Schkade Production Company- Subsurface Investigation, Geologic Unit Evaluation and Fate & Transport Modeling
Not Completed Yet
A hydrocarbon and produced water seep was identified in a creek which traverses the site. The producer immediately terminated production operations at the site in accordance with RRC instructions. The seep was identified in the creek to the east of the suspect injection well. The RRC requested the producer initiate containment and remediation operations at the seep to manage the discharge of phase-separated hydrocarbons (PSH) and produced water into the creek and backflow to the injection wells. The producer deployed oil absorbent pads and booms and other equipment to manage the seep at the site.
Several plugged production wells completed in the 1940s on behalf of other producers are located at the site. Based on the available RRC documentation, each of these wells were drilled utilizing cable-tool drilling techniques and were plugged subsequent to completion due to an insufficient volume of crude oil for production or at a later date due to diminished production.
The producer re-entered select plugged cable-tool wells to evaluate each as a potential source of the seep. Ensolum personnel documented the plugging materials and depths of each material associated with each cable-tool well, collected PSH samples and produced water samples. PSH samples were submitted for paraffin (P), isoparaffins (I), aromatics (A), naphthalene (N), and olefins (O) analysis. PIANO analysis or “fingerprinting” is commonly utilized to evaluate the source and/or make-up of PSH samples. The water samples were submitted for cations/anions (potassium, chloride, sulfate, calcium, magnesium, sodium, nitrate as nitrogen, alkalinity, bicarbonate alkalinity and carbonate alkalinity) analysis to evaluate the likely geologic formation where the water originated.
Ensolum personnel also reviewed RRC UIC records, Texas Water Development Board records regarding formation waters, and Texas Society of Petroleum Engineers publications regarding formation water geochemistry to evaluate the potential source of the water.
Based on the laboratory analytical results, observations of pressure at select data points during the completion of investigation activities, site geology and the exposure of an artesian brine aquifer to the historic cable-tool production wells, a historic cable-tool well was identified as the likely source of contamination to the creek.
Petroleum Products Terminal Environmental Consulting Services
Not Completed Yet
The project site is an operating refined petroleum products terminal located in Fort Worth, Texas. During the completion of due diligence activities related to a real estate transaction at an adjacent property, petroleum hydrocarbons were identified in soil and groundwater as a result of a release from the pipeline manifold at the terminal.
Ensolum personnel were retained to further investigate the magnitude and extent of petroleum hydrocarbons in the on-site soil and groundwater, and to conduct response actions to mitigate on-site contamination and its off-site migration. Subsequent to the completion of investigation and groundwater resource classification, which included a Class 3 GW resource designation, a Remedy Standard B closure, utilizing a Plume Management Zone, was selected for the on-site affected area, and a Remedy Standard A closure was selected for the off-site affected area. To reduce the concentrations of chemicals of concern (COCs) in the off-site soil and groundwater to below the TRRP Tier 1 Critical Protective Concentration Levels, in-situ chemical oxidation was selected as the appropriate response action.
Due to the unique characteristics of the fractured, low-hydraulic conductivity, limestone formation, the selected reagent was delivered to the affected soil and groundwater utilizing gravity feed infiltration trenches. The formation was prepared for contaminant oxidation by inoculating the treatment area through the infiltration trenches with an alkaline oxidative de-ionizing solution, sodium percarbonate and sodium persulfate. This served as a wetting agent, de-ionizing clay platelets and optimizing aqueous reagent contact with contaminants. The pre-oxidation alkaline de-ionizing solution also serves as a persulfate catalyst (producing sulfate radicals).
Twelve to twenty-four hours after installing the initial oxidant blend, the treatment area was subsequently inoculated through the infiltration trenches using VeruSolve-HP™ aqueous reagent as a Surfactant-Enhanced In-Situ Chemical Oxidation (S-ISCO™) Coelution Technology™. VeruSOLVE-HP™ is a stabilized surfactant-cosolvent/oxidant combination effective for surgical destruction of source term contaminants. The stabilized surfactant-cosolvent/oxidant blend achieves Winsor Type I solubilization, where the contaminant is solubilized as a single-phase micro-emulsion and dissolution of constituents occur without mobilization. This allows for the destruction of the contaminants that are currently in a non-aqueous phase (i.e. the source term). The resulting redox reaction will occur over a very long period of time. Reaction kinetics are controlled, sustaining a highly oxidative environment for weeks. Extended persistence greatly increases the contaminant-oxidant contact occurrence, thereby producing very favorable results.
The initial treatment event reduced the concentration of benzene from 2.7 mg/L to 0.051 mg/L and MTBE from 120 mg/L to 2.5 mg/L in the off-site groundwater. A follow-up treatment event further reduced the concentrations to 0.006 mg/L, which was below the TRRP Tier 1 Critical PCL for a Class 3 groundwater-bearing unit.
Crude Transmission Pipeline Corrective Action
Not Completed Yet
Ensolum personnel provided environmental consulting services in association with a release of crude oil from a pipeline pump station. The scope included subsurface investigation, risk-based assessment, and remediation utilizing the Railroad Commission of Texas (RRC) Field Guide for the Assessment and Cleanup of Soil and Groundwater Contaminated with Crude Oil/Condensate From a Spill Incident and Texas Risk Reduction Program (TRRP) regulatory guidance. During initial spill response activities, soil was excavated at the release source and placed into treatment cells constructed on-site. The affected soil was treated using a balanced fertilizer to enhance biodegradation of the crude oil. Treated soil was periodically tilled for a period of three (3) weeks to increase oxygen availability and stimulate naturally occurring bacteria in the soil which metabolize organics including petroleum hydrocarbons. An interceptor trench was installed between the source area and a nearby tributary. Two (2) underflow dams and absorbent booms were installed within the tributary to restrict the flow of crude oil in the creek. A permeable reactive barrier wall was installed to reduce the mass and restrict the downgradient migration of petroleum hydrocarbon compounds detected in on-site groundwater. Activated carbon was injected into the subsurface and was amended with a sulfate-reduction mechanism (BOS-200®) to take advantage of both aerobic and anaerobic environments. BOS-200® is a blend of select nutrients, a cultured mix of bacteria (symbiotic facultative microbes) that are known petroleum hydrocarbon degraders, gypsum, activated carbon, and iron. Approximately 193,241 gallons (4,601 barrels) of crude oil have been recovered to date utilizing vacuum trucks and mobile dual- phase extraction units. DPE, also known as multi-phase extraction, vacuum-enhanced extraction, or sometimes bio-slurping, is an in-situ technology that draws a vacuum on the formation and removes contaminated groundwater, phase separated hydrocarbons, and hydrocarbon vapor from subsurface soil. Extracted NAPL and impacted groundwater are collected for recycling or disposal and extracted vapor is consumed by the normal combustion process of the engine. Ensolum is currently conducting groundwater monitoring to ensure plume stability and the effectiveness of the soil and groundwater response actions. Additional DPE events will be conducted at the Site prior to filing a restrictive covenant limiting the future use of the initial groundwater bearing-unit and requesting regulatory closure from the RRC.
