Colorado Produced Water
Colorado Produced Water Oily Wastewater Treatment Jar Test Colorado Oil Patch This sample is representative of the produced water from the Colorado oil patch region. The sample contains free and emulsified oil, dirt, and water. The water is very saline (high in dissolved solids especially chlorides and sodium) which is common in this industry. The sample pH was measured to be 6.8. ...

BP Schiehallion - produced water degasser
Client: BP Schiehallion - UK In July 2004 BP was required to take its produced water degasser on the Schiehallion FPSO offline for essential upgrade work. Without a replacement technology BP potentially faced a production shutdown during repairs. CETCO offered its CrudeSep® technology to BP as a temporary degasser vessel. In addition to oil and solids removal the CrudeSep® also acts as an ...

Shell - produced water treatment
Client: Shell Auk CETCO Oilfield Services mobilised an 18” diameter twin vessel CrudeSep® test skid and a RFV 3000 adsorption skid comprising of dual sock filter pods and two vessels holding adsorption media canisters. The CETCO equipment was tied in downstream of the existing WEMCO and hydrocylones and successfully treated produced water at a variety of rates. Samples were taken from a variety ...

Electrochemical removal of sulfate from petroleum produced water
Petroleum produced water (PPW) is a waste-stream that entails huge cost on the petroleum industry. Along with other suspended and dissolved solids, it contains sulfate, which is a major hurdle for its alternative use intended toward enhanced oil recovery. This study proposes a two-step process for sulfate removal from PPW. A synthetic PPW was designed for the study using response surface ...

Produced water at UGS Dolni Dunajovice
Water is the main contaminant of natural gas. Mostly, it is a natural element of a reservoir content. When dry gas is injected into a reservoir, it absorbs volume of water there. Together with water, it absorbs hydrocarbons, which can be natural elements of the reservoir or of artificial origin and contaminants which were injected in to the reservoir with natural gas. During a withdrawal, this ...

Creating a diversion - creating a bypass to treat produced water
ProblemAn oil company needed to repair its water treatment equipment without curtailing oil production. SolutionCETCO Oilfield Services created a bypass that allowed the oil company to continue operations during repairs. Here’s what we did: Identified an accessible section of piping upstream of the equipment to be repaired. Made 4 hot-tap connections within the identified piping section. ...

BP Petrojarl Foinhaven - produced water treatment
Client: BP/PGS Petrojarl Foinaven - UK CETCO were approached by BP/PGS regarding potential fluids handling problems on the Petrojarl Foinaven FPSO when bringing on two new wells during September 2001. CETCO mobilised a RFV 4000 DF Adsorption Skid containing CETCO’s patented CrudeSorb® media to treat the oily water phase of the well returns for discharge directly overboard. During a two week ...

What is Produced Water?
Produced water is a byproduct brought to the surface during oil and gas exploration and production. Sometimes it is called formation water, brine, or saltwater. It is typically brackish and comes from underground formations, either from zones adjacent to the oil and gas, or from the same zone as the hydrocarbons. In some oil and gas operations, the produced water results from injecting clean ...

Produced Water Case Study
Challenge Managing the increasing volumes of produced water associated with oil & gas production as well as sourcing water for operations is becoming more challenging for E&P companies. Handling oily wastewaters with high and variable contents of O&G and TSS requires complex and costly treatment trains with conventional technologies. To evaluate akvoFloat ’s capability to ...

A study on the quantities and potential use of produced water in southern Iraq
This paper presents the results of an analysis of volumes and chemical composition of produced water (PW) accompanying oil production from five of the largest oilfields in the world situated in Basrah, Iraq. PW is potentially a valuable water resource particularly there where the ramp up of oil production puts further strains on water and the environment in an area already having severe water ...

Produced water filtration optimization case study
Pentair Porous Media has worked with a major global oil & gas producer to optimize the performance of the filtration and separation at their United States mid-continent operations located in the Wind River Basin of Central Wyoming. Their operations cover more than 42,500 net acres in Wyoming. Net gas production averages greater than 100 MMSCFD from multiple formations ranging in depth from ...

Produced water treatment from a to Zinc - reducing levels of Zinc in a produced water stream
Problem At vast depths, the ocean floor consists of layers of decaying plant and animal matter, containing chemicals like sulphate and zinc, which has built up over the years. When operators are drilling, the matter is disturbed and the various chemicals are released into the water. Since the mid 1980’s the pace of exploration, production, and development in the deep waters of the Gulf of Mexico ...

Talisman - produced water treatment to <30 ppm
Client: Talisman Buchan Alpha - UK Following successful trial work, CETCO supplied a single 48” CrudeSep® vessel skid to treat produced water for discharge overboard. Talisman then purchased a second 48” CrudeSep vessel skid to further reduce its overboard oil in water discharges in line with regulations. CETCO’s CrudeSep system treated approximately 12,000 bbls/d of produced water on the ...

Brazil Containerized Leachate Treatment Project
Jiarong has applied its high concentrate technology overseas to help Customer in Brazil to reduce the wastewater discharge and the produced water was fully met the local discharge standard. Project feature: The design treatment capacity is 250m3/d, with an operating capacity of ...

Water treatment technology for produced water
Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

Toxicity assessment of oil field produced water treated by evaporative processes to produce water to irrigation
During the productive life of an oil well, a high quantity of produced water is extracted together with the oil, and it may achieve up to 99% in the end of the well's economical life. Desalination is one of mankind's earliest forms of saline water treatment, and nowadays, it is still a common process used throughout the world. A single-effect mechanical vapor compression (MVC) process was tested. ...

Decision making for produced water management: an integrated multi–criteria approach
Developments of effective produced water (PW) management strategies pose a challenge to the offshore petroleum industry. In this study three PW minimisation systems: down hole oil–water separation (A1), chemical water shut off (A2) and mechanical water shut–off (A3) were evaluated based on fourteen pre–selected criteria from environment, cost and technical point of view. Fuzzy ...

Can Produced Water Be Safely Reused?
The oil and gas industry produces billions of gallons of heavily contaminated wastewater that could be recycled into a valuable resource The oil and gas industry is an extremely water-intensive one. Millions of gallons are used during the hydraulic fracturing process, and billions of gallons of wastewater are generated from these activities. Around 250 million barrels of produced water are ...
