Consider a well in which the annulus is full of 11.5 ppg fluid and the tubing is full of 7 ppg fluid. What should be done to reverse circulate the well with 11.5 ppg while maintaining the bottom hole pressure constant?

• A. Hold tubing pressure constant while circulating
• B. Hold the pressure inside the packer constant
• C. Hold casing pressure constant while reverse circulate
• D. Hole casing pressure constant until one tubing volume is reached and then hold tubing pressure constant
