Questions and Answers

1.

What is a phenomenon encountered during dry forward combustion in which an oil zone around the production well cannot be pushed forward by the heated oil ?

Explanation
Liquid blocking is a phenomenon encountered during dry forward combustion in which an oil zone around the production well cannot be pushed forward by the heated oil. This occurs when there is a high viscosity or low permeability of the oil, preventing it from flowing and being pushed forward by the heat. As a result, the oil zone remains stagnant, leading to decreased production and inefficient recovery of oil.

In the past, engineers usually design muds having bigger density than the formation, but sometimes this yields a mud cake that is excessively thick, causing problems in the cementing. Nowadays, they have invented a new method to use a lighter mud, let kicks occur, and deploy RBOP to drill and circulate the kicks. What is the name of this drilling method?

Explanation
The drilling method described in the passage is underbalanced drilling. In the past, engineers used muds with higher density than the formation, which resulted in a thick mud cake that caused issues with cementing. However, with the invention of underbalanced drilling, engineers now use a lighter mud, allow kicks to occur, and utilize a rotating blowout preventer (RBOP) to drill and circulate the kicks. This method helps to prevent the formation of a thick mud cake and improves the overall drilling process.
