Reservoir characterization
The technology has passed its first phase of qualification, with 84 nodes placed on the seafloor at a depth of 2,000 m to acquire 4D seismic data in the pre-salt Santos Basin.
Xu outlines the thinking and theories that led his team to six world-class oil discoveries that total more than 100 million tons of proven geological reserves since 2021.
This case study from SLB and offshore producer PRIO describes the longest openhole section in Latin America with the highest extended-reach drilling ratio in Brazil’s history.

Newly developed ambient seismic imaging methods provide valuable information throughout the life cycle of an unconventional field. -
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.
-
The pursuit of sweet spots in unconventional oil and gas plays is driving the creation of an emerging set of data-driven systems to measure, map, and predict how wells will perform in unconventional reservoirs.
-
Permanent downhole gauges (PDGs) provide vast amounts of pressure-transient and rate data which may be interpreted with improved pressure-transient-analysis (PTA) approaches to gain more knowledge about reservoir dynamics.
-
This paper focuses on the aspects of proppant selection and adequate fracture-conductivity placement, with the goal of improving well productivity and cumulative recovery.
-
This paper provides a more straightforward method for estimating stress-dependent permeability and capillary pressure in rock fractures.
-
In hydraulic fracturing, the use of diagnostic-fracture-injection tests (DFITs) can provide valuable information.
-
When it comes to fracturing, experts argue about many things, but they agree that fractures do not look like lightning bolts, tree roots, or shattered glass.
