Abstract
Methods determine a state of a well and comprise: receiving a set of well operations data comprising at least some measured well operations data; determining the occurrence of a well operations event based on the received data; evaluating one or more possible state transitions from a current well operations state to one or more possible new well operations states, the current state and the possible new states selected from a configurable plurality of well operations states, wherein evaluating the one or more possible state transitions is based on the current state, the determined event and the received data and wherein evaluating the one or more possible state transitions comprises determining a confidence level associated with each of the possible new states; and determining one of the possible new states to be a new predicted well operations state according to whichever possible new state has a highest confidence level.
