  • Gas injection to increase recovery from the Bakken formation

    The Bakken formation, in the Williston Basin, has tremendous oil reserves estimated to be in the hundreds of billions of barrels. During the last decade, the Bakken has been rapidly developed with advances in horizontal drilling and improved multi–stage hydraulic fracturing. The primary recovery factor, however, has remained very low, around 5%–10% due in part to the extremely low permeability. ...

  • EPA mandates proper refrigerant gas recovery processes

    New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • Optimization of a Sulfur Recovery Unit

    Prior to Suncor’s purchase of the Spirit River facility, little attention was given to the LO-CAT unit. In general, over injecting chemicals into a LO-CAT unit will not result in operating problems, just higher than required operating costs. Consequently, in remote gas plants such as Spirit River, it is sometimes difficult to convince operators to change operating conditions if the unit is not ...

  • Enhanced liquid recovery by carbon dioxide sequestration in gas/condensate reservoirs

    CO2 sequestration in a depleted gas/condensate reservoir could be a viable option due to the economic benefits associated with the enhanced liquid recovery. According to previous laboratory investigations, CO2 may be superior to methane (CH4) or nitrogen (N2) ...

  • Mercury recovery from industrial waste and toxic residues of natural gas drilling

    econ's client in the east of Germany is one of the few specialised companies in Europe for the treatment of mercury contaminated waste. Typical input material for this type of treatment is sludge from the natural gas industry or other residues from chemical processes, i.e. contaminated filter cake from waste water treat-ment. Among their most important clients are Shell, ExxonMobil, Wintershall ...

  • VaporRemed helped in recovery of pets

    We recently converted our oil boiler to gas and the heating crew could not remove the half-full, 250-gallon oil tank until one week later. Hence, we had an open fuel oil tank (the pipes were removed) and strong oil fumes inside our home. As a result, our dog and cat became ill within a few hours. Upon receiving and spraying the VaporRemed, the fumes quickly disappeared and the animals recovered. ...

  • H2S Oxidation and Sulfur Recovery

    Lubrizol’s facility in LeHarve, France produces a lube oil additive via a batch reaction that uses elemental sulfur as a reactant and produces H2S as a byproduct. Lubrizol selected Gas Technology Products LO-CAT® II Hydrogen Sulfide Oxidation Process to sweeten H2S emissions and recover sulfur. The LO-CAT II system was chosen for its ability to handle the process variation in H2S ...

  • Power Positive Resource Recovery

    Using laws of thermodynamic analysis to evaluate the energy and power characteristics of wastewater and beneficial uses of biogas offers greater insight into best business practices and what is achievable. Growing numbers of waste-water treatment plants (WWTP) are striving to produce more power onsite. In recent years, there’s even been a race among WWTP operators to see who can ...

  • Maximizing Energy Recovery through Digester Gas Management System Enhancement

    ABSTRACTAdvanced anaerobic digestion practices and maximum energy recovery call for a digester gas system that reliably allows for complete biogas collection and utilization. This paper will describe the planning, design, and construction of a new digester gas management system at the East Bay Municipal Utility District’s (District) Main Wastewater Treatment Plant. The need for an upgraded ...

  • Case study - Product Recovery (France)

    Product recovery of cobalt and lithium oxides This installation was designed to enable the customer to quickly change elements between production runs - thereby not only does this save time and money but also maximises operational efficiency during product recovery. To avoid filtrate 'hang ups' and potentially costly cross-contamination, all internal surfaces are ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • An evaluation of post-hurricane recovery of oil and gas platforms destroyed in the 2004-2005 Gulf of Mexico hurricane seasons

    Hurricanes Ivan, Katrina, and Rita passed through the Gulf of Mexico during 2004 and 2005 and resulted in the largest number of destroyed and damaged offshore structures in the history of Gulf operations. In the final official government assessment, a total of 120 platforms were destroyed and over 183 structures were identified as having extensive damage. One deepwater floating structure, ...

  • Common challenges relative to the use of Decanter Centrifuges for barite recovery in the oil & gas industry

    When centrifuges are properly deployed, they can have dramatic effects on drilling performance. In fact, without them, many of the advances made in drilling would not have been considered achievable. Classically, we believe that centrifuges can achieve two common goals: Reduce the content of drilled fines, specifically colloidal solids, and Perform barite recovery in order to reduce ...

  • Production performance of water alternate gas injection techniques for enhanced oil recovery: effect of WAG ratio, number of WAG cycles and the type of injection gas

    Production performance of a water alternate gas injection (WAG) method has been reported for the effect of several operating parameters, such as, WAG injection cycles, viz. , single cycle WAG and five-cycle WAG and the tapered WAG at the reservoir conditions of 120 ° C and 230 kg/cm 2 for hydrocarbon gas and CO 2 gas. It is observed that the number of ...

  • Drilling Muds and Drill Cuttings Recovery for Beneficial Reuse

    Drilling Muds Drilling mud, also known as drilling fluid, is a vital component of the drilling process. It helps in the process of drilling boreholes into the earth where holes are required for extraction of oil and gas, core sampling and various other purposes. It is broadly of three types, including water-based, oil-based, and synthetic-based. Among all of these, synthetic-based muds ...

  • Improving performance of a gas stripping-based recovery system to remove butanol from Clostridium beijerinckii fermentation

    The effect of factors such as gas recycle rate, bubble size, presence of acetone, and ethanol in the solution/broth were investigated in order to remove butanol from model solution or fermentation broth (also called acetone butanol ethanol or ABE or solvents). Butanol (8 g L–1, model solution, Fig. 2) stripping rate was found to be proportional to the gas recycle rate. In the bubble size range ...
