Definitions

  • This invention concerns method and apparatus for transporting and storing materials, especially oily particulate materials.
  • Processing facilities are often remote from the drilling location, requiring the cuttings to be transported to the process point.
  • a common practice is to collect the cuttings as they are removed from the solids control equipment in containers for storage and transport. Such containers are typically industrial skips or purpose designed units. Once filled the containers will be loaded by forki ft or crane onto trucks for road transport (if the location is onshore; , and if the location is offshore the containers will be loaded by crane onto a supply boat for transport to the dockside for unloading by crane to road transport, or directly to the processing station, if this is at the dockside.
  • the container must be unloaded, cleaned, inspected, repaired if damaged and suosequently returned for refilling at the drilling site.
  • the movement of drill cuttings using this method thus involves significant investment in containers and handling equipment, is slow, manpower intensive, and can be prone to accidents occurring.
  • the contaminated mud no longer suitable for recycling on the rig, is pumped into the tanks of the supply vessel and the latter conveys the spent mud to the shore based reprocessing facility from which high quality mud can be recovered for transfer once again to the rig via the supply vessel .
  • the mud system is essentially a closed loop system when taking into account the shore based reprocessing facility.
  • the present invention seeks to provide an improved method for conveying cuttings at the rig site between the rig and the transport means, between the transport means and storage at the processing location, and from storage at the processing location to the processing facility.
  • the invention also provides an improved method for storage of cuttings both at the well site, during transport and at the processing location.
  • solids generated during a drilling process are separated from the drilling fluid, and mixed with a carrier fluid to form a slurry to allow the mixture to be pumped along pipes.
  • the cuttings may be reduced m size prior to, during, or after slurrymg.
  • the solids should be below 5mm in diameter, as larger particulates are more difficult to maintain in suspension in a slurry. However they should not be significantly reduced below that size since smaller solids are more difficult to separate from the carrier fluid at the processing location, and when separated tend to carry forward a larger quantity of liquid/drilling mud and/or carrier fluid, due to the increased surface area of small particles compared to that of larger particles .
  • the slurry is typically between 25 and 70% by volume, solids concentration.
  • the slurry may be stored before and/or after transportation from the drilling site, and in accordance with a second aspect of the invention the slurry is frequently agitated during storage to prevent settlement occurring.
  • the slurry is conveyed from a drilling site to a processing site at which the cuttings are separated from the carrier fluid, and the carrier fluid may be returned to the drilling site for re-use.
  • the slurry may be conveyed to the processing site in bulk using road transport alone in the case of shore based drilling and processing sites, or by ship (and road transport if required) , if the drilling is offshore.
  • the slurry may be stored at the processing site before processing.
  • the carrier fluid may be returned in bulk to the drilling site using similar transportation means.
  • the slurry is to be stored in a tank preferably the tank includes agitation means to maintain the solids in suspension.
  • any storage tank on any transportation means includes means for achieving the slurry agitation.
  • apparatus for treating solids by-products from a well drilling site which includes well drilling means, drilling mud storage means, pump means for pumping mud downhole, means for collecting mud returning from downhole, solids separation means for removing solid material including drilling cuttings from the recovered mud, and mixing means for mixing the mud recovered with fresh mud for pumping downhole again, the said apparatus comprising means for mixing a carrier fluid with the recovered solids to form a slurry, storage means for storing the mixture of recovered solids and carrier fluid in the form of the slurry, agitation means for maintaining the solids in suspension whilst stored, and means for transferring the slurry from the storage means to a container for transfer to a solids processing site.
  • the solids separation means includes filtering means for removing from the solids particles larger in size than that which will reliably remain in suspension in the chosen carrier fluid.
  • the cuttings may be separated from the drilling mud during the drilling of the well using conventional solids separation equipment .
  • Cuttings collected from the solids control equipment either may be mixed with carrier fluid to form a slurry in or near the separation equipment, or may be conveyed to a remote point for slurrying.
  • the carrier fluid should support the solids m suspension without the need for agitation of the fluid, but should be pumpable or flow by gravity when required.
  • the carrier fluid may be of a lesser specification.
  • the carrier fluid is such as to prevent the cuttings becoming exposed to free water with which the cuttings could react .
  • carrier fluid may be oil, viscosified oil, oil based drilling mud, synthetic oil based drilling mud, or any other fluid that will maintain solids in a stable condition and will support the solids in suspension as a slurry.
  • the carrier fluid is thixotropic - that is its viscosity is greater when it is stationary than when flowing.
