Tech Paper: Enhance Production by Infinite Conductivity Technique Applied in Tight Formations

Pulsed proppant fracturing process helps provide enhanced and sustained production over conventional treatments The infinite conductivity theory to enhance production was introduced to the industry around 1971. Exploration from the 1970s to the 1990s focused on high permeability formations. The unconventional reservoirs and tight formations were left behind until new technology could enable hydrocarbons to be produced in economical manner. Operators seek methods to both increase...

Case Study: Mobile Testing Package Enables Early Production

Mobile express surface well testing system helps operator achieve production goals in new fields CHALLENGE – Parnaíba Gás Natural S.A. operates in Maranhão State and is responsible for about 10 percent of all natural gas produced in Brazil. While some of its fields are equipped with permanent measuring equipment, some of its remote wells are currently using the mobile express surface well testing system. Brazil’s industry...

Tech Paper: Fast Track Well Planning Borneo

Malaysian operator uses collaborative well planning method in their first fast track drilling operation in deepwater This paper highlights the phenomenal achievement of a Malaysian operator’s first fast track drilling operation in a deepwater well offshore Borneo. The collaborative well planning (CWP) method fundamental to the drilling success is discussed. The discussed drilling environment is an overpressured deepwater area that has not only forced the earlier...

Mature Field Rejuvenation with Top Hole Re-completion –Using Cement Packers

Accessing bypassed oil to capture bypassed cash-flow The oil and gas industry has been hard-hit by the economic downturn. We find ourselves dealing with an unprecedented situation: most financing channels are at punitive rates, and the equity capital markets are an option only for a select few. With oil prices only slowly recovering, there is an industrywide sense of urgency to identify ways to lower costs,...

Tech Paper: High Performance Water-Based Mud HPWBM: Turning Old Ways into New Opportunities

Novel alternative fluid system helps reduce waste management cost for both onshore and offshore wells For decades, wells targeting the Rotliegend reservoir in the Southern North Sea Basin have been drilled using conventional water-based mud (WBM) in the top hole section and oil-based mud (OBM) systems throughout the remaining sections of the well. The standard well design generated high waste disposal costs onshore and offshore, particularly with...

Case Study: GeoBalance® Service Helps Operator Save Big in Challenging Deepwater Environment

Automated managed pressure drilling system successfully drills ‘undrillable’ wells in 2,000 meters of water CHALLENGE – The operator elected to use managed pressure drilling to overcome these challenges. This project would also be the world’s first implementation of a MPD surface control system onto a MPD ready drill ship. The safe and successful implementation of Halliburton’s GeoBalance® MPD technology required an engineered approach working closely with...

Tech Paper: Field Application of an Innovative, Minimally Damaging Low-ECD Invert Emulsion Fluid for Drilling and Completion of HP/HT Wells: Update on Fluid Performance

Invert emulsion fluid helps operator save time and money while drilling on an HP/HT field Previous publication SPE-174176-MS discussed the development of a novel high-pressure/high-temperature (HP/HT) organophilic clay-free (OCF) invert emulsion fluid (IEF) for first use as a combined reservoir drilling fluid (RDF) and screen running fluid (SRF) for stand-alone screen (SAS) completions. The current paper details the continued application of this innovative fluid in a...

Tech Paper: Multilateral TAML-4 and -5 Junctions Provide Consistent Results for Arabian Gulf Operator

Successful implementation of multilateral technology expands the use of multilateral completions in the Middle East Since 1999, more than 120 wells in Saudi Arabia have been completed using multilateral technology (MLT). This paper will discuss case histories, associated technology improvements, and best practices in which dual-lateral completions, with and without pressure-isolated junctions (Technical Advancement of Multilaterals (TAML) levels 4 and 5), were developed and used to help ensure...

Case Study: Record-Setting Lateral Completion Achieved with Obsidian® Plugs

Halliburton and Eclipse Resources set 124 frac plugs averaging 5.3 frac stages per day CHALLENGE – Setting and drilling out 100 + frac plugs in an extended-reach 18,544 ft lateral is no easy feat, so finding a reliable, field-proven completion solution was key. Eclipse Resources considered running a sleeve system for the extended lateral; however, Obsidian® plugs proved to be a more economical option, and past...

Tech Paper: First Integrated Petrophysical Characterization in Limestone in Ecuador: M1 and M2 Limestones, Puma Field

Dual porosity characterization method helps access potential carbonate reservoirs The first integrated characterization of limestone in Ecuador was performed in the M1 and M2 limestones in the Puma field of the Oriente basin. The characterization was performed by using available information from open hole logs and by applying the dual porosity methodology, which requires the use of porosity curves, including density, neutron, and sonic. The method...
