Measurement-While-Drilling (MWD)

Halliburton utilizes measurement-while-drilling (MWD) surveying technology to determine the well path and its position in three-dimensional space. MWD is a valuable tool that can establish true vertical depth, bottom-hole location, and orientation of directional drilling systems.

A range of measurements of the drillstring, BHA and wellbore properties are available to ensure the drilling is occurring according to plan and to identify conditions that could lead to equipment damage or other non-productive time events. These measurements provide information on:

  • The forces acting on the drillstring and BHA including dynamic behavior and the occurrence of vibration
  • The static and dynamic pressures internally within the drillstring and the annulus
  • The size and shape of the wellbore itself

Sperry Drilling services leads the industry with the largest and most robust high pressure, high temperature offering, and invests in significant research and development in HP/HT technology. In HP or HT wells, equipment is required to withstand temperatures higher than 300°F/149°C and pressures above 18,000 psi/124 MPa. Today, the majority of Sperry Drilling's measurement/logging-while-drilling (M/LWD) tools are rated to 347°F/175° C and 25,000 psi/172 MPa.
