In optimization, a descent direction is a vector 𝐩∈ℝⁿ that, in the sense below, moves us closer towards a local minimum 𝐱* of our objective function f:ℝⁿ→ℝ. Suppose we are computing 𝐱* by an iterative method, such as line search. We define a descent direction 𝐩ₖ∈ℝⁿ at the kth iterate to be any 𝐩ₖ such that 〈𝐩ₖ,∇f(𝐱ₖ)〉<0, where 〈,〉 denotes the inner product. The motivation for such an approach is that small steps along 𝐩ₖ guarantee that f is reduced, by Taylor's theorem.

Method for rapid formation of a stochastic model representative of a heterogeneous underground reservoir, constrained by dynamic data
InactiveUS7200533B2Promote rapid formationElectric/magnetic detection for well-loggingComputation using non-denominational number representationDescent directionDynamic data
A method for rapidly forming a stochastic model of Gaussian or related type, representative of a porous heterogeneous medium such as an underground reservoir, constrained by data characteristic of the displacement of fluids. The method comprises construction of a chain of realizations representative of a stochastic model (Y) by gradually combining an initial realization of (Y) and one or more other realization(s) of (Y) referred to as a composite realization, and minimizing an objective function (J) measuring the difference between a set of non-linear data deduced from the combination by means of a simulator simulating the flow in the medium and the data measured in the medium, by adjustment of the coefficients of the combination. The composite realization results from the projection of the direction of descent of the objective function, calculated by the flow simulator for the initial realization, in the vector subspace generated by P realizations of (Y), randomly drawn and independent of one another, and of the initial realization. During optimization, the chain is explored so as to identify a realization that allows minimizing the objective function (J). In order to sufficiently reduce the objective function, sequentially constructed chains are explored by taking as the initial realization the optimum realization determined for the previous chain. The method may be used for development of oil reservoirs.
