Halliburton Landmark DecisionSpace 365: cloud software for subsurface and drilling workflows

Responsible: ad hoc news Software & Services Desk. Reviewed prior to publication on June 12, 2026 at 4:39 PM ET. Details in the imprint.

Landmark DecisionSpace 365 from Halliburton is a cloud-native software suite designed to run subsurface interpretation, reservoir modeling, and well construction workflows on Microsoft Azure. Halliburton markets DecisionSpace 365 as a collection of open, integrated applications that bring exploration, drilling, and production data into a single workspace for technical teams. The software is offered as a subscription service, with deployment through the Landmark iEnergy Cloud or a customer’s own Azure environment for flexibility in large enterprise deployments. For U.S.-based upstream companies, the appeal lies in combining petrotechnical workflows, data management, and AI-assisted analytics without maintaining on-premises high-performance computing infrastructure.

What DecisionSpace 365 does for oil and gas workflows

DecisionSpace 365 groups multiple cloud applications under one umbrella, covering domains such as seismic interpretation, geological modeling, petrophysical analysis, drilling engineering, completions, production optimization, and asset performance management. Halliburton highlights that users can access these applications through a common workspace and data environment, which aims to reduce data silos between geoscience and drilling teams. The platform builds on Landmark’s long-running DecisionSpace environment but shifts the computing backbone to Azure, enabling elastic scaling of storage and compute for large subsurface models and simulations.

According to Halliburton’s official product information, DecisionSpace 365 is delivered as a software-as-a-service (SaaS) offering that uses open-standard data services and APIs to connect with existing data sources. The company positions this openness as a way to integrate vendor-neutral well data, seismic volumes, production histories, and engineering models within one framework instead of locking customers into proprietary data formats. For operators that already maintain data platforms such as OSDU Data Platform on Azure, DecisionSpace 365 can be layered on top to provide interpretation and engineering applications that consume those standardized data stores.

In practice, the suite is divided into several solution families. Landmark describes subsurface workflows under DecisionSpace 365 Subsurface, which targets seismic interpretation and reservoir characterization. Drilling and completions are covered by DecisionSpace 365 Well Construction, focusing on well planning, trajectory design, and real-time operations support. Production and asset performance monitoring are addressed through DecisionSpace 365 Production, which includes tools for network modeling, surveillance, and optimization of fields with multiple wells and gathering systems. These solution families are licensed separately, so operators can subscribe to domains that match their asset portfolios and technical staff.

Halliburton also underscores the use of artificial intelligence and machine learning in several DecisionSpace 365 applications. Examples include assisted seismic interpretation, automated fault and horizon picking, and pattern analysis on production data to highlight underperforming wells or equipment anomalies. By running these workloads in the cloud, the platform can train and deploy models on larger datasets than many on-premises setups would typically handle. For U.S. independent operators that have grown through acquisitions and inherited fragmented datasets, consolidating information in DecisionSpace 365 can support data quality initiatives and accelerate technical evaluations.

From an IT operations perspective, DecisionSpace 365 leverages Azure’s security, identity, and compliance features, including Azure Active Directory integration and regional data residency options. Halliburton’s iEnergy Cloud is presented as a managed environment where Landmark engineers provision and operate the software stack for customers that prefer an off-the-shelf managed service. Larger oil majors and national oil companies can opt for deployment in their own Azure subscriptions, maintaining direct control over cloud infrastructure while consuming Landmark updates and patches through the SaaS delivery model. In both scenarios, the subscription approach shifts spending from capital expenditures on hardware toward operating expenditures tied to software usage and support agreements.

In the U.S. market, DecisionSpace 365 primarily targets exploration and production companies, supermajors, and large independents that require multi-asset portfolio modeling and drilling programs. Service companies and engineering consultancies also appear in Halliburton’s target group, particularly for project-based reservoir studies and well-engineering services that need secure collaboration with operator data. Pricing is typically custom and contract-based; Halliburton does not publish a public MSRP for DecisionSpace 365, and subscription terms depend on the number of users, selected application families, and infrastructure choices. Because of that, prospective U.S. customers generally engage directly with Landmark sales or through the Halliburton website to scope deployments and license configurations.

For Halliburton, DecisionSpace 365 fits into a broader strategy of expanding digital revenues and deepening long-term relationships with upstream clients. The platform complements the company’s hardware and services offerings in drilling, completions, and production, creating opportunities to bundle digital workflows with field operations and project management. While Halliburton does not break out DecisionSpace 365 revenues separately, digital and consulting services are highlighted as part of its strategic growth pillars in recent investor communications. Shares of Halliburton (US4062161017, ticker HAL) traded at $39.90 on NYSE on June 12, 2026.
