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...

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...

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...

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...

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...

Tech Paper: Innovative Sidewall Pressure Coring Technology Improves Reservoir Insight in Multiple Applications

New tool helps eliminate the loss of important reservoir fluids during core recovery process Oil and gas exploration and development projects require reservoir properties that need to be evaluated to help ensure both economic and operational success. These reservoir properties include determination of the volume of original hydrocarbon in place, the residual hydrocarbon saturation after sustained production, and the reservoir drive mechanisms. Additionally,...

Tech Paper: Improving Fiber-Optic System Reliability in Permanent Installations

Monitoring the health of fiber-optic system can save time and money Permanent installation of fiber-optic (FO) sensors, whether discrete or distributed, provides beneficial monitoring of a wide variety of parameters during every stage of a well’s useful life—from drilling and completions, through the productive period, up to and including permanent abandonment—assuming that the sensors do not fail during installation or subsequent wellbore intervention...

Tech Paper: Efficient Use of Data Analytics in Optimization of Hydraulic Fracturing in Unconventional Reservoirs

Understanding reservoir parameters can help successfully optimize fracturing treatments per well Hydraulic fracturing operations affect reservoir flow dynamics and increase production in unconventional tight reservoirs. The control of fracture growth and geometry presents challenges in formations in which the boundary lithologies are not highly stressed in comparison to the pay zone, thus failing to prevent the upward migration of fractures. Several factors influence...

Tech Paper: Nonexplosive Tubing Perforator Offers Controlled Cost-Effective Solution for Through-Tubing Gas Lift Installation

User friendly mechanical perforator eliminates need for explosives, helping to improve safety and reduce rig time An operator in Baku, Azerbaijan was planning to create a gas lift configuration and needed to perforate 7-in., 32-lbf, 13% chrome, up to 0.51-in.wall thickness, heavy wall tubing without explosives. A nonexplosive mechanical tubing perforator conveyed on electric line avoided damaging the in-situ control lines and the...

Tech Paper: Size Degradation Studies of Lost Circulation Materials in a Flow Loop

When drilling problem zones in mature fields, it is important to use resilient lost circulation materials Recently, there has been significant interest in understanding the material properties of lost circulation materials (LCM), including size degradation studies from mechanical compression tests and from shear flow. These types of tests are currently of particular importance because of increased drilling activity in mature fields, which often require...
