What is conventional and unconventional oil and gas
I am increasingly being asked by clients and other organizations as to whether a reservoir is conventional or unconventional shale, and this raises an important question when it comes to planning and regulations within certain regions. The answer to this question is not as clear cut as it may seem. Unconventional oil and gas Conventional versus unconventional oil and gas . The oil and gas industry use a range of techniques to extract oil and gas from underground reserves. Conventional oil and gas reserves can be exploited by drilling a well, with oil or gas then flowing out under its own pressure. Context. Unconventional oil resources are typically more expensive to produce than conventional oil, often in the $40-$80/barrel range for production.However, the production of unconventional oil is increasing due to rising demand for fossil fuels and falling reserves of conventionals.. The unconventional oil “revolution” has drastically changed the world energy landscape. Figure 1b: Liquid-Fuel Supply (Unconventional Oil/Business-as-Usual) million barrels/day oil-eq.

Unconventional oil and gas refers to the oil and gas resources which cannot be explored, developed and produced by conventional processes just in using the natural pressure of the wells and pumping or compression operations. These unconventional crude oil and natural gas are trapped in the pores of sediments rocks called shale. Comments

What is "Unconventional" Oil and Gas? "Unconventional" oil and gas is not chemically different from "conventional" oil and gas. The distinction stems from their position underground or from the unusual nature of their reservoirs. These conditions require the use of new, often complex, extraction methods. Below is a simplified summary of these oil and gas resources. Conventional oil or gas comes from formations that are "normal" or straightforward to extract product from. Extracting fossil fuels from these geological formations can be done with standard methods that can be used to economically remove the fuel from the deposit. Conventional oil and gas refers to petroleum, or crude oil, and raw natural gas extracted from the ground by conventional means and methods. Comments In practice conventional oil and gas, or the term of conventional resources , applies to oil and gas which can be extracted, after the drilling operations, just by the natural pressure of the wells and pumping or compression operations. Conventional Oil Versus Unconventional Oil. Historically, the exploration and production of oil and natural gas focused on the sources that were easiest to access. Conventional oil wells are vertical shafts into pools of oil and gas that are under pressure, making them easy to bring to the surface. Unconventional more refers to the wellbore geometry and zone where the oil is contained. Conventional oil is the "low hanging fruit" where the well is verticle and the payzone flows with little restriction into the well bore.
