Performance By The Numbers

Hexa-Combo LWD BHA

Delivered Detailed Reservoir Characterization, Multistage Hydraulic Fracturing Planning, and Optimized Well Placement

Objectives

  • Identify the boundaries of the target zone in order to drill a horizontal section.
  • Obtain data to build an accurate geological model of the drilling zone to perform multistage fracturing operations.

Our Approach

  • Weatherford experts suggested the hexa-combo logging-while-drilling (LWD) bottomhole assembly (BHA), with the distance-to-bed inversion combined with the azimuthal density images, to help locate the target zone boundaries and formation dipping.
  • These services—including deep azimuthal resistivity with boundary mapping inversion, azimuthal sonic, nuclear density, and neutron porosity as well as micro-resistivity imaging—would enable the customer to perform accurate stratigraphic interpretation and ensure proactive well placement, maintaining the well trajectory within planned limits.
  • Micro-resistivity images, recorded while drilling and processed after the tools reached the surface, helped to detect clear geological features, especially fractures and faults, as well as their direction and position.
  • Azimuthal sonic measurements provided information about formation geomechanical properties and stress regime, which gave the basis for the multi-stage fracturing planning.

Value to Customer

  • By using the Weatherford combination of LWD measurements, the operator selected the optimal well path positioning, fractured zones assessment, and fractures type determination.
  • The high-resolution images, delivered while drilling, helped to identify the zones of high production potential and improved reservoir characterization.
  • With the help of the azimuthal density image and bed boundary mapping from resistivity, a precise placement of the well was performed.
  • The addition of the azimuthal sonic measurements provided information for the customer to successfully design a multistage fracturing program.