  • Drilling mud is generally thixotropic but the thixotropic properties of ordinary drilling mud may not be sufficient to guarantee the suspension of larger sized particles, and where this is the case a carrier fluid is formed by adding to normal drilling mud additional viscosifying and/or gelling and/or emulsifying and/or oil wetting agents, so as to produce the required additional thixotropic and other desirable properties of the carrier fluid.
  • the thixotropic properties of ordinary drilling mud may be enhanced by the addition of a packer fluid such as Kenex packer fluid as employed in pipeline bounding sleeves to prevent (or reveal in the event of) , damage to pipelines where the latter extend below roadways and the like.
  • a packer fluid such as Kenex packer fluid as employed in pipeline bounding sleeves to prevent (or reveal in the event of) , damage to pipelines where the latter extend below roadways and the like.
  • any so-called packer fluid which is added is compatible with drilling mud, so that if traces of it become mixed with mud which is subsequently to be pumped downhole, serious problems do not arise.
  • the step of reducing the size of the solids may be followed by screening or solids classification to remove and recycle any oversize particles, so that only the maximum size of particle which will remain in suspension in the given carrier will remain in the slurry.
  • Classification may be achieved by simply filtering for size, and if appropriate returning oversize particles to the size reduction step in the process from where they can be once again supplied to the classifying stage.
  • an enhanced drilling mud as the carrier fluid is particularly advantageous in the case of offshore drilling rigs to which consumables are supplied by ship and from which byproducts such as oily cuttings are transported by ship back to a shore based cuttings processing facility where the oily cuttings are cleaned for landfill or other legitimate disposal.
  • a mud based carrier the same tanks as are employed for transporting fresh supplies of basic drilling mud to the platform can be used as the transport medium for conveying the slurry of cuttings from the rig to the shore based cuttings processing facility, provided that all of the ingredients added to the basic drilling mud to form the slurry are compatible with ordinary drilling mud and if not wholly removed from the mud before the litter is reused, will not affect the downhole characteristics of the mud.
  • the invention obviates the need to transfer containers from shore to rig and vice versa, and enables the storage tanks on the supply vessel which on the journey from shore to rig are filled with fresh drilling mud, to be filled with the carrier fluid and cuttings slurry for the return trip.
  • the slurry can be rapidly pumped from the rig to the ship and from the ship to shore. This means that the rig mounted crane is not tied up for long periods of time shifting containers from ship to rig and vice versa, as is required using conventional solids treatment methods and the hazardous storage of containers full of cuttings on the deck of the rig is also obviated.
  • the slurry of cuttings and carrier fluid of course has to be stored on the rig, but since it is a fluid which can be pumped, the storage means can comprise tanks at a low level on the rig or in an adjoining pontoon, to which the slurry is supplied either under gravity or with pumped assistance, and from which the slurry can be pumped via a pipeline to the supply vessel for the return trip to the processing facility on the shore.
  • the stability of the rig is therefore significantly improved since the weight of the stored slurry can now be at or below seal level .
  • the shore based facility may recover any additives which have been included with the basic drilling mud to form the enhanced mud/carrier fluid, and the additives and recovered drilling mud may be returned separately to the drilling rig, m separate tanks on the supply vessel, during a return trip.
  • the recovered additives and freshly processed mud may be stored on the rig.
  • the drilling mud recovered on the rig from the mud and solids from downhole using conventional solids separation equipment can be combined with fresh mud for pumping downhole, and when required the selected proportions of the additives can be added to fresh or recovered mud to form a carrier fluid for cuttings from downhole, and a slurry can be formed by combining the cuttings with the carrier fluid which is then stored on the rig for subsequent pumping to a supply vessel, to be returned to a shore based mud recovery and cuttings cleaning plant .
  • the tanks may be washed through and/or filters may be provided to prevent any such solids/cuttings from leaving the tank and being conveyed to the mud storage tank(s) on the rig.
  • the additional solids and liquid handling facilities on an offshore drilling platform therefore comprise a slurry mixing system for mixing a carrier fluid with the cuttings separated from the mud recovered from downhole, and a transfer pump for conveying the slurry to a storage tank on the rig or on a pontoon associated therewith.
  • drilling mud as the base for the carrier fluid means that an offshore drilling platform only requires the addition of one or more tanks for storing the slurry, and tanks for storing the additives to be mixed with drilling mud to form the carrier fluid.
