Compact™ Array Induction, Gamma Ray Tools

Successfully Log Multiple Wells Through Fiberglass Casing, Resolve Earlier Data Uncertainty

Objectives

  • Acquire induction resistivity data through fiberglass casing in three wells to monitor and determine the current oil-water contacts.

Our Approach

  • After collaboration with the operator about the project, Weatherford personnel deployed the induction resistivity-gamma ray tool (MAI-GR) for the evaluation of all the three wells.
  • The induction tool measured the changes in formation resistivity while the gamma ray measurements aided in formation correlation.

Value to Customer

  • The data acquired by Weatherford showed a strong correlation with previously recorded openhole data.
  • The operator successfully achieved time-lapse monitoring of the current oil-water contact across the three wells.
  • Data uncertainty caused by erratic readings in the competitor’s earlier logs were resolved following the Weatherford logging operations.
