The Halliburton collaborative framework for mature fields’ diagnoses challenges, designs solutions to improve production and increase recovery, and delivers these solutions to enable you to maximize the value of your assets. In a recent project, we found potential for a client to increase their total production by over 250%, with a rate of return of over 200%, within a matter of months. These benefits were forecasted at a fractional capital investment from the client.
Case Study: Asia Pacific Mature Fields
For offshore gas condensate fields in South East Asia, our Reservoir Monitor Tool 3-Detector™ (RMT-3D™) was used to determine saturation behind casing. The RMT-3D™ results were compared with re-interpreted legacy open hole logs to identify and rank potential new pay zones. Concurrently, decline curve analysis using the Dynamic Surveillance System (DSSTM) was conducted to determine and rank remaining reserves in existing pay zones. Our team of global and local subject matter experts defined feasible technical solutions based on the range of challenges identified. The potential production uplift from each technical solution was modeled and evaluated using nodal analysis. The economic performance of each technical solution was evaluated using the expected production increase and the expected cost of the solution. A final ranking of solutions was performed using the expected economic performance. The figure below shows the workflow that was followed to filter the wells with the highest potential and then rank them according to economic value.
Twenty-eight percent of the total wells were found to have opportunities for significantly increasing production through the application of technologies such as our VannSystem® tubing conveyed perforating, SandWedge® sand control technology, and H2Zero™ technology. Of this 28%, 38% would require full workovers, closing off zones with high water cuts, opening new zones, and stimulating all intervals. Sixty-two percent would involve relatively low-complexity wireline interventions such as, perforation and re-perforation.
Mature Fields: Increase Hydrocarbon Production, Reduce Your Cost per BOE
In many regions, developing new wells is not possible due to the current market conditions so companies are shifting their attention to mature fields and their existing infrastructure. We have been successfully employing mature field solutions for clients whose goal is to rapidly increase hydrocarbon production from existing wells without increasing cost per BOE. Our process consists of first assembling cross-functional teams that are coordinated by our group of global consultants. The team’s primary task is to identify the mature field’s main technical challenges and propose immediate impact and new pay solutions that are feasible based on the equipment and technology available right away in-country. We also deliver mid- to long-term reservoir optimization solutions by working on-site in close collaboration with the client’s petrotechnical and financial teams.
Broadly, our three primary Mature Field solutions are:
- Immediate impact interventions – production-based, well-centric solutions that generate more oil—today.
- Optimized reservoir management – reservoir-based, field-centric solutions that optimize recovery rates to ensure the most profitable long-term plan.
- New pay solutions – petrophysical rediscovery techniques that unlock more pay in existing mature fields.
The production uplift solutions identified by the project team have the potential to dramatically increase the asset’s total production with a relatively low investment. The success story identified above demonstrates that, in today’s challenging market, we can help you maximize the value from existing assets while reducing your costs per barrel of oil.
