Low-Permeability Sandstone Reservoir Stimulation Program

Project Overview

JJM personnel conducted a multi-disciplinary subsurface opportunity review across an operator’s field area to identify opportunities to enhance production from a low-permeability sandstone reservoir play. The review identified several production optimisation and well stimulation opportunities capable of improving reservoir deliverability and increasing recoverable reserves. JJM personnel subsequently designed and executed a stimulation campaign involving fracture stimulation and well recompletion activities to enhance reservoir connectivity and restore well productivity.

Project Details

• Location: Queensland, Australia

• Industry: Conventional Oil and Gas

• Scope: Well Engineering, Fracture Stimulation, Project Management

Scope of Work

• Multi-disciplinary subsurface opportunity review of field development potential

• Reservoir and production performance analysis for candidate wells

• Detailed design of fracture stimulation programs

• Diagnostic fracture injection testing (DFIT) to evaluate reservoir properties

• Development of a mechanical earth model to inform stimulation design

• Preparation of material specifications and well equipment requirements

• Tendering and procurement of stimulation services and materials

• Direct supervision of hydraulic fracture stimulation operations

• Management of well flowback and post-stimulation clean-up activities

• Well intervention and recompletion operations

• Production testing and performance evaluation

• Completion of statutory post-operations reporting and reserves review

Key Challenges

• Enhancing productivity from a low-permeability sandstone reservoir with limited natural deliverability

• Designing stimulation treatments compatible with reservoir geomechanics and well architecture

• Integrating fracture stimulation operations with existing well completions and infrastructure

• Managing operational risks associated with high-pressure stimulation treatments

• Evaluating post-stimulation well performance to determine impact on recoverable reserves

Outcome

The stimulation campaign was delivered safely, on schedule and within budget. The wells were successfully returned to production following stimulation and recompletion activities, with production testing confirming improved reservoir deliverability. The project resulted in an uplift in proved and probable reserves and demonstrated the effectiveness of targeted stimulation techniques in unlocking additional value from the operator’s existing asset base.
