摘要:... When producing CBM, the working level within a CBM wellbore annulus needs to be monitored to dynamically adjust the gas drainage and extraction processes. However, the existing method of measuring the working level does not meet the needs of accurate adjustment, so we des...

摘要:Abstract(#br)Controlling cement shrinkage in a wellbore is important in maintaining its integrity. Although numerous laboratory experiments on the water absorption and shrinkage behaviour of oil well cement have been reported in the past, such behaviour in the wellbore annulus...

摘要:Abstract(#br)The sustained casing pressure (SCP) threatens the wellbore safety significantly. Generally, the effects of factors that cause casing pressure cannot be quantified. Some vague terms are often used to describe the risk degree. Considering the serious SCP situation in X...

摘要:... If enough buildups of surface casing pressure (SCP) and rates of surface casing vent flow (SCVF) recorded on intermediate wellbore casing strings are available, a frequency distribution of leakage path permeability values can be obtained. Uncertainty about the location of the...
