When a computer image is generated from a real-world scene having a semi-reflective surface (e.g. window), the computer image will create, at the semi-reflective surface from the viewpoint of the camera, both a reflection of a scene in front of the semi-reflective surface and a transmission of a scene located behind the semi-reflective surface. Similar to a person viewing the real-world scene from different locations, angles, etc., the reflection and transmission may change, and also move relative to each other, as the viewpoint of the camera changes. Unfortunately, the dynamic nature of the reflection and transmission negatively impacts the performance of many computer applications, but performance can generally be improved if the reflection and transmission are separated. The present disclosure uses deep learning to separate reflection and transmission at a semi-reflective surface of a computer image generated from a real-world scene.

A dynamically positioned vessel (DPV) is located above an injection well, inject water or other fluids temporarily or for a short period of time, adjust the injection parameters, and either continue operating for the life of the system or as long as required to add permanent facilities on another platform. The DPV is connected to the potential injection well via a hybrid riser system. The hybrid riser system includes a rigid portion and a flexible portion. Injection using the DPV and the hybrid rise system can be more economical than injection using a conventional mobile offshore drilling unit (MODU) and a rigid riser.
