THE ANALYSIS OF REASONS AND FACTORS AFFECTING THE INITIATION AND DEVELOPMENT OF ACCIDENTS IN DRILLING AND GAS PRODUCTION
Abstract
The paper provides the analysis of possible reasons and factors of accidents initiation. It has been established that one of the main reasons for the initiation of gas showings is the flow of formation fluid into the wellbore due to the fact that formation preesure exceeds bottom hole pressure. It presents the description of the scenarios of possible and the most dangerous accidents, which include jet fire of formation gas outbursts during the loss of pressure of well equipment and the spread of hydrogen sulphide at the release of formation gas without ignition. The probable zones sizes of damaging factors effects for each of the scenarios and the possible number of victims in these scenarios implementation have been determined.
