Abstract: Methods may include recording pressure and/or temperature data at two or more time points in a region adjacent an isolated zone in a wellbore created by one or more isolation devices; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data. Methods may also include injecting a fluid into an isolated zone in a wellbore created by one or more isolation devices; recording pressure and/or temperature data at two or more time points in a region adjacent the isolated zone; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data.

Abstract: The disclosure pertains to methods for completing a well comprising lowering a coiled-tubing in the well thus forming an annulus between the casing and the coiled-tubing, pumping down said annulus a treatment fluid above the fracturing pressure of the formation while also pumping fluid through the coiled tubing; monitoring in real-time the bottom hole pressure, increasing the pump rate through the coiled-tubing if an increase of bottom hole pressure is observed.

Abstract translation: 本公开涉及完成井的方法，包括降低井中的盘管，从而在壳体和盘管之间形成环形空间，将所述环形空间泵送在地层压裂压力以上的处理流体，同时还泵送流体 连续油管; 实时监测井底压力，如果观察到井底压力增加，则通过螺旋管道提高泵速。
