Open Hole Services
Reliable, high-resolution formation evaluation. A Wireline Division of Tucker Energy Services Ltd.
Overview
Tucker Energy Services’ Open Hole (OH) Services deliver reliable, high-resolution formation evaluation solutions that support confident reservoir characterisation and well planning. Operating under our Wireline Division and based in Trinidad, Open Hole Services are primarily focused on land-based operations, with the flexibility to adapt to a wide range of geological and operational environments.
With more than 30 years of local and regional experience, TES has built a strong reputation for providing accurate, timely and high-quality open hole logging data. Our services play a critical role in enabling safe drilling operations, optimising well placement and supporting informed reservoir and completion decisions throughout the well lifecycle.
Advanced acquisition technology
TES utilises an advanced digital acquisition system, delivering high data integrity, real-time quality control and operational efficiency. Our industry-proven Triple Combo logging string is among the shortest in the market, significantly reducing rathole requirements while minimising rig time and associated costs, without compromising data quality.
Integrated interpretation & data quality
Our Open Hole services are supported by a dedicated Data Processing Centre and experienced in-house Log Analysts, equipped with industry-leading interpretation and processing software. This integrated approach ensures consistent data quality, rapid turnaround and actionable insights, even in complex or challenging formations.
By combining advanced technology, experienced personnel and a strong understanding of local geology, our Open Hole team delivers dependable formation evaluation solutions designed to reduce uncertainty, enhance reservoir understanding and maximise asset value.
