摘要： A technique facilitates the treatment of a subterranean formation. The technique involves the use of a fluid delivery system that comprises a continuous feedback system. The continuous feedback system utilizes a real time closed loop interpretation technique to instantaneously synchronize and adjust actions at a well site surface relative to measured downhole events. Sensors are used to monitor at least one downhole property in real time. Based on the real time data, the continuous feedback system enables adjustments to be made with respect to the at least one property in a manner designed to influence a downhole event.

摘要： A method of performing an oilfield operation about a wellbore penetrating a subterranean formation are provided. The method involves performing a fracture operation by generating fractures about the wellbore. The fractures define a hydraulic fracture network (HFN) about the wellbore. The method also involves generating a discrete fracture network (DFN) about the wellbore by extrapolating fracture data from the HFN. The DFN includes fracture branches with intersections therebetween and matrix blocks. The method also involves generating a depth of drainage through the DFN, defining production parameter (s), and performing a production operation to produce fluids from the subterranean formation based on the depth of drainage and the production parameter (s). The production operation may involve generating a flow rate through the DFN, generating a pressure profile of the DFN for an initial time based on the flow rate, and generating a production rate based on the pressure profile.

摘要： A hydraulic fracture design model that simulates the complex physical process of fracture propagation in the earth driven by the injected fluid through a wellbore. An objective in the model is to adhere with the laws of physics governing the surface deformation of the created fracture subjected to the fluid pressure, the fluid flow in the gap formed by the opposing fracture surfaces, the propagation of the fracture front, the transport of the proppant in the fracture carried by the fluid, and the leakoff of the fracturing fluid into the permeable rock. The models used in accordance with methods of the invention are typically based on the assumptions and the mathematical equations for the conventional 2D or P3D models, and further take into account the network of jointed fracture segments. For each fracture segment, the mathematical equations governing the fracture deformation and fluid flow apply. For each time step, the model predicts the incremental growth of the branch tips and the pressure and flow rate distribution in the system by solving the governing equations and satisfying the boundary conditions at the fracture tips, wellbore and connected branch joints. An iterative technique is used to obtain the solution of this highly nonlinear and complex problem.
摘要翻译：一种水力压裂设计模型，模拟通过井筒注入的流体驱动的地球中裂缝扩展的复杂物理过程。该模型的目标是遵循物理学规律，对受到流体压力的产生的裂缝的表面变形进行控制，由相对的断裂面形成的间隙中的流体流动，裂缝前端的传播，在流体中承载的裂缝中的支撑剂，以及压裂液体渗透到可渗透岩石中的泄漏。根据本发明的方法使用的模型通常基于常规2D或P3D模型的假设和数学方程，并且还考虑到连接断裂段的网络。对于每个裂缝段，控制断裂变形和流体流动的数学方程适用。对于每个时间步长，该模型通过求解控制方程并满足裂缝尖端，井筒和连接分支接头处的边界条件来预测分支尖端的增量增长和系统的压力和流量分布。使用迭代技术来获得这种高度非线性和复杂问题的解决方案。
