Drilling
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.
The company’s new Retina imaging system creates high-resolution borehole images at the drill bit.

Altitude Energy Partners optimized drilling efficiency by minimizing dysfunctions and protecting downhole components. Their directional drilling team ensured consistent curves and laterals through precise BHA design, modeling, and trajectory control—reducing nonproductive time and drilling costs, and achieving a 100% improvement in efficiency by pad completion.

Managed-pressure drilling has been associated as a technology used only on problematic wells and only as a last resort. However, when integrated at the beginning of operations as part of a comprehensive well plan, it becomes a performance-enhancing solution for any type of well classification, including development, directional, multilaterals, and horizontals. -
This paper describes a successful U-turn trajectory test in South Texas that has created new economic project opportunities for the company and increased optionality within challenged lease spaces across the field.
