Oil Drilling Mud System Ethiopia|oil based drilling fluid types : distribution
The petroleum industry generates oily sludge both upstream and downstream, which can be categorized as floor sludge, tank bottom sludge, and refinery “three sludge” (Chu et al., 2023; Ramirez et al., 2019; Yu, 2022) (shown in Fig. 1).Floor sludge is a three-phase mixture of oil, waste fluid, minerals, and sediments resulting from blowouts, runoff, and fluid leakage .

For OBM cuttings, the system can reduce the OOC- oil on cuttings to 3~5%. For WBM cuttings, we don't recommend to use vertical cuttings dryer. The drill cuttings system can recycle the drilling fluids for reuse to save drilling cost. The drill cuttings system can reduce the volume of final cuttings to save cost of thermal operation.
The mud circulation system is at the heart of oil and gas drilling operations, playing a crucial role in the success and efficiency of drilling projects. In Ethiopia, the use of advanced oil drilling mud systems is essential for the extraction of oil and gas resources. These systems are designed to control the pressure, lubricate the drill bit, carry cuttings to the surface, and provide stability to the wellbore during drilling operations.
Mud logging is the process of monitoring and analyzing the drilling mud (also known as drilling fluid) and the geological formations encountered during the drilling of an oil or
Oil Based Drilling Fluids
Oil-based drilling fluids, also known as oil muds, are a type of drilling fluid that uses oil as the continuous phase. These fluids are commonly used in drilling operations where water-based muds are not suitable due to geological conditions or specific drilling requirements. Oil-based drilling fluids offer several advantages, including better hole stability, higher drilling rates, and improved wellbore integrity.
Oil Based Drilling Fluid Types
There are several types of oil-based drilling fluids used in oil and gas drilling operations in Ethiopia. These include:
1. **Invert Emulsion Fluids**: Invert emulsion fluids are oil-based drilling fluids where water is the dispersed phase and oil is the continuous phase. These fluids are commonly used in drilling operations with high temperatures and formations prone to hydration.
2. **Non-Aqueous Fluids**: Non-aqueous fluids are oil-based drilling fluids that do not contain any water. These fluids are used in drilling operations where water-based muds are not effective, such as in formations with high salinity or reactive clays.
3. **Synthetic Based Fluids**: Synthetic-based fluids are oil-based drilling fluids that use synthetic oils as the continuous phase. These fluids offer improved environmental performance and thermal stability compared to traditional oil-based fluids.
4. **Low Toxicity Oil Based Mud**: Low toxicity oil-based mud is a type of oil-based drilling fluid that is designed to minimize environmental impact while maintaining drilling performance. These fluids are used in environmentally sensitive areas or where strict regulations are in place.

Oily sludge is a type of hazardous waste containing a variety of toxic substances. The selection of surfactant is particularly important in the treatment of oily sludge by surfactant washing (Zhao et al., 2005). The effect of rhamnolipids on oily sludge separation was investigated (Zhou et al., 2013). A maximum petroleum hydrocarbon removal .Envorem’s innovative new technology uses a little-known property of water to process production sludges, cleaning the solids and recovering the entrained oil without generating emissions. The technology combines established techniques with hydraulic shock .
