Wellbore Surveying

Wellbore surveys provide definitive data that depict the position of a borehole or well path in three-dimensional space. Sperry Drilling services' wellbore surveying service delivers a comprehensive well positioning approach, generating the necessary risk versus reward analysis and survey program. Sperry can also help ensure survey executions per expectations and provide a one-stop shop for well position information.

  • Early analysis of well position requirements
  • Evaluation of risk versus reward and creation of a survey program
  • Help ensure wellbore construction surveys meet operator and well position expectations
  • Capture of lessons learned regarding wellbore placement
  • Load wellbore data into definitive database
  • Reporting and distribution of final survey

Directional Sensors
When drilling vertical, horizontal, or extended reach wells, obtaining accurate measurements of inclination and azimuth is a fundamental requirement. For these measurements, Sperry Drilling services offers three types of MWD directional sensors and the Evader® MWD gyro service.
Evader® Gyro-While-Drilling Service
Aids in orienting and steering the drillstring. Improves wellbore guidance to avoid collision with other wells on multi-well platforms. Immune to magnetic interference.
Radian® Azimuthal Gamma Ray and Inclination Service
The Radian® azimuthal gamma ray and inclination service provides high-quality borehole images for geosteering, and precise gamma-ray measurements for reservoir evaluation.
