The inner tubular member may include a flow control device configured to allow fluid to pass radially between the inner bore and the annulus. | 06-19-2014 |
20140174714 | COMPLETION SYSTEM HAVING A SAND CONTROL ASSEMBLY, AN INDUCTIVE COUPLER, AND A SENSOR PROXIMATE TO THE SAND CONTROL ASSEMBLY - A completion system for use in a well includes a first completion section and a second section. The first completion section has a sand control assembly to prevent passage of particulates, a first inductive coupler portion, and a sensor positioned proximate to the sand control assembly that is electrically coupled to the first inductive coupler portion. The second section is deployable after installation of the first completion section. It includes a second inductive coupler portion to communicate with the first inductive coupler portion, to enable communication between the first completion section's sensor and another component coupled to the second section. | 06-26-2014 |
20140209327 | SINGLE TRIP COMPLETION SYSTEM AND METHOD - A method includes in a single trip running a completion system having an internal bore into a wellbore that penetrates a formation zone, the completion system having an upper completion connected to a lower completion, setting an isolation packer forming a barrier above the formation zone, displacing the annulus fluid above the set isolation packer and then setting an upper packer thereby providing a completion barrier above the set isolation packer. The annulus fluid may be displaced prior to setting an upper completion packer. | 07-31-2014 |
