flowback or the reservoir fluids production rate from either one individual inlet or the contribution from several inlets separated by intervals in a wellbore located in an oil and/or gas reservoir. The wellbore may include a casing with a plurality of magnetic irregularity elements, such as casing collars, to generate magnetic perturbations within the casing. In the method, one or more sensor elements are delivered in such a way that the flow drags them while the sensor elements record in time the magnetic perturbations generated by the magnetic irregularity elements. The known location of the magnetic irregularity elements and the reading of perturbations enables estimating the velocity of the sensor element(s) along the path direction of the casing, to determine the velocity of the fluid.

Abstract: The present invention relates to a method of estimating the region of damage due to collapse in the wall of a well during the drilling operation, normally using drilling fluid, where said well can, for example, be intended either for the injection or else for the production of a gas or oil reservoir. Other uses can be found in mining and in civil engineering work. This method is characterized by a set of analytical steps that allow establishing, for example, optimal drilling parameters so as to allow the fastest possible drilling speed that is also safe enough to allow is charging the collapse material without jamming the drilling tool. This method likewise allows assessing both the width and depth of damage in the wall of the well.

The method further includes determining potential drilling locations for the second new well, determining the drilling location for the first new well based at least in part on the determined potential drilling locations for the second new well, and outputting the drilling plan comprising the determined drilling location for the first new well and the determined potential drilling locations for the second new well.

Abstract: The present invention is related to a method for estimating the fractured volume in a reservoir domain, said fractured volume generated by injecting a high pressure fluid into the reservoir domain. The high pressure fluid generates new fractures allowing a more effective drainage of porous rocks, generally identified as geological material, containing oil or gas. As a result, the effective reservoir volume increases. According to embodiments of the invention, the method provides a dynamic estimation of the fractured volume taking into account the evolution of the rock and the fractures. In other embodiment, the evolution of the fractured volume is estimated by generating an envelope surrounding the induced fractures allowing a better estimation of the fractured volume.
