WASTE INJECTION
A process of final disposal of hazardous and toxic waste resulting from the oil and gas exploration and exploitation activities comprising of Drilling Cutting, Oil Based Mud (OBM), Water Based Mud (WBM), Waste Completion Activity, Oily Viscous Fluid (OVF), Oily Waste Mud, and Oily Sand from Gathering Stations.
The waste is injected into a predetermined geological formation (injection target zone) by applying high pressure pumping to enable the waste gets into the target zone which is underneath an impermeable rock layer, thus to prevent the injected waste from rising up and out of the injection target zone that potentially impacts pollution to the ground water (shallow aquifer zone). In the long run, this waste disposal method will eventually reduce the affected surface area for waste disposal. The waste injection technology is proven as the most cost effective and environmentally acceptable method to dispose such hazardous and toxic waste especially for exploration drilling and workover operations, also exploration in a remote and sensitive environment area such as offshore where the drilling waste treatment and facility management are usually limited in these isolated areas. Waste Injection is one of the processes that develop an environmentally friendly and zero discharge technology in upstream oil and gas industry.

Waste Water Treatment Plant
Oil and gas drilling operations create quantities of contaminated water known as drilling waste water. Discharging wastewater from drilling sites may cause pollution and violate GOI Environmental Regulation Standards. Therefore, the wastewaters must be treated prior to discharge in the most economical and environmentally friendly method. It is possible to reduce and remove these drilling pollutants by using sequential combinations of different technologies.
1. Drilling Waste Water Treatment
2. Produced Water Treatment
Produced water is generated in the process of lifting oil and gas from water-bearing formations-typically sea or lake beds. As oil and gas is lifted to the surface, water is brought along with it. This water must be treated prior to di charge or re-injection. Oil and gas production activity produces significant volume of wastewater. This Produced water which has been in contact with minerals and organic rich coal has several constituents that are threatening to the soil and water quality. Till date, analysis of produced water from oil and gas has been focused on the organic and inorganic contents and less is learnt about the organic contaminants.
3. Water Treatment Injection Plant
Water is the largest by-product by volume in Oil & Gas industry, known as produced water. To improve productivity, produced water with specific quality requirements is injected into the well for secondary and tertiary recovery phase. Several treatment processes are required for produced water to be injected.
We provide recommendation on prudent Pattern Waterflood Planning & Strategy which covers design and field execution plan include source of water and engineering design. We also provide peer review / peer assist services on the GGR Study that has been conducted by client.
Sewage Treatment Plant Module
A sewage treatment plant is designed to treat and process raw sewage over different steps involving breaking, filtering, settling, controlled aerobic decomposition and chemical treatment. Sewage treatment plants collect, treat, and discharge wastewater, providing a service essential to environmental and public health. Without adequate treatment, sewage will leach into the environment and contaminate ecosystems.
Total Drilling Waste Management (TDWM)
Onshore oil drilling operations create quantities of contaminant known as drilling waste water and drill cuttings. Discharging waste water and drill cutting from well drilling sites may cause pollution and environmental law. Drilling waste waters and drill cuttings contain many unwanted chemicals, sediment, mud, foam, and other additives that can pollute a stream or river, wetlands, channel or fresh waters wells. Drilling waste waters and drill cuttings are recognized as pollution and can degrade water quality supporting fish and aquatic life. The waste waters must be treated prior to discharge in the most economical and environmentally friendly method, while drilling cuttings need to be processed onsite to be easily transported for further treatment in waste management facility.
Soil Remediation
Customized treatment solutions for soil remediation according to different contaminations and actual situation of brownfield. Crude oil contaminated soil can be processed rapidly and economically either ex-situ or in-situ. Ensure that the remediated sites meets the relevant standards, eliminates or reduces environmental risks, and restores the utilization value of the land.
Bioremediaton method can be used to neutralize pollutants by stimulating the growth of indigenous organic-degrading flora, mainly applied for low concentration pollutant such as TPH.
Filtration
Cost effective and efficient filtration systems solution for completion fluid filtration and workover fluid completion for every completed well. Contamination of the formation with particles can occur during wellbore clean up, perforating, fracturing, acidizing, workover, water injection, and gravel packing as well. Contamination reduces production and shortens the life of producing well.
Filtration completion, work over or wellbore clean up fluid is to prevent the downhole contamination of the formation. Therefore, all fluids used during completion of an oil and gas producing must be free of dirt particles.
