Magnetostratigraphy and cyclostratigraphy of the Tithonian interval from the Vaca Muerta Formation, southern Neuquén Basin, Argentina [PDF]
Journal of South American Earth Sciences, 2018 A cyclostratigraphic and paleomagnetic study was carried out in the lower part of the Vaca Muerta Formation, Los Catutos Member (Lower to lowermost Upper Tithonian) at the southern region of the Sierra de la Vaca Muerta, Neuquén Basin, west-central ...

Vaca Muerta Formation: An Example of Shale Heterogeneities Controlling Hydrocarbon Accumulations
Proceedings of the 2nd Unconventional Resources Technology Conference, 2014Vaca Muerta Formation, a thick Upper Jurassic unit covering at least 25,000km 2 , is located in Neuquen Basin and represents the most important source rock in Argentina. Its geological and petrophysical variations are significantly linked to the geodynamic history of the basin strongly related to the transition from extensional reactivation to thermal ...

Dual Porosity Modeling for Shale Gas Wells in the Vaca Muerta Formation
SPE Latin America and Caribbean Petroleum Engineering Conference, 2017Abstract The Vaca Muerta shale has been developed for oil and gas production since 2010 and to date nearly 500 wells have been drilled. The large amount of static and dynamic information from these wells has enabled fracture design and production strategy optimization.

Drilling Horizontal Well of 3200m Lateral Length in Vaca Muerta Formation
SPE Argentina Exploration and Production of Unconventional Resources Symposium, 2018ABSTRACT OBJECTIVES At a time when the demand for energy is growing in Argentina, operators are seeking to improve the profitability of unconventional oilfields by drilling wells with longer lateral lengths (up to 3200 meter), allowing a larger area to be drained by single wellbore, minimizing overall

Outcrop to Core Comparison of Natural Fractures in the Vaca Muerta Formation, Argentina
Sixth EAGE Shale Workshop, 2019Characterizing permeability-controlling fracture attributes is essential for well planning and stimulation design, especially in unconventional reservoirs. Outcrops allow to measure fracture attributes that are below seismic resolution or cannot be readily sampled by core, such as fracture height and length.

Diagenesis and alteration of subsurface volcanic ash beds of the Vaca Muerta Formation, Argentina
Marine and Petroleum Geology, 2021Abstract The Vaca Muerta is a marine source rock with excellent petroleum potential containing a large range of heterogeneities such as natural fractures filled with fibrous calcite (“beef”), concretions and ash beds. An exhaustive diagenetic study of ash beds samples was carried out, based on petrographic, mineralogical and geochemical ...

Multiphase Choke Correlation Improving Matching Field Data on Vaca Muerta Formation
Day 1 Mon, March 20, 2023, 2023Abstract In Non-Conventional fields, wellhead chokes are widely used to regulate the flow rate of the well to impose sufficient back pressure on the face of the sand so as not to exceed values of excessive drawdown. Many authors describe and model flow through chokes, but only with laboratory data. These models work well, and their error

Hydraulic Fractures Behavior Evaluation in Vaca Muerta Formation, Case Studies
SPE Argentina Exploration and Production of Unconventional Resources Symposium, 2016Abstract The objective of this work is to show that the estimated stimulate reservoir volume (SRV) from micro seismic analysis under dynamic conditions not always represents the SRV acting as hydrocarbon collector and need to be calibrated with total organic content (TOC), vertical and areal distribution. Furthermore, unlike conventional

ABSTRACT The term “beef” describes bedding-parallel calcite veins found commonly in the organic-rich matrix of unconventional resource plays. Although some authors have interpreted beef to be an early diagenetic feature, these calcite veins are commonly attributed to precipitation at high temperatures and localized overpressure during