  • the slurry storage tanks may need to include agitation means either of the tank or of the contents, or both, so as to ensure that the solids remain in suspension and do not settle out.
  • the same pipeline can be used for conveying the slurry to the slurry holding tanks as is used for conveying fresh mud from a supply vessel to the mud storage tanks on the rig or associated pontoon, and for conveying slurry from the slurry storage tanks on the rig or pontoon to the supply vessel, for return to shore.
  • the mud storage tanks on the supply vessel which are to be used for conveying the slurry from rig to shore may need to be modified so as to provide for frequent (eg regular or continual) agitation of the contents of the tanks.
  • the invention thus also lies in an offshore drilling rig having incorporated therein or in a pontoon alongside, additional storage tank facilities for storing at low level (at or below sea level) a slurry of drilling cuttings from downhole in suspension in a thixotropic carrier fluid, agitation means for agitating the slurry in the tank facilitates to prevent solids settlement, pipe means for conveying slurry from the storage facilities to a tank on a supply vessel and pump means for pumping slurry from the storage facilities through the pipe means .
  • the invention also lies in an improved offshore drilling rig as aforesaid which includes further tank means for storing additives to be mixed with drilling mud to form the carrier fluid, mixing means for mixing drilling mud and selected quantities of the additives to make up a carrier fluid, pump means for transferring carrier fluid to a mixing chamber to form a slurry with cuttings from downhole, and means for transporting the slurry to the said additional tank facilities on or associated with the rig.
  • the slurry is stored in bulk prior to transfer from the drilling site, in a tank containing agitation means.
  • transfer of slurry from the drilling site to a processing site may be effected by pumping along a pipeline.
  • the slurry is pumped and/or allowed to run by gravity from the storage tank into a tank on a road transporter, and after transportation the slurry is unloaded by pumping and/or by gravity into a suitable storage facility.
  • drilled cuttings may be removed from the carrier fluid using solids separation equipment similar to that used for separating cuttings from drilling mud at the drillhead, and following separation the solids are then processed typically for landfill, and the carrier fluid may be returned for re-use at the drillhead, or may be separated into a conventional drilling mud fraction and one or more additive fractions for return to the drillhead.
  • the fluid (s) may be transferred in the reverse direction from the processing site to the drillhead using the same pipeline and/or tanks on the road transporter or supply ship, typically tanks which are empty after delivery of slurry to the processing site.
  • the solids are easily, quickly and safely stored at the drilling rig.
  • the slurry is easily conveyed from a drilling rig to a supply boat, and onward from the supply boat to the point of processing, using pumps and hoses which are normally present in existing installations on the rig.
  • the transfer of slurries using these components, and the procedures for their use, are known and understood. 3. No additional hazards over those currently experienced in slurry transfer are created.
  • the method of transfer is not manpower intensive and the need to use r g and dockside cranes for long periods, is eliminated, as is the need for a crane at the final point of processing.
  • the method eliminates the need for multiple, possibly specialist containers, and extensive mechanical handling of these containers on the rig and at the process site. Thus where a rig mounted crane would be required for this purpose, it can be freed-up for transporting other commodities to and from the rig and supply vessel .
  • the method eliminates the requirement for inventory control, cleaning, repair, maintenance, certification and documentation of multiple containers .
  • the position of storage of slurry on the drilling rig can be flexible and is dependent only on the availability of suitable tanks, ie slurry could be stored m pontoon or tanks below deck. This flexibility has significant advantages for offshore drilling rigs where storage of large volumes of cuttings may be achieved while minimising the impact of the additional weight on variable deck load and rig stability. Where moderate volumes of slurry storage is required for limited periods only, temporary deck tanks may be employed quickly and easily.
  • the transfer rate of cuttings from the rig to the supply boat or road transport would normally be expected to exceed that achievable using containers .
  • the cost of the supply boat can be reduced if the loading cycle times at the rig and dock can be reduced.
  • the invention essentially uses the existing infrastructure of a typical offshore drilling rig with few modifications.
  • the invention is most effective when employed m a closed loop system in which compatible materials are employed for carrying the cuttings solids m suspension m the slurry
  • the invention is not restricted to closed loop arrangement and is equally applicable to open loop systems in which the carrier fluid may or may not be compatible with the drilling mud, and m wn ch there is no advantage or need, or little or no attempt is made to utilise the same tanks or pipelines for drilling muds, slurry, carrier fluids etc, and/or m wnich no attempt is made to return any recovered fluid from the remote cuttings cleaning and disposal facility.
