Q3. In a water flood operation in reservoir A, water is being distributed to severalinjection wells from a common injection system; that is, water is supplied to all thewells at approximately the same well head pressure. Routine measurement of theindividual well injection rates by the team of field operators showed that one well wasreceiving approximately 45% more than its neighbours. The sum of the kh productsfor all of the injection wells were approximately the same depth. As a member of theteam, explain:What are the possible causes of the abnormally high injection rate in this well, andwhat production logs or other tests might be run to further diagnose the problem andplan remedial action?

Question

Q3. In a water flood operation in reservoir A, water is being distributed to several
injection wells from a common injection system; that is, water is supplied to all the
wells at approximately the same well head pressure. Routine measurement of the
individual well injection rates by the team of field operators showed that one well was
receiving approximately 45% more than its neighbours. The sum of the kh products
for all of the injection wells were approximately the same depth. As a member of the
team, explain:
What are the possible causes of the abnormally high injection rate in this well, and
what production logs or other tests might be run to further diagnose the problem and
plan remedial action?
