Herein disclosed are methods and systems related to processes for injection wells generally utilized in the oil and gas industry. More particularly, disclosed herein are methods and systems related to improving the accuracy of profiling and determining individual cumulative fluid injection profiles for an injection period for multiple zones of an injection well in reservoir systems utilizing conventional warmback models. The methods herein allow for proper modeling and allocation of all injection zones, including zones experiencing a cooldown phenomena during shut-in by transforming the cooldown zonal temperature profiles into temperature profiles which can be utilized in a conventional warmback analysis. These methods are particularly useful in mature reservoir systems where the background reference temperature profile is no longer governed by the geothermal reference temperature profile.

Systems and methods for managing equipment in a workspace such as an oil rig are disclosed. Objects are given zones which are physically larger than the objects. A monitoring system is capable of monitoring the objects and the zones for each object. When zones intersect, a collision is possible and the monitoring system can take action to prevent the collision or mitigate damage in the case of a collision. Further, systems and methods for ensuring the moving components are handed-off properly from one support to another are disclosed.

A system for assuring that a rotation brake has engaged on a directional drilling machine. A pump-powered motor drives rotation of a spindle on the machine. The spindle is in turn attached to the above-ground end of a drill string. After the rotation brake is actuated, a controller causes the motor to transmit oppositely-directed rotational pulses to the spindle. If the brake is properly engaged, the pulses will produce spikes in pressure within the hydraulic circuit that powers the pump. When a pressure sensor detects such spikes, it signals the controller and confirms that the brake is engaged.
