What are the main advantages and disadvantages of open hole and cased hole reservoir fluid sampling?
I want to know about the advantages and disadvantages of open hole and cased hole reservoir fluid sampling.
Of course! With open hole sampling, the formation is not sealed off by casing which allows for gathering fluid samples from a larger, unobstructed zone. However, it can be difficult to obtain an accurate sample since the formation can collapse or alter the sample. Conversely, cased hole sampling offers a more secure and reliable sample since the formation is sealed off by casing. But, cased hole sampling may not be able to provide as much information on the surrounding formation as open hole sampling can.
