Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A finite-difference numerical method for solving the model represented by the Poisson equation with integral non-local boundary conditions is considered. The model describes the steady flow of fluid near the well under the condition of a known total flow both on the well contour and on the permeable part of the domain boundary. The model describes one of the possible situations in well-logged oil production. The problems of existence and uniqueness of the solution to this problem are discussed. Peaceman–Rachford type method used to construct a difference scheme.
