Let’s take a closer look at the fundamental fracking techniques and the technological advancements that have shaped the field.

Drilling and Well Preparation

The fracking process begins with drilling a well into the target rock formation. Initially drilled vertically, the well is then gradually turned horizontal to maximize contact with the reservoir rock. Steel casings are inserted into the well, ensuring stability and preventing contamination of surrounding formations. Cement is then injected between the casing and the wellbore to create a secure seal.

Fracturing Fluid Injection

Fracking relies on the injection of fluid at high pressures to create fractures in the rock, allowing the release of trapped hydrocarbons. The fracturing fluid, typically a mixture of water, sand, and chemical additives, is pumped into the well and forced into the rock formation. The pressure exerted by the fluid creates fractures, which are held open by proppants (like sand) to allow for the flow of oil or gas.

The technology used in fracking fluid has seen significant advancements over the years. One notable development is the use of slickwater, a type of low-viscosity fracturing fluid that enables better penetration into the rock and increases resource recovery. The composition of the fluid can vary depending on the specific geological characteristics of the target formation.

Horizontal Drilling and Multi-Stage Fracturing

Advances in drilling techniques have played a crucial role in the success of fracking operations. Through the use of horizontal drilling, wells can access a larger surface area of the reservoir, maximizing production. By extending the wellbore horizontally through the rock formation, operators can tap into more pockets of trapped hydrocarbons.

In conjunction with horizontal drilling, multi-stage fracturing has become a standard practice. This technique involves isolating specific sections of the wellbore using packers and perforating the casing at multiple intervals. Each stage is then hydraulically fractured, creating a network of fractures that extends further into the reservoir, enabling higher production rates.
