Development and Application of a 3D-Wellbore Visualization System for Hydraulics Analyses

Abstract

fax 01-972-952-9435.Abstract Visualization technology has evolved into an important G&G tool to view and interpret seismic data, 3D logs, geocellular models, grids, horizons, and well placements. Directional drillers also benefit from visualizing complex placements in 3D; however, this is one of very few drilling applications that currently exists for this technology. I ntroduced in this paper is software that for the first time permits interactive 3D visualization of the inside of a virtual wellbore. I n this initial offering, downhole drilling hydraulics and related conditions can be critically examined while navigating the well from surface to TD using a standard PC and a j oystick. The new software system has application for interpreting large data sets, mitigating drilling problems, training, and encouraging collaboration among multi-disciplinary teams.Stunning 3D perspective rendering can show internal and side proj ections of well tortuosity, cuttings beds, drill string ( including eccentricity) , annular velocity profiles, formations ( texture, rugosity, and breakout) , downhole engineering parameters ( temperature, ESDs, etc.) , and downhole tools, among others. " I ntelligence" is incorporated that can direct the software to automatically find, display, and visually inspect anomalies and potential hydraulics-related problems. Simulated data are provided by an advanced hydraulics program; a real-time version is planned that also will include other key drilling and wellbore parameters. Both options are suitable for use in real-time drilling centers.The purpose of this paper is to discuss the development, application, and opportunities of this wellbore visualization software. Special emphasis is placed on the quality and uncertainty of models, and methods used to drive the 3D graphics. The design, development, and implementation of the fit-for-purpose graphics platform also are discussed.

Challenges of Modeling Drilling Systems For the Purposes of Automation and Control
