Abstract: Wellhead system, assembly and method monitors landing or retrieving of wellhead component at pre-determined landed position in main bore of wellhead member of wellhead. System includes running tool, instrument spool and sensor assembly. Running tool couples to wellhead component, lands or retrieves wellhead component within main bore of wellhead member, decouples from wellhead component, and has passive triggering device disposed in or on running tool. Instrument spool is pressure-containing, connects within wellhead at location above landed position of wellhead component, forms bore to align with main bore of wellhead, provides clearance for the wellhead component and running tool to be run therethrough, and has vertical height dimension such that, in pre-determined landed position, passive triggering device is located in bore of instrument spool.

Abstract: A method and fluid connection system to fluidly connect a fracturing manifold to a fracturing tree. The method includes fluidly connecting a plurality of flexible flowlines between the manifold outlet of a fracturing manifold module and the fracturing tree such that fluid from the manifold outlet is distributed into the flexible flowlines and into the fracturing tree to avoid abrupt or right angle changes in direction in all fluid connections at the fracturing tree and between the manifold outlet and the fracturing tree. The fluid connection system includes a flow distribution block having a single inlet and a plurality of outlets, and distributes fluid flow between the single inlet and the plurality of outlets without abrupt or right angle changes in direction. The flexible flowlines have a first end fluidly connected to one of the plurality of outlets, and a second end fluidly connected to the fracturing tree.
