  • Patent number: 9327806
    Abstract: Provided is an arctic drill ship in which a weather tight structure protecting a drill floor and a drilling work area from outside air is coupled to a side strake around the drilling work area. It is possible to economically and easily manufacture the weather tight structure which minimizes the influence of outside air on the drilling operation in the polar regions, and it is possible to efficiently support the hull longitudinal strength and the weather tight structure with the use of the side strake structure solely. Therefore, a structure which may cause a disturbance in the drilling work area is minimized, and it is unnecessary to install a separate structural reinforcement part for a drilling workspace in the polar regions. In addition, the drilling workspace in the polar regions can be effectively ensured, and a spatial limitation in an upper portion of a moonpool can be solved.

  • Patent number: 9266254
    Abstract: A water/slurry containment device for core drilling can contain and allow water/slurry to be extracted while the coring is occurring rather than allowing a puddle to form with more extensive cleanup required afterward. The device contains the water/slurry mix so that none escapes the confines of the device, so that water can be used in the core drilling. Water is essential to the life of the diamond coated bit and it keeps dust and noise to a minimum. The device includes a base plate with a collector ring that can rest on a surface to be core drilled. A notch can be cut in the collector ring and/or base plate to allow water and slurry to be removed from the device while core drilling.

    Abstract: A system for treating spent/used Oil Based Drilling Muds (OBM's) to recover High Gravity Solids (HGS) for further reuse and to separate the invert emulsion from the Light Gravity Solids (LGS) with good characteristics also for further reuse. Separated LGS is processed to extract the remaining oil in order to render an environmentally safe solid fraction. The overflow of a screening or centrifugation of spent OBM enters a reactor where reagents are added and mixed to control the oil/water ratio of the recovered emulsion and to reduce the LGS concentration. A catalyst is added before adding a final reagent that initiates the reaction. Upon centrifuging the reacted mix, the recovered emulsion is the overflow and a thin layer of LGS forms slightly below the emulsion. The underflow of this separation is further sedimented by gravity and the phase dispersant layer is decanted and sent for reuse.

  • Patent number: 7681633
    Abstract: A well bore fluid recovery system and method is disclosed for recovering a column of well bore fluid within a stand of casing before cutting the casing. The recovery system relates to a system for preventing fluids from being spilled when casing is being finished for a well bore. After being run the casing must be cut and finished at an appropriate level to install rig equipment such as blow out preventers along with other equipment. However, because of earlier operations, the entire length of casing is typically filled with drilling fluid. Depending on conditions, the length of casing which is to be cut and removed may therefore over a 100-foot (27.4 meter) column of drilling fluid therein. The drilling fluid in this section must be properly drained before the casing is cut and removed.

  • Patent number: 7581601
    Abstract: A system to re-inject drill cuttings slurry into a well formation for the storage of the cuttings. The system may include a pressure containing conduit that creates a flow path to an annulus within the well formation. The system may include an injection inlet, a drilling guide base, an injection adapter having a circular gallery, an injection mandrel having at least one injection port, and an annulus created between the injection mandrel and an inner casing. The slurry may be injected into the annulus while still drilling the wellbore. The location of the injection inlet may be positioned relative to the circular gallery of the injection adapter such that a cyclone effect is created within gallery minimizing erosion due to the flow of the slurry. The injection mandrel may be adapted to allow the passage of drilling mud to a downhole drilling location while injecting slurry into the casing annulus.

  • Patent number: 7575073
    Abstract: A fluid handling system for drilling cuttings utilizes a constant and gravity managed liquid level between a substantially atmospheric separator and a shale shaker to maximize fluid residence time within the separator and ensure substantially all of the gas entrained in the cuttings is evolved and passed to a flare thus preventing evolution of the gas at the shale shaker. Solids from the separator are combined with liquid recirculation from and returning to the shale shaker. Optionally, a vacuum degasser is positioned between the separator and the shale shaker and separated gases are passed from the degasser to the flare. This method and system is particularly applicable to balanced, underbalanced and air drilling operations where the flow of gas is intermittent and unpredictable.
