Fracturing/pressure pumping
This case study from ARC Resources and DarkVision outlines the use of acoustic imaging tools in two active fracturing programs in Canada to monitor well casing deformation.
The creation of SPE’s Acid Stimulation Technical Section shines a light on the technique that improves injectivity and productivity. JPT talked with the chair of the new section about the importance of the technical area.
Fracture modeling continues to be used to evaluate and design novel applications, and integration with diagnostics and other forms of field-data collection are crucial to success.

Early testing suggests that grains of proppant so small they need to be measured in microns can add production by slowing the notoriously rapid declines in unconventional wells. -
With newly discovered fields and the extension of existing areas, the challenges related to reservoir heterogeneity, tight rock, layered systems, and field maturity have led to innovative ideas and to testing and application of technologies.

Recent studies have found that the viscosities of borate gels at actual downhole pressure conditions may be 80% less than those from standard high-pressure/high-temperature rheometer measurement (which uses 400-psi top pressure).
-
This paper examines the chemistry of developing seawater-based fracturing fluids using two types of polymers as gelling agents and compares results to existing fresh-water-based-fracturing-fluid data under different conditions.
-
This paper presents the results of a comprehensive multiphase-flow study that investigated the relationship between the principal stresses and lateral direction in hydraulically fractured horizontal wells.
-
The objective of this study is to validate the concept of using a seismically derived discrete fracture network (DFN) calibrated with borehole measurements, for complex-hydraulic-fracture modeling.
-
Always recorded but almost never used, the water hammer signal could offer completions engineers another set of insightful data if petroleum engineers can crack its code.
-
PDC’s president and CEO describes the company’s management strategy for its hydraulic fracturing operations in the Wattenberg Field and the Delaware Basin.
-
Permian Basin producer Callon Petroleum is attributing its data-driven approach to a routine completions practice to improved proppant placement and higher oil production.
