This paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
-
The industry has developed a deep and healthy respect for systems-engineering processes and the associated full considerations during the deployment of new technologies. The result has been a significant improvement in the successful use and broader deployment of these attractive technologies. -
In North America’s most active shale fields, the drilling and hydraulic fracturing of new wells is directly placing older adjacent wells at risk of suffering a premature decline in oil and gas production.
-
A closer look at technological and mechanical solutions being developed to limit exposure to respirable silica dust during hydraulic fracturing operations in the wake of US government regulations.
-
Technology that allows researchers to see stress forming inside rock samples may help unravel some of the mysteries associated with fracture behavior.
-
The Austin Chalk play could go through a revival if the industry can view the formation through “a fresh set of eyes,” says EnerVest’s Tony Maranto.
-
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.
