Abstract: A production assembly includes a tree body, in which the tree body includes a main production bore formed about an axis and a wing bore extending through the tree body from the main production bore. The tree body may further include a wing valve in fluid communication with the wing bore to control the flow of fluid through the wing bore, in which at least a portion of the wing bore is angled from perpendicular with respect to the axis of the main production bore.

Abstract: An apparatus and method that uses the local raw water injection equipment to use the minimally processed seawater as the hydraulic power fluid for the downhole turbine/pump arrangement. In one embodiment, the raw water provides the hydraulic power to the downhole equipment via the production well annulus in an open loop arrangement. The raw water is co-mingled with the production fluids. In another embodiment, the raw water provides the hydraulic power to the downhole equipment via the production well annulus in a closed loop arrangement. The raw water is not co-mingled with the production fluids. In another embodiment, the raw water provides hydraulic power to the downhole equipment via the production well annulus in an open loop downhole arrangement. The raw water discharged from the turbine is conveyed to a suitable formation for injection via a dual completion well.

Abstract: A production riser that provides the benefits of a slug catcher, riser based gas lift, and multiphase meter in a single device and is suited to both shallow and deep-water oil/gas field developments. The riser is formed from a pipe within a pipe. The inner pipe provides the path for the production fluids. Perforations are provided near the base and top of the inner pipe. The top of the annulus between the pipes is closed and is in fluid communication with a gas supply/compression system via an isolation control valve/choke. The bottom of the annulus is closed. Three sets of pressure and temperature transducer transmitters are installed at the top, center, and base of the riser through the outer pipe wall.
