Openhole Logging

Overview

The Openhole Logging tools from WellRay provide logging engineers with an intuitive operating environment and a reliable quality control process. It relies on advanced combined physical survey detectors to accurately measure and acquire geophysical, petrophysical and geomechanical data of downhole reservoirs, and restores the measured data to the real characteristic parameters of downhole reservoirs through rigorous mathematical equations. It provides reliable data for geological analysts to gain insight into the true characteristics of the reservoir framework and fluids. It can also measure and capture multiple downhole engineering parameters (diameter, inclination, orientation, downhole temperature, mud density, resistivity, etc.) to provide drilling engineers with an intuitive understanding of downhole engineering status and help customers make more informed drilling, completion, and production decisions.

Key Objectives

Evaluate reservoir potential (hydrocarbon saturation, porosity, permeability).
Identify lithology (rock type) and fluid types (oil, gas, water).
Guide decisions on well completion (perforation zones, casing placement).
Assess geomechanical properties (wellbore stability, stress orientation).
Detect natural fractures or faults for enhanced recovery strategies.

Applications Scenarios

Reservoir Characterization: Locate pay zones and estimate reserves.
Wellbore Stability: Predict collapse risks in shales or weak formations.
Completion Design: Optimize perforation intervals and sand control.
Geosteering: Guide drilling in real-time using Logging While Drilling (LWD).

Modern Innovations

LWD (Logging While Drilling): Real-time data reduces post-drilling logging risks.
AI-Driven Interpretation: Machine learning accelerates log analysis for faster insights.
High-Resolution Sensors: Advanced imaging tools reveal micro-scale fractures and textures.
LWT (Logging While Tripping): Advanced imaging tools reveal micro-scale fractures and textures.
