WELL INSTRUMENTATION DEPLOYMENT PAST A DOWNHOLE TOOL FOR IN SITU HYDROCARBON RECOVERY OPERATIONS

摘要

A transition device for deploying instrumentation below a downhole tool, such as a downhole pump, employed in hydrocarbon recovery operations can include a housing serially connectable between the downhole tool and a guide string insertable into the well ahead of the downhole tool. The transition device can also include a sealable crossover channel extending through the housing and having a proximal and a distal end, the crossover channel providing a crossover path for at least one instrumentation line between an exterior of the transition device at the proximal end and an interior of the guide string at the distal end. The fluid channel can extend through the housing and be radially offset from and capable of establishing fluid communication with the crossover channel, the fluid channel being configured to provide a pressurized fluid into the crossover channel to propel the at least one instrumentation line forward inside the guide string.

主权项

1. An assembly for use in hydrocarbon recovery operations along a well, comprising:
a downhole tool deployed into the well; a guide string deployed into the well ahead of the downhole tool; at least one instrumentation line deployed into the well inside the guide string; and a transition device serially connected between the downhole tool and the guide string, comprising a housing and a crossover channel extending through the housing and having a proximal end and a distal end, the crossover channel providing a crossover path for the at least one instrumentation line between an exterior of the transition device at the proximal end and an interior of the guide string at the distal end.
