hydraulic fracturing

This paper presents a mathematical analysis of how incorrect estimates of initial reservoir pressure may affect rate-transient analysis in ultralow-permeability reservoirs.

The key element of hydraulic-fracture modeling is the prediction of the generated fracture geometries. Research conducted over the years has trickled down predictive software. Nevertheless, the ability to design optimal fracture treatments is hampered, as we cannot “see” the subsurface.

This paper illustrates efforts undertaken to evaluate high-viscosity friction reducers and crosslinked gel products, their successful field application, and the importance of maintaining an effective field/laboratory/field cycle.

Hitting the next well during fracturing happens all the time. Predictably doing that on a large scale in granite looks a lot harder.

The latest ruling reverses a lower court decision to block the Ecopetrol and ExxonMobil programs in the Andean nation.

The past decade has seen many technological innovations in the well-completion domain focused on hydraulic fracturing. Within openhole multistage completions, we have seen a wider use of higher-expansion-ratio packers, fracturing-sleeve configurations, multicluster fracturing sleeves, dissolvable ball and seat technologies, and reclosable sleeves. When we look at case…

Liberty will be integrating Seismos’ measurements-while-fracturing system into its completions service to analyze near-wellbore fracture networks and create a near-field connectivity index.

This paper presents an optimization project that was implemented in the Khazzan and Ghazeer fields of Oman to optimize the post-fracturing cleanup and testing period to reduce hydrocarbon flaring and CO2 emissions as well as the testing cost without compromising the overall well cleanup and testing objectives.
