摘要： A technique facilitates performance of a perforating operation in a wellbore. The technique comprises positioning a perforating gun assembly downhole in a wellbore via coiled tubing. The perforating gun assembly has a plurality of individually controllable perforating gun sections which may be selectively fired at different well zones. An optical fiber is deployed along the coiled tubing to deliver control signals to the perforating gun assembly. The control signals enable sequential firing of the individually controllable perforating gun sections at the desired locations, e.g. well zones, along the wellbore.

摘要： A perforating gun technique. The technique includes perforating with the gun in a manner that deforms internal support structure thereof. Thus, follow-on treatment with a breakup fluid tailored to the material of the support structure may be utilized to dissolve the structure. The carrier of the gun which houses the structure may then be utilized as a conduit for fluid flow.

摘要： Toolstring topology mapping systems having a downhole toolstring including a master node controller and a plurality of nodes and related methods. The methods involve querying each of the plurality of nodes in the downhole toolstring for actual topology information, receiving actual topology information from each of the plurality of nodes in the downhole toolstring in response to querying, and generating a topology map of the downhole toolstring based on the actual topology information from each of the plurality of nodes in the downhole toolstring. The methods can also involve comparing the topology map with the input topology information to identify topology mismatch and then take remedial actions if needed.

摘要： Methods for measuring air entrainment in a composition comprise providing a rotational blade mixer having a container. A cement slurry containing an air entrainment suppressing agent is prepared in the mixer. The density of the slurry is then measured with a mud balance and compared to a theoretical slurry density calculated from the known weights and volumes of the cement slurry ingredients. The air entrainment suppressing agent comprises a blend of polypropylene glycol and a silicone, or a silicone that is functionalized with ether groups.

摘要： During a drilling operation, measured data from the drilling operation may be received with a panistic inversion and risk estimate module. The panistic inversion and risk estimate module may generate a plurality of mathematical solutions from a panistic inversion that uses the measured data and one or more earth models. The one or more earth models having various parameters may be selected prior to drilling and/or while the drilling operation occurs. For each solution of the plurality of mathematical solutions generated from the panistic inversion, the panistic inversion and risk estimate module may determine if the measured data exceeds one or more probability risk thresholds associated with the drilling operation. If the measured data exceeds the probability risk threshold associated with the drilling operation, then the panistic inversion and risk estimate module may generate an alert.
