¿Qué es TDH?
TDH is a fully featured well engineering software platform for drilling engineers working across exploration, appraisal and development wells in oil, gas, geothermal and CCS.
At its core, TDH enables engineers to understand and manage system loads versus limits, building models to define the loading envelope created by the well and comparing these directly against the capability of the rig and rocks being drilled.
Proven on the world’s most complex wells, TDH combines advanced modelling capability with engineering insight, supporting a holistic approach to well construction based on a clear understanding of risk and the margins available to push performance.
Built from the ground up to meet Merlin’s exacting technical requirements, TDH is used daily in both office and field environments. It requires no local installation and is designed to be flexible, scalable and simple to adapt.
TDH is designed to give engineers speed, simplicity and consistency where it matters, building models quickly and focusing time on understanding results, not wrestling with software. Whether used daily or intermittently, TDH provides a consistent, intuitive environment that reduces rework and keeps the focus on engineering decisions.
Beyond core torque, drag and hydraulics analysis, TDH brings together a comprehensive set of modelling and analysis capabilities within a single platform. Engineers can define trajectories, wellbore architecture, strings and fluids, and apply detailed analysis across torque and drag, hydraulics, casing wear, cementing and casing design, all within a consistent, integrated workflow.
TDH supports advanced engineering workflows, including upcoming real-time data integration, data hindcasting, LAS data viewing, scenario comparison and sensitivity analysis, enabling direct comparison of models against system limits and measured field data. This allows engineers to move beyond standalone calculations and build a clear, continuous understanding of well behaviour from design through execution.
Built-in functionality supports detailed modelling of real-world conditions, including friction modifiers for centralisers and swivels, flotation effects, tortuosity, PVT-corrected hydraulics and complex fluid behaviour – without the need for workarounds or external tools. Results can be visualised, compared and reported quickly, supporting clear communication and consistent engineering alignment across teams.

TDH Personalizado -
Customised TDH solutions tailored to your exact specification. Example projects for real clients shown below.
TDH Personalizado - Ejemplo #1:
Un cliente quería optimizar la colocación de sus herramientas innovadoras en la sarta de perforación con funcionalidad de un solo clic. El encargo se asignó a Merlin para el desarrollo de un modelo digital del mecanismo operativo de la herramienta desde los conceptos básicos, que se utilizaría para definir mapas de torque y arrastre según la posición de colocación y el número de herramientas en la sarta. Estos modelos fueron luego validados con mediciones reales y observaciones en el campo.
Tras un proceso de validación exitoso TDH fueron modificadas para reemplazar las hojas de cálculo que se utilizaban para recopilar datos de distintas fuentes en un único lugar. La capacidad flexible de generación de reportes de TDH se empleó para producir automáticamente un informe equivalente, sin necesidad de manipulación manual, lo que permitió a los ingenieros dedicar más tiempo a la resolución de los problemas de los clientes.
TDH Personalizado - Ejemplo #2:
Un proveedor independiente de herramientas quería incorporar las características operativas de sus herramientas en TDH para agilizar su proceso de modelado y generación de propuestas para clientes. Se añadieron herramientas personalizadas como opciones desplegables en la sección de entrada del BHA, donde se podían especificar herramientas individuales como parte del BHA, y sus características operativas se incorporaban automáticamente.
