Elliptical-Circular Hole System
An elliptical-circular hole system, or ECHS, is a type of specialized drilling platform used to access difficult-to-reach areas in the oil and gas industry. Such systems are typically used in ultra-deepwater drilling applications, where traditional means of accessing a target are not feasible due to the extreme high pressure and temperature found in such depths.
An ECHS uses an elliptical-shaped hole for drilling. This hole is constantly being caused by a special rotary drill, resulting in a specific directional rotation and end-section cut-off, which allows the drill bit to maintain a high level of maneuvrability as it advances through difficult terrain. The hole will also include arc-shaped cutters which are strategically positioned throughout the hole in order to streamline the drilling process.
The ECHS system also contains a series of interconnected pressurised fluids, pipes and valves that enable the targeted area to be accessed at a safe and uniform rate. This is because fluid and air pressure can be regulated with precision to ensure that drilling can occur at a safe speed, while also being adequately protected against hazards and unexpected events.
The elliptical-circular hole system is also capable of providing highly accurate drill trajectories. This is achieved through a combination of state of the art GPS systems, digital camera systems, motion software and digital 3D drilling systems. The technology is so advanced that all parameters can be adjusted through computer software in order to obtain the highest accuracy.
While using an elliptical-circular hole system is often more expensive than convention drilling methods, the improved safety and operational efficiency makes it the ideal solution for difficult-to-reach areas in oil and gas drilling operations. Its also an ideal system for drilling in areas where traditional drilling technology might be impractical, as the system uses a tilted elliptical hole rather than a straight line cut.
Overall, an elliptical-circular hole system is a highly advanced and specialized piece of engineering that can be used to access difficult-to-reach areas of oil and gas operations. Its a cost-efficient and reliable solution for drilling in ultra-deepwater areas, and can provide a higher degree of safety, precision and control than standard drilling equipment.
