Locking structure for thermoformed plastic containers for food and other articles wherein the lid and the base of the containers are provided with locking means, specifically a detent and a tab. This technique does not require a radioactive source and in fact it may offer better precision particularly in rugose boreholes. The tubing hanger is landable in the tree bore such that the production tubing is supported in the well by the tree. Once the mark-in video frame is selected, a first audio frame having a first audio frame start time that is at least as early as the first video frame start time is designated as an initial audio frame.
