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.
