The term 'OILFIELD SIGHT' can be broken down into two words: 'WELL' and 'SIGHT'. The word 'WELL' is a four-letter word that refers to an excavation made in the ground for the purpose of extracting water, oil, gas, or other substances. A 'SIGHT' is a view or prospect, usually of a landscape. Therefore, the term 'OILFIELD SIGHT' can be interpreted as a view of an oilfield, which is an area of land where oil is extracted from the ground.
