Featured this monthFiber Optic Sensing – Learning How It Really Feels DownholeInterest is growing in using fiber optic cable to listen to what is going on inside wells beyond pressure and temperature measurements.
Guest Editorial The good news is that there is plenty of innovation to talk about regarding step-change advances in horizontal multistage fracturing in many of the existing and emerging resource plays. The bad news is that you will not find these being applied in the legacy or high-profile shale plays.
R&D Grand Challenges: Higher Resolution Subsurface Imaging An overview of the challenges of getting higher resolution subsurface images of hydrocarbons, and emerging research trends and technologies aimed at delivering a more accurate reservoir picture.
Talent & Technology Three new awards are designed to help reverse a growing shortage of petroleum engineering faculty.
Distinguished Author Series Hydraulic stimulation has advanced the development of lower-permeability resources, but the corresponding challenges have not been addressed fully. Here is a perspective on future opportunities for improving recovery of hydrocarbons from tight reservoirs.
OTC 2012: The Wide World of Offshore Technology A preview of the 2012 Offshore Technology Conference.
Karen Olsen, SPE, Completion Expert for Southwestern EnergyIt is a good time to be in the oil industry. The rig count, drilling activity, and oil prices are high, and shale plays are a significant reason for each. And, because it is shale, it is an especially good time to be a completion engineer!
Fracturing-Fluid Effects on Shale and Proppant Embedment Development of shale reservoirs has grown significantly during the past few decades, driven by evolving technologies in horizontal drilling and hydraulic fracturing. The productivity of shale reservoirs depends highly on the design of the hydraulic-fracturing treatment. To design a successful treatment, a good understanding of the shale mechanical properties is necessary. The results of this […]
Stimulation Influence on Production in the Haynesville Shale: A Playwide Examination In most developing shale plays, there is a learning curve for determining which factors affect well production positively and are economical. Evaluating the reservoir on a playwide basis can expedite the ability to determine the optimal treatment method. By use of public production data with a database of stimulation treatments for several hundred wells in […]
Distributed Acoustic Sensing for Hydraulic-Fracturing Monitoring and Diagnostics Distributed acoustic sensing (DAS) is a fiber-optic technology that enables detecting, discriminating, and locating acoustic events with a standard telecom single-mode fiber several kilometers in length. Use of a combination of the measurement of backscattered light and advanced signal processing enables the DAS interrogator system to segregate the fiber into an array of individual "microphones." […]
Francisco J.S. Alhanati, SPE, Director of Exploration & Production, C-FER TechnologiesAt the 2011 SPE Annual Technical Conference and Exhibition in Denver, there were many interesting discussions on shale-gas (and/or liquid-rich) resources. While already an important part of the industry, we are just beginning to identify some of the challenges with these resources and how best to deal with them.
Evaluating Production-Log Data From Horizontal Organic-Shale Wells Production logs from more than 100 horizontal shale wells in multiple basins were interpreted. The evaluation confirmed that production is highly variable along the length of the wellbores. In some basins, two-thirds of gas production comes from only one-third of the perforation clusters. Further, when looking at all basins, almost one-third of all perforation clusters […]
Very-High-Volume ESP-Lift Systems For Shale-Gas Fracture-Water Supply One challenge of the Horn River shale play in British Columbia, Canada, has been the increasing number of fracture stimulations required per horizontal wellbore. Critically important is the massive volume of water required to supply the continuous fracturing operations in the development. To eliminate reliance on surface water, it was decided to produce high volumes […]
Factors Affecting Downhole Scale Deposition: North Dakota Bakken Formation Oil recovery from the North Dakota Bakken formation has increased nearly 100-fold over the last 5 years. For one North Dakota operator with 150 Bakken producing wells, 22 of the wells have experienced at least one event of severe calcium carbonate scaling in the pump and production tubing, leading to well failure. A study showed […]
