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.

Advancement of the integration of seismic with other oilfield disciplines has been fueled by two factors. First, advances in seismic technologies naturally led to more-powerful integration. Second, developments in seismic were motivated in direct response to the needs of interpreters and engineers.

Cost optimization in heavy-oil production can be achieved through numerical modeling to suggest general optimal strategies and development plans or by using proper real-time data acquisition … for prompt decisions while operations are ongoing.

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.

A real-time production-surveillance and -optimization system has been developed to integrate available surveillance data with the objective of driving routine production optimization.

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.

This paper describes how the use of production-modeling tools, coupled with field pressure/temperature-data-acquisition systems and programming software, served as a means to improve production allocation and surveillance on a real-time basis in the Greater Angostura Field.

The authors used a high-quality digital-log data set to characterize reservoir quality accurately in the Niobrara and Codell Formations in the Denver-Julesberg (DJ) Basin.

A new tool enables variable bore rams and shear rams to be tested in one run, cutting rig time significantly.
