Reservoir characterization
This paper presents a case study from a mature field redevelopment project where pulsed neutron logging was integrated with advanced reservoir modeling to improve the understanding of fluid-contact dynamics and optimize new horizontal well placement.
This paper presents an experiment investigating dissolution of basaltic primary minerals and conditions favorable for secondary phase formation under deep subsurface storage conditions.
The industry is no longer short of measurements; the real challenge is converting them into timely reservoir decisions that protect value. That challenge is becoming more urgent as the industry depends increasingly on mature fields and existing infrastructure. The selected papers show how this need is being addressed across different producing regions.

An area of great interest to those researching flowback is the interaction of water and salt inside the shale reservoir. After a well is stimulated, the flowback fluids tend to show a rising concentration of salt that falls back to near zero over time.

A surge in earthquakes tightly clustered in southern Kansas that followed the large increase in produced water injections prompted the state to cut the daily limits on disposal wells in that area to see if that will help solve the problem.

Reservoirs consisting of heterogeneous carbonates and shaly sands pose formation evaluation challenges for conventional logging-while-drilling (LWD) measurements. Magnetic resonance techniques hold promise for improving understanding of these reservoirs.

More than 50 years after inventing the air gun, Stephen Chelminski is working on a new version of the industry standard designed to be more in tune with the current needs of the industry and its regulators.

Pulled directly from the reservoir rock, core samples provide critical data used to determine how exploration should proceed. Until recently, core analysis remained old school, however, there is an ongoing transition to bring the process of core description into the digital age.
-
New seismic data gathering techniques promise better images for less by gathering more data quicker, seeing past obstructions, and seeking out scarce frequencies.
-
The word “broadband” is used to sell a lot of what is new in offshore seismic. It can mean different things depending on who is speaking.
-
Companies are using an increasing number of sound shots to gather more data in a shorter time frame.
-
Developing the Mad Dog discovery appeared to be high-risk because of the difficulty in mapping the subsurface because of the thick layer of salt underlying the region.

Newly developed ambient seismic imaging methods provide valuable information throughout the life cycle of an unconventional field.
