  • Publication number: 20140365420
    Abstract: A computer-implemented method for determining elastic properties for a heterogeneous anisotropic geological formation is described herein. The method includes grouping sonic velocity data from a borehole section (or borehole sections) into a number of clusters (e.g., one or more clusters). The sonic velocity data is grouped into clusters using petrophysical log data from the borehole section. The method also includes inverting the sonic velocity data for the clusters to determine elastic properties for each cluster. In some cases, the elastic properties for the clusters are combined to determine a relationship between the elastic properties and formation heterogeneity.

  • Publication number: 20140299315
    Abstract: A system and method is provided for performing stimulation operations at a wellsite having a subterranean formation with a reservoir therein. The method involves acquiring integrated wellsite data (e.g., geomechanical, geological, and/or geophysical properties of the formation, and/or geometrical properties of the mechanical discontinuities in the formation). The method also involves generating a mechanical earth model using the integrated wellsite data, and identifying a crossing behavior between an induced hydraulic fracture and at least one discontinuity in the formation. The method also involves optimizing a stimulation plan to achieve an optimized crossing behavior. The stimulation plan includes at least one of fluid viscosity, rate of injection of the fracturing fluid, and concentration of a fluid loss additive. The optimization may further include adjusting the stimulation plan to achieve the optimized crossing behavior between the induced hydraulic fracture and the discontinuity in the formation.

  • Patent number: 8222581
    Abstract: A process of using finite element analysis for determining the behavior of a system, submitted to predetermined load and displacement boundary conditions with a degree of freedom relative to a local coordinate system released at one system node. For a geometrically non-linear solution scheme, a plurality of incremental steps are carried, for which computing for a finite element of the system a displacement vector at the nodes of the finite element is performed by minimizing the energy of the system. For a geometrically linear solution scheme, a single solving step is carried. The step of minimizing is carried out, for a node having a released degree of freedom, in a local frame of reference, and the released degree of freedom at the node is expressed along one axis of such frame. Hybrid reference frames allow expressing and considering in the formulation the constraints of the non-released degrees of freedom simply.

  • Patent number: 7785108
    Abstract: A denture attachment system includes an implant member adapted to be secured in a mandible such that a head of the implant member projects out of the mandible. A locking mechanism is adapted to be received in a denture so as to cooperate with the implant member to releasably secure the denture to the implant member. The locking mechanism has a receptacle for receiving the head of the implant member. A locking member is movable between a locking position in which the locking member blocks an access out of the receptacle by opposing a surface complementary to the shape of the head of the implant member to hold the implant member captive in the receptacle with points of contact between the head of the implant member and the locking member being diametrically opposed with respect to the head, and a release position in which the head of the implant member may enter/exit the receptacle).

  • Publication number: 20100157737
    Abstract: Methods and related systems are described for measuring acoustic signals in a borehole during a fracturing operation. The system includes a downhole toolstring designed and adapted for deployment in a borehole formed within a subterranean rock formation. A downhole rock fracturing tool opens and propagates a fracture in the subterranean rock formation. Dipole and/or quadrupole acoustic sources transmit acoustic energy into the subterranean rock formation. A receiver array measures acoustic energy traveling through the subterranean rock formation before, during and after the fracture induction. Geophones mounted on extendable arms can be used to measure shear wave acoustic energy travelling in the rock formation. The toolstring can be constructed such that the sources and receivers straddle the fracture zone during the fracturing.

  • Patent number: 7587303
    Abstract: For determining the behavior of a flexible system submitted to predetermined displacement boundary conditions, a process uses geometrically non-linear finite element analysis. The process has a plurality of incremental steps within a total Lagrangian formalism with co-rotational update. In each incremental step, one computes for a finite element of the flexible system a displacement vector, having translational and rotational components, at the nodes of the finite element. This computation of the displacement vector is carried out by minimizing the energy of the flexible system when the system is submitted to a fraction of the predetermined displacement. For a given finite element, the co-rotational update is carried out by computing an updated elementary frame of reference, without considering the bending rotational components of the displacement vectors computed at the nodes of the finite element. The properties of this co-rotational update make all computations similar, hence simpler and easier.

  • Patent number: 7499845
    Abstract: Analyzing the mechanical state of an assembly modeled by a computer aided design system includes generating a model of a fastener and a part of the assembly. The fastener model includes an engaging region and the part model includes a receiving region to fastenably receive the engaging region. The fastener and the part are each represented by finite element representations that include elastically interconnected nodes. A tightening mesh interconnecting nodes of the engaging region and nodes of the receiving region is generated and a force applied between the nodes of the engaging and receiving region is determined based on a pre-tension force occurring upon engaging the engaging region with the receiving region.
