Shale Basic Knowledge

In this category is explained the shale gas and oil industry, what are the mains differences between un-conventional fields and conventional, which are the news techniques to develop it, how works hydraulic fracture and how are the shale plays evaluated.

Unconventional fields only produce hydrocarbons cost-effectively through stimulation treatments to large-scale, due to this, the determination of the mechanical properties of the formation and its variation along the same recover a greater importance in these "reservoirs" since these allow us to determine the degree of fracturability of the formation, select the optimal orientation of the wells and designing the fracture treatment. .shale formation modeling in a simulation through information acquired with seismic and well logs.

HOW TO EVALUATE A SHALE PLAY? Part B Emanuel Martin In the first part of “HOW TO EVALUATE A SHALE PLAY?" we've developed: Shale play features, Main properties to evaluate, Kerogen, Total Organic Content (TOC), Organic Matter Classification, Thermal Maturity Determination, Depositional environment, facies characterization and Mineralogical composition. Now we're going to develop: Mechanical

is required to know the values of porosity, water saturation, permeability, reservoir volume and the volumetric factor of the gas or oil; the Total Organic Carbon (TOC), thermal maturity, depositional environment, mineralogical composition and mechanical properties.

How to evaluate a shale play? Part A Emanuel Martin Introduction Shale formations constitute 60% of the rocks that make up the Earth's crust being only a small group of them containers of hydrocarbons. The necessary conditions to ensure that these rocks have generated and stored oil or gas is that they have abundant

WHERE IS THE GAS STORED? Author:  Emanuel Martin Gas in an unconventional field is found in shale which is a rock  rich in organic matter belonging to the family of the mudrocks with the distinctive feature of breaking easily in thin layers. It´s constituted by particles of fine grains that have one

WHAT IS HYDRAULIC FRACTURING? PART B Emanuel Martin In the first part of “Introduction to hydraulic fracturing" we've developed: What is hydraulic fracturing?, Which is the operation principle?, Operation of hydraulic fracturing, What form and direction can take the fracture?, Fracture orientation, Hydraulic fracture design, Selection between vertical, horizontal and multi-wells pad

What is hydraulic fracturing? part A

by Emanuel Martin - 1
Hydraulic Fracturing also known as fracking or fracing is a wells stimulation technique developed in 1947 by Stanolind Oil and aims to increase the drainage area and the performance of the same through the creation of fractures in the productive formation.

Since then its use, technology and development have been in continuous growth becoming a daily technique of completion of wells in formations of low permeability and high pore pressure or wells where the drainage area was damaged during the drilling or termination of the same. The combination of horizontal drilling with
