..., and hyperbolic b-values are in the range of 0 to 1. However, most of the production data from tight gas reservoirs is in the transient flow regime and not in the BDF regime. This results in values of b bigger than 1, and a forecast which can significantly over-predict the reserves. The recently developed "power...

... data to identify trends enhances the flow simulation understanding. Introduction The paper's objective is to gain preliminary understanding of communication amongst wells, using only production data and translate that communication knowledge into geology and reservoir engineering concepts...

... Abstract In this paper, a novel technique has been developed to implicitly estimate the relative permeability by history matching three-phase production data with the ensemble Kalman filter (EnKF). Power law repetitive of the relative permeability curves is utilized, while both endpoints...

... Abstract Analysis of production data for characterization of reservoirs is becoming more popular. Sophisticated tools and methodologies exist to extract permeability, completion effectiveness and pore volume from production data (rates and flowing pressures). Often, in practice...

... the EnKF technique, both the static and dynamic parameters of the reservoir model can be continuously updated by assimilating the measured production data. However, the updated static parameters of the entire reservoir are often found to be inconsistent with the geostatistical simulated results at each...

... that would lead to determining the minimum injection water leading to maximum oil recovery. This paper presents application of neural network for analyzing data from a Canadian oil field that has been under waterflooding for several years. At first, production data for the last 20 years were obtained...

... case is an infill SAGD project with two planned SAGD well pairs and eight existing primary production wells which have 5-years of primary production. A bottom water zone is also present. Three major steps of the workflow are (1) history matching primary production data, (2) optimizing SAGD performance...

... type curves are effective tools for analyzing production data. Through integration of flowing pressure and rate data, the modern production decline analysis can be used to estimate Original Gas-in-Place (OGIP, G i ), formation flow capacity ( kh ), fracture length or fracture conductivity. Modern...

... Abstract This paper presents a procedure to estimate relative permeability curves together with gridblock porosities and permeabilities by automatic history matching three-phase flow production data using the LBFGS algorithm for optimization and the adjoint method for generating sensitivity...

... Abstract Even though production data have direct responses of reservoir heterogeneity and connectivity, they are rarely incorporated into reservoir modeling workflow among the geological community. In this paper, an experiment-designed, flow-based ranking method is proposed to mitigate...
