Transient temperature behavior and analysis of single-phase liquid-water geothermal reservoirs during drawdown and buildup tests: Part I. Theory, new analytical and approximate solutions

TL;DR: In this paper, analytical and approximate solutions are presented for predicting drawdown and buildup sand-face transient temperature behaviors of a fully penetrating vertical well in an infinite-acting homogeneous reservoir.

A Coupled Transient Wellbore/Reservoir-Temperature Analytical Model

TL;DR: In this article, a coupled transient wellbore/reservoir thermal analytical model, consisting of a combined reservoir/casing/tubing system, is presented, which considers flow of a slightly compressible, single-phase fluid in a homogeneous infiniteacting reservoir system and provides temperature-transient data for drawdown and buildup tests at any gauge location along the well-bore.

The Ensemble Kalman Filter: theoretical formulation and practical implementation

TL;DR: A fairly extensive discussion is devoted to the use of time correlated model errors and the estimation of model bias, and an ensemble based optimal interpolation scheme is presented as a cost-effective approach which may serve as an alternative to the EnKF in some applications.

Inverse Problem Theory: Methods for Data Fitting and Model Parameter Estimation

TL;DR: In this paper, the least-squares (l 2 -norm) and the Minimax (l #-norm) Criterion are introduced. But they do not cover the general discrete inverse problem.

Estimation of Aquifer Parameters Under Transient and Steady State Conditions: 1. Maximum Likelihood Method Incorporating Prior Information

TL;DR: In this article, a method is presented to estimate the parameters of groundwater flow models under steady and nonsteady state conditions, including the initial head distribution, which can also be estimated if the system is originally at a steady state.

Quasi‐Linear Geostatistical Theory for Inversing

TL;DR: In this paper, a quasi-linear theory is presented for the geostatistical solution to the inverse problem, where the unknown is parameterized as a realization of a random field, and the estimation problem is solved in two phases: structural analysis where the random field is characterized, followed by estimation of the log transmissivity conditional on all observations.
