Abstract

Official abstract text for this publication.

A system for cementing a wellbore penetrating an earth formation into which a pipe extends. A cement material is positioned in the space between the wellbore and the pipe by circulated capsules containing the cement material through the pipe into the space between the wellbore and the pipe. The capsules contain the cementing material encapsulated in a shell. The capsules are added to a fluid and the fluid with capsules is circulated through the pipe into the space between the wellbore and the pipe. The shell is breached once the capsules contain the cementing material are in position in the space between the wellbore and the pipe.

First claim

Opening claim text (preview).

The invention claimed is: 1. A composition for use in a cementing process, comprising: a fluid, capsules in said fluid, wherein said capsules have a shell with energetic material embedded in said shell, and a setting material encapsulated in said capsules, wherein a shock wave is capable of releasing said setting material from said capsules in said fluid by disrupting said shell by igniting said energetic material in said shell and releasing said setting material from said capsules so that the setting material sets at a predetermined time. 2. A composition for use in a cementing process of a wellbore penetrating an earth formation into which a conduit extends, said wellbore having a space between the wellbore and the conduit, comprising: a drilling mud, capsules in said mud, wherein said capsules have a shell with energetic material embedded in said shell, and a setting material encapsulated in said capsules, wherein a shock wave is capable of releasing said setting material from said capsules in said mud by disrupting said shell by igniting said energetic material in said shell and releasing said setting material from said capsules so that the setting material is capable of cementing the wellbore.
