Abstract

Fremgangsmåter og systemer kan fremskaffes som simulerer et bredt spekter av retningsbestemte brønnhull, inkludert brønnhull med variable hellingsrater og/eller relativt konstante hellingsrater. Fremgangsmåtene og systemene kan også brukes til å simulere utforming av et brønnhull i underjordiske formasjoner som har en kombinasjon av bløte, middels og harde formasjonsmaterialer, multiple lag med formasjonsmaterialer og relativt harde årer plassert blant ett eller flere lag med formasjonsmaterialer. Verdier for borekrone-vandrehastighet fra slike simuleringer kan brukes til å konstruere og/eller velge boreutstyr for bruk ved utforming av et retningsbestemt borehull.
