Case Study: EC-Drill® World first Managed Pressure OHGP

Horizontal open holes in an unconsolidated sand reservoir with low Pressure Fracture Gradient margin, proved challenging for this major operator in deepwater, Gulf of Mexico (GOM).  Find out how the World's First Managed Pressure Horizontal Open Hole Gravel Pack (OPHG) project was achieved with EC-Drill®.


  • CHALLENGE: Horizontal open holes in an unconsolidated sand reservoir

  • SOLUTION:  EC-Drill® Controlled Mud Level (CML) was identified as the technology that could best handle the gravel packing, drilling, casing, and cementing in the narrow pore pressure and fracture gradient margin

  • RESULTS: The operator successfully executed four horizontal open hole gravel packs in a very challenging reservoir. These were the world’s first Managed Pressure Gravel Pack operations with EC-Drill®.
