  • effect of drilling fluid systems and temperature on oil mist and vapour levels generated from Shale Shaker

    Abstract:

    Workers in the drilling section of the offshore petroleum industry are exposed to air pollutants generated by drilling fluids. Oil mist and oil vapour concentrations have been measured in the drilling fluid processing areas for decades; however, little work has been carried out to investigate exposure determinants such as drilling fluid viscosity and temperature. A study was undertaken to investigate the effect of two different oil-based drilling fluid systems and their temperature on oil mist, oil vapour, and total volatile organic compounds (TVOC) levels in a simulated Shale Shaker room at a purpose-built test centre. Oil mist and oil vapour concentrations were sampled simultaneously using a sampling arrangement consisting of a Millipore closed cassette loaded with glass fibre and cellulose acetate filters attached to a backup charcoal tube. TVOCs were measured by a PhoCheck photo-ionization detector direct reading instrument. Concentrations of oil mist, oil vapour, and TVOC in the atmosphere surrounding the Shale Shaker were assessed during three separate test periods. Two oil-based drilling fluids, denoted 'System 2.0' and 'System 3.5', containing base oils with a viscosity of 2.0 and 3.3―3.7 mm 2 s ―1 at 40°C, respectively, were used at temperatures ranging from 40 to 75°C. In general, the System 2.0 yielded low oil mist levels, but high oil vapour concentrations, while the opposite was found for the System 3.5. Statistical significant differences between the drilling fluid systems were found for oil mist (P = 0.025),vapour (P < 0.001), and TVOC (P = 0.011). Increasing temperature increased the oil mist, oil vapour, and TVOC levels. Oil vapour levels at the test facility exceeded the Norwegian oil vapour occupational exposure limit (OEL) of 30 mg m ―3 when the drilling fluid temperature was ≥50°C. The practice of testing compliance of oil vapour exposure from drilling fluids systems containing base oils with viscosity of ≤2.0 mm 2 s ―1 at 40°C against the Norwegian oil vapour OEL is questioned since these base oils are very similar to white spirit. To reduce exposures, relevant technical control measures in this area are to cool the drilling fluid <50°C before it enters the Shale Shaker units, enclose Shale Shakers and related equipment, in addition to careful consideration of which fluid system to use.

  • Oil Mist and Vapour Concentrations from Drilling Fluids: Inter- and Intra-laboratory Comparison of Chemical Analyses
    Annals of Occupational Hygiene, 2011
    Co-Authors: Karen S Galea, Kjersti Steinsvåg, Kirsti Kruger, Alison Searl, Araceli Sánchez-jiménez, Torill Woldbæk, K. Halgard, Syvert Thorud, Laura Maccalman, John W Cherrie
    Abstract:

    Objectives: There are no recognized analytical methods for measuring oil mist and vapours arising from drilling fluids used in offshore petroleum drilling industry. To inform the future development of improved methods of analysis for oil mist and vapours this study assessed the inter- and intra-laboratory variability in oil mist and vapour analysis. In addition, sample losses during transportation and storage were assessed. Methods: Replicate samples for oil mist and vapour were collected using the 37-mm Millipore closed cassette and charcoal tube assembly. Sampling was conducted in a simulated Shale Shaker room, similar to that found offshore for processing drilling fluids. Samples were analysed at two different laboratories, one in Norway and one in the UK. Oil mist samples were analysed using Fourier transform infrared spectroscopy (FTIR), while oil vapour samples were analysed by gas chromatography (GC). Results: The comparison of replicate samples showed substantial within- and between-laboratory variability in reported oil mist concentrations. The variability in oil vapour results was considerably reduced compared to oil mist, provided that a common method of calibration and quantification was adopted. The study also showed that losses can occur during transportation and storage of samples. Conclusions: There is a need to develop a harmonized method for the quantification of oil mist on filter and oil vapour on charcoal supported by a suitable proficiency testing scheme for laboratories involved in the analysis of occupational hygiene samples for the petroleum industry. The uncertainties in oil mist and vapour measurement have substantial implications in relation to compliance with occupational exposure limits and also in the reliability of any exposure–response information reported in epidemiological studies.

  • Modeling of Oil Mist and Oil Vapor Concentration in the Shale Shaker Area on Offshore Drilling Installations
    Journal of Occupational and Environmental Hygiene, 2009
    Co-Authors: Magne Bråtveit, Kjersti Steinsvåg, Stein Atle Lie, Bente E. Moen
    Abstract:

    The objective of this study was to develop regression models to predict concentrations of oil mist and oil vapor in the workplace atmosphere in the Shale Shaker area of offshore drilling installations. Collection of monitoring reports of oil mist and oil vapor in the mud handling areas of offshore drilling installations was done during visits to eight oil companies and five drilling contractors. A questionnaire was sent to the rig owners requesting information about technical design of the Shaker area. Linear mixed-effects models were developed using concentration of oil mist or oil vapor measured by stationary sampling as dependent variables, drilling installation as random effect, and potential determinants related to process technical parameters and technical design of the Shale Shaker area as fixed effects. The dataset comprised stationary measurements of oil mist (n = 464) and oil vapor (n = 462) from the period 1998 to 2004. The arithmetic mean concentrations of oil mist and oil vapor were 3.89 mg/m...

    Journal of Southwest Petroleum University, 2007
    Co-Authors: Hou Yong-jun
    Abstract:

    A new type of Shale Shaker is presented,which is excited by three motor self- synchronously. With big exciting force and equipped with no mechanical transmission, and low noise, simple structure, convenient production and maintenance, it can be applied on the Shaker with big screening area especially. By building the mechanics model of this kind of Shaker,and using the Hamilton principle, the Self-synchronism qualification and stability condition of the Shaker system are built, and the conditions of the system can carry out uniform elliptical motion. Research results show that this kind of Shale Shaker can synchronously and steadily run when the self-synchronism qualification and stability condition are satisfied. So it is of bigger theoridical and engineering applying value.

  • WORKING PRINCIPLE OF A COMPLEX TRACK Shaker AND ITS COMPUTER SIMULATION
    Drilling & Production Technology, 2006
    Co-Authors: Zhu Weibing
    Abstract:

    In order to increase sieving efficiency of drilling fluid Shale Shaker, a new complex track Shale Shaker was put forward. On the basic kinetic principle of drilling fluid Shale Shaker, the working principle of the Shaker was introduced, and its motion was analyzed by computer simulation. The computer simulation results show that the points on the screen can obtain different line trace, the points at the entrance have larger throwing index, so it can accelerates the separating of solid and liquid, and the points at the exit have larger conveying speed, so the solid particle can slide out off the screen quickly, and it cannot pierce the screen. All these can increase its handling capacity and sieving efficiency. The action line of the exciting force should be moved toward the entrance and should not exceed its limit position, at the same time, the action line of the exciting force should be not moved toward the exit.

  • Experimental research and computer simulation on Shale Shaker fluid handling capacity
    Oil Field Equipment, 2004
    Co-Authors: Zhu Weibing
    Abstract:

    The fluid handling capacity for a Shaker is determined by both liquid and solid portions of the returning drilling fluid. The actual fluid flow capacity can be related to the fluid-only (no solids) flow capacity in terms of the solids loading factor K_w representing the effect of large-sized solids, and the solids/screen interference factor I representing the effect of near-sized particles. The fluid handling capacity model for a Shaker is derived as a function of solids conveyance speed, bit penetration rate, hole size, drilling fluid flow rate, particle size distribution of drilled solids and screen opening size. The results of lab test show that the model was of high simulation accuracy, it will be of significance to the select of Shale Shaker.
