Well Relief, Intersection and Ranging
Reduce risk, increase safety, and maximize efficiency
K&M uses science-based engineering approaches to plan and execute wells requiring interception and ranging, including relief and plug and abandon operations, to reduce risk, increase safety, and maximize efficiency. Used for both onshore and offshore drilling projects, these services can improve ROP and tripping time while minimizing geological risks to construct the well as fast as possible.
Phase 1: Planning
A well is planned to enable completing it in the shortest time practicable with minimal risk of failure, while ensuring the safety of personnel. K&M performs a detailed feasibility study of the relief well construction design and program, including:
Phase 2: Locating and Following Target
This phase locates the relative position of the relief well to the target well using proven, fit-for-purpose ranging technologies to reduce well construction time and HSE risks. K&M provides recommendations and access to the latest ranging technologies while managing anticollision risks of premature, unplanned interception. Current ranging technologies include:
Phase 3: Approaching Target
Phase 3 is directional drilling toa point that converges near the blowing well’s casing, BHA. or any target offset well to intersect. within the detection distance of the ranging technologies. K&M Technology Group’s services in this phase deliver optimized drilling operations to ensure faster relief-well execution and the most accurate wellbore trajectory to save on sidetrack runs.
Phase 4: lntercepting Target
The interception phase starts after installing the last casing to minimize the open hole exposure before intercepting the target well. This is followed by drilling to intercept the blowout well and gain hydraulic communication to perform kill operations. K&M plans and monitors the incidence angle and high side to the target well at the intercept point to recommend the required dogleg severity, anticipates any blowout well-positioning issue, and supervises the directional drilling toward the target well to the intercept point.
Phase 5: Dynamic Well-Killing Operations
The well-killing operation phase establishes communication between the relief well and the target well by hydraulic communication, milling, or perforating. lf required, kill mud is pumped into the target well to stop any flow from the reservoir. K&M aids in the dynamic modeling of hydraulics to confirm the dynamic kill parameters.
