Fresh Water Sediments

Many scientific principles go into finding oil and gas, and  Weatherby Energy has expertise and knowledge in the science behind drilling. For those thinking about investing in Weatherby Energy or simply curious about what Weatherby Energy does, it can be interesting to learn about some of the science behind the process of how oil or minerals get made and of how they are found. To better understand this, it is helpful to have a background in fresh water sediments and geology. Weatherby Energy provides an overview below.


Understanding Fresh Water Sediments and Geology


Oil and gas can be made from ancient organisms through a complex natural process:

  • Organic matter living in lakes dies and falls to the sediments at the bottom and is covered with more sediment before it has a chance to decay.
  • As more sediment lies on top of the buried organic material, the temperature and pressure increases.
  • When the temperature reaches 150 degrees F, the organic material begins to form hydrocarbons.  The organic material has to be at least 7000 feet below the top of the sediment for this reaction to occur.
  • Over time, the gas and oil will rise because it is less dense than the surrounding material.  If a barrier does not stop it, it will seep out onto the surface of the land.  Usually the oil and gas migrates into permeable layers of rock, are stopped by a barrier, and form reservoirs.


There are three types of depositional environments where the organic masses are deposited into the sediment. They include terrestrial, lacustrine, and marine.  Terrestrial is land and marine refers to the ocean floor.  Lacustrine refers to the sediments at the bottom of lakes, which may be salt water, brackish, or fresh water, but is usually used to refer to fresh water lakes.


Sediment is deposited into these lakes from rivers and streams.  Most of the organic matter that has turned to oil came from the algae in those lakes.  Since sediment is slow to accumulate in lakes, this leads to the source rock or shale being very high in concentrations of organic fuel.


Oil Shale

Oil shale is a type of rock that is made of sediments through this natural process. It contains a substantial amount of kerogen, which is organic matter that has been trapped in sediments and over time with heat and pressure been changed into oil and gas.  This kind of rock is referred to as source rock, as it has a source of oil or gas.  Shale can be categorized by either what is in it, like clay or minerals, or where it was made, which is its depositional environment.


Shale oil does not substitute for crude oil in every way but has many useful applications.  It can be incinerated like coal to fuel steam turbines and used in thermal power plants.  Because it often has more nitrogen, oxygen, olefins, sulfur, or arsenic than crude oil, it would take more refining to use it as crude oil.  It is better suited for making diesel and jet fuel and kerosene.  Some of the products it may be used to make include: resin, glue, carbon black, cement, bricks, fertilizers, glass, and medicines.  Some oil shale contains ammonia, soda ash, alumina, and uranium.


Weatherby Energy is an expert in understanding these and other scientific principles behind finding oil and gas.
