Physical characteristics and aquatic settlement properties of offshore drill-cuttings.
Drilling operations have been proven to cause pollution in the marine environment. From these environmental concerns, regulations and drilling muds evolved towards more environmental orientated operations. The environmental impact assessment is now compulsory and made public. In order to carry out …

Sustainable treatment of oil contaminated waste: oil-based mud (OBM) drill cuttings and soil.
Environmental pollution from oilfield drilling waste poses potential hazards which can lead to ecological imbalance. The predominant pollutant from oilfield waste is petroleum hydrocarbons. Some effects of petroleum hydrocarbon contamination in soil include loss of nutrients, reduced fertility, …

Feasibility of sustainable recycling of drill cutting as additive in flexible base
The management of drill cuttings, a byproduct of oil and gas drilling, presents significant environmental challenges. In Texas, millions of cubic yards of drill cuttings have accumulated, raising concerns over long-term storage and disposal. At the same time, the state consumes approximately 3.7 …

Aspects of energy requirements for rock drilling
… A detailed study of laboratory rotary-percussive drilling in a wide range of rocks under different conditions, with the collection of drill cuttings and measurement of the drill parameters. The correlation of drill parameters with rock indices by energy concepts and the developed empirical …

GEOCHEMICAL CHARACTERIZATION OF THE BONE SPRING FORMATION, DELAWARE BASIN, USING CHEMOSTRATIGRAPHY AND INTEGRATED PETROPHYSICS
… logs are sporadically collected, whereas drill cuttings are available from most wells. For this study, XRF elemental data derived from drill cuttings collected at 30 – 60ft (9 – 18m) intervals have been compared to wireline well logs. XRF measurements were categorized using hierarchical …

IDENTIFYING SALT SUTURE ZONES AND LITHOLOGICAL CHANGES OF THE LOUANN SALT IN THE GULF OF MEXICO BASIN, LA. U.S.A.
… wells (Puma 2(w), Puma 3, and Panther). Using drill cuttings, X-ray fluorescence (XRF), inductively coupled plasma mass spectrometry (ICP-MS), X-ray diffraction (XRD), well-log data, and 3D seismic interpretation, the study analyzed salt composition and suture formation. Results show the salt …

Admicellar Polymerization to Compatibilize Calcium Carbonate With Oil-Based Drilling Mud
… agents like calcium carbonate (CC) are added to drilling mud to improve mud properties and performance during oil and gas drilling operations. Oil-based mud (OBM), a more preferred drilling mud, being hydrophobic is particularly non-compatible with hydrophilic CC. This work explored an …

Reservoir characterization of the Aldrich, Aldrich NE and Keilman North fields, Ness County, Kansas for potential exploration of sub-Mississippian formations
… an “open-hole” completion method. This precluded drilling deeper horizons. Although modern drilling and completion techniques allow drilling through and isolating water-drive reservoirs like the Mississippian, very few deep exploratory wells have been drilled in Ness County. Wells that penetrate …

Patterns and mechanisms of heat transport in the northern Denver Basin Nebraska, South Dakota and Wyoming
… core samples and 60 unconsolidated samples from drill cuttings, yielding a harmonic mean thermal conductivity value of 1.52 ± 0.91W m-1 K-1 for the stratigraphic column of the study area. A total of 929 thermal gradient values compiled from several databases were incorporated with thermal …

Development of an innovative and environmentally sustainable solid waste stream treatment process.
… tank oil bottoms from crude oil storage tanks c) drill cuttings from oil and gas exploration and d) Oil based drilling muds . The petroleum sludge wastes typically are water-in-oil emulsion that are stabilised by fine solids. The Hazardous Waste Directive classifies oily sludges and oil …

Multi-Scale Nanoindentation For Characterization Of Oil Shales
… Tuscaloosa Marine Shale samples (retrieved from drilling mud). For the Woodford Shale, an average of twenty-five indentations was considered. Likewise, for the Tuscaloosa Marine Shale, eighty indentation tests were completed for each sample depth for an end result of 1,200 indentation tests for …

Geothermal reservoir characterisation using automated mineralogy; implications for CO2 sequestration
Drill cutting analysis provides a cheaper and less time consuming alternative to the collection of core samples during geothermal exploration, although providing less lithological detail than cores. In this study,drill cuttings collected from the Nesjavellir geothermal field in Iceland were …

Modeling Storage and Flow of Fluids in Shale Reservoirs
… expanded rapidly through the application of new drilling and completion technologies, particularly horizontal wells completed in multiple hydraulic fracture stages. While these technologies play a critical role enabling economical production from these resources, uncertainty in the understanding …

Demulsification and recycling of spent oil based drilling fluid as nanofiller for polyamide 6 nanocomposites.
Spent oil-based drilling fluid and cutting wastes are global liabilities due to their hazardous hydrocarbon content, which impacts negatively on flora, fauna, and global carbon footprint. The formulation of two demulsifiers to ensure chemically-enhanced phase-separation of this waste into oil, …
