MWDPlanet’s Wireless Downhole Monitoring Tool Used for Geothermal Plug and Abandonment Operations with Coiled Tubing
Location: New Zealand, Onshore Operator: Western Energy Summary: In geothermal plug and abandonment (P&A) operations, precise downhole temperature monitoring is critical to avoid flash setting of cement. Traditionally, operators have relied on E-Coil (electronic coiled tubing) systems to transmit data from downhole sensors to surface in real time. While effective, these systems involve substantial setup costs, complex reel management, and temperature limitations that make them less ideal for high-heat geothermal environments. To address these challenges, MWDPlanet’s Electromagnetic (EM) Telemetry Technology—originally developed for measurement-while-drilling (MWD) applications—was adapted for coiled tubing use. This case study outlines how EM telemetry was successfully implemented to...
MWDPlanet’s EM Telemetry System Successfully Deployed in a Challenging Anhydrite Rich Area of SE Saskatchewan During Nitrogen Fluid Drilling Operations
Location: SE Saskatchewan, Canada, Northern Portion of the Williston Basin, Onshore Summary: An energy company used MWDPlanet’s EM (Electro-Magnetic) transmitter-based telemetry system to successfully perform nitrogen fluid drilling operations in an anhydrite rich area without the help of an EM signal repeater. This was the first time for the area that an EM system effectively transmitted through the casing and the anhydrite rich formations, providing reliable signals in the lateral sections at the challenging site. Subsequently, MWDPlanet’s EM system was successfully repeatedly deployed for drilling operations in the area.Case Study 1 — Deep HPHT Sidetrack with Geosteering ComplexityLocal to the drilling area energy company presented MWDPlanet with a challenge of supplying an EM system...
Field-Proven Reliability of MWDPlanet’s Technologies in Harsh Drilling Environments in Eastern and Central Ukraine HPHT Gas Reservoirs; Case Studies from Two Wells
Location: Eastern and Central Ukraine, Onshore Operator: Ukrgasvydobuvannya (UGV) Summary: Downhole tools operating in high-pressure, high-temperature (HPHT) and complex wellbore environments face extreme reliability challenges. In two separate drilling campaigns—one in a deep high-temperature sidetrack and another in a high-risk wide-diameter interval—MWDPlanet’s telemetry systems and high-performance battery packs delivered exceptional performance. This paper outlines two case studies, highlighting tool resilience, precision geosteering, and operational efficiency achieved using this equipment.Case Study 1 — Deep HPHT Sidetrack with Geosteering Complexity Well Type: Directional / Sidetrack Kick-off Point (KOP): 5,480 m Total Depth: >5,000 m Hole Size: 146.05 mm Mud Weight:...
