And, if you'd rather trust the final decision to the camera, a ball-in-the-hole scenario is described that'll automatically engage the shutter release when the live view matches your ideal layout.

Normally, when a well begins to flow, the release of pressure cleans up the well bore of contaminants and other debris in the hole during the first few hours it is opened up.
