Can Additive Manufacturing Breathe New Life Into Aging Assets?
Additive layer manufacturing technology has gained prominence in the aerospace sector and is being used for the rapid production of prototype parts. Its credibility has quite literally “taken off” and is now used to build in-flight production components for aircraft.
Novel Brownfield-Rejuvenation Approach Uses Near-Wellbore-Saturation Monitoring
Fields in the Upper Assam-Arakan Basin have been studied intensely to find prospective sweet spots, perforation intervals for new wells, and potential workover candidates. These forecasts, guided only by dynamic-numerical-model results, have had mixed results when implemented in the field.
Integrated Water-Injection Analysis Uses Salinity as Tracer in Giant Brownfield
In this paper, an integrated work flow is proposed for brownfields where oil production is driven mainly by water injection. Produced-water salinity plays a key role, acting as a natural tracer and, thus, helping avoid additional costs for new data acquisition.
Data-Driven Technologies Accelerate Planning for Mature-Field Rejuvenation
This paper presents a data-driven technology and associated work flow for fast identification of field-development opportunities in mature oil fields that accelerates subsurface field-development planning and reduces the time requirement from months to weeks.
Mature Fields and Well Revitalization
There is a growing awareness that maximizing field production involves not only having a clear understanding of subsurface intricacies but also ensuring that existing surface facilities are performing at their best to handle production in an environmentally safe manner.
Mature Wells and Field Revitalization
I would like to steer readers’ attention to new technology, advanced modeling, and the interesting topic of fracture hits.
Tapping Difficult Oil in a Giant Carbonate Field in Qatar
After 70 years of production, more than 30% of the Arab C reservoir stock-tank original oil in place has been recovered through various mechanisms including natural depletion, waterflooding, gas lift implementation, and horizontal-well development.
New Technology in a Mature East Malaysian Field
This paper describes the first job in southeast Asia in developing horizontal-well placement in a turbidite environment.
Use of Modern Reservoir Characterization in Mature Fields To Unravel Hidden Reserves
This paper discusses the successful, fully integrated, 3D Earth modeling (EM) and dynamic reservoir simulation of the Hollin Formation in the Lago Agrio Field within an operator’s first producer field in Ecuador.
India Road Tests Its E&P Growth Plan
An auction of small discoveries that were passed over by India’s national oil companies is a test of the country’s efforts to boost oil and gas development by encouraging participation from inside and outside this energy-hungry country.
Breaking From the Norm To Reach Marginal Offshore Fields
A number of companies are pushing for alternative approaches to offshore development that seek to access marginal reservoirs. Their differing and unique ideas call for a departure from the usual playbook, but share a common goal of slashing capital costs.
Achieving Well-Performance Optimization Through Work-Flow Automation
The Samarang oil field, offshore Sabah, Malaysia, is undergoing a redevelopment project with integrated operations. Several work flows were designed and deployed in order to achieve an early milestone of providing real-time well-performance monitoring, surveillance, and optimization.
Refracturing: A Second Chance To Get It Right Through Diagnostics
The surge in unconventional completions has created a substantial accumulation of previously hydraulically fractured wells that are candidates for hydraulic refracturing.
Mature Fields and Well Revitalization
The surge in unconventional completions over the last decade has created ample candidates for hydraulic refracturing, which has been demonstrated to be a viable alternative to the more expensive endeavor of drilling and completing new wells.
An Integrated Methodology To Locate Oil Opportunities in Mature Reservoirs
A matured field is currently producing with greater than 85% water cut (WC) and has significant levels of uncertainty with respect to oil/water contact (OWC), flank structure, depth of spill points, production allocation, and residual oil saturation.
