- CPF Central Processing Facility
- DCSG Direct Contact Steam Generation
- SAGD Steam Assisted Gravity Drain
- DCSGs are today considered unconventional boilers. They are preferably located at a hydrocarbon production site, such as a well, or pad, or at least close to a number of pads. A pad can be a collection of wells. At one of these locations, steam can be used directly or in a worst case scenario, the steam may have to travel a minimal distance.
- DCSGs can operate on dirty water and for the most part eliminate the "huge water treatment plant" requirement from the CPF. This new paradigm shift presents opportunities to re-think the CPF design and its function to optimize it for DCSG technology. At least 2 approaches to apply this new technology are possible.
- Embodiments of the present disclosure include methods, apparatus, and systems to optimize the CPF for DCSG applications.
- a steam outlet conduit associated with the DCGSs can be less than one mile in length.
- the steam outlet conduit associated with the DCGs can be at the hydrocarbon production site (e.g., well), effectively placing the steam outlet conduit zero feet away from the oil production site.
- the steam outlet associated with the DCGS can be up to two miles away from the oil production site.
- the DCSG system can be configured to produce as small as 1,000 bpd of steam and can serve a single well.
- the DCSG system can be configured to produce as large as 50,000 bpd, if the system serves a number of closely positioned pads that require high volumes of steam.
- the CPF can now be located any reasonable pipe line distance away from the wells and pads.
- the CPF can be located remotely from the hydrocarbon production site and/or the DCSG.
- the CPF can be located a distance from the oil production site in a range from 10 miles to 100 miles, although embodiments are not so limited and the CPF can be located closer than 10 miles or further than 100 miles from the oil production site.
- the CPF could service over 100,000 bpd of unconventional oil which would equate to a conventional CPF that previously would have had to produce over 300,000 bpd of steam.
- This disclosed large CPF could be contained at one location and be third party operated by a service provider who sells the CPF services to a producer or a number of producers. This configuration would again reduce the Opex of the unconventional oil recovery process.
- Fig. 1 depicts a SAGD CPF, in accordance with embodiments of the present disclosure.
- the steam boiler 1 is typically an OTSG, but could also be a drum boiler or other conventional boiler design .
- a DCSG could also be used at the CPF in place of an OTSG at the drawn location but it could compromise the efficiency of the complete system due to steam transportation losses to the pads if located in the CPF.
- Steam traveling through a steam conduit 2, which is fluidly coupled with the steam boiler 1, is produced by the steam boiler 1.
- the steam that is transported to the pads via the steam conduit 2 is to be injected into the SAGD wells. In some cases, the wells could be over five miles away from the steam generator. Significant system energy losses, sometimes over 10%, can be suffered due to shipping the steam these long distances.
- a natural gas feed conduit 3 is fluidly coupled to the steam boiler 1 and can carry natural gas or natural gas plus a produced gas fuel supply to the steam boiler 1.
- a waste water conduit 5 contains the blow down waste water required to maintain the health of the conventional boiler.
- a boiler feedwater (BFW) conduit 4 contains the boiler feedwater provided to the steam boiler 1 and is fluidly coupled to the steam boiler 1.
- the boiler feedwater is buffered in a storage tank 8, which is supplemented in its supply of clean and treated boiler feedwater from clean and treated makeup feedwater provided to the storage tank 8 via the makeup feedwater conduit 7.
- the feedwater is manufactured from returned produced water, which is provided from a bitumen treating and separation plant 16 to a water treatment plant 9 via a produced water conduit 19.
- the returned produced water is water returned from the bitumen well .
- the dirty produced water provided to the water treatment plant 9 via the produced water conduit 19 goes through an extensive clean up and filtering process in the water treatment plant 9 that makes up the majority of the CPF.
- the water treatment plant 9 is diagrammatically shown in Fig. 1.
- the water treatment plant can produce waste water, lime sludge and cake, which are depicted as exiting the water treatment plant 9 via waste conduit 10.
- the feedwater provided to the boiler 1 can be treated and supplied to the boiler at a location in close proximity to a location of the hydrocarbon production site.
- Bitumen emulsion and produced gas arrive from the pad via production conduit 15.
- the mix is processed and separated via separation system 16, which can be made up of components such as one or more of a Free Water Knockout systems, skimmer (e.g ., skim tank), and gas separation systems.
- the produced gas can be provided to a treatment system 18 via a produced gas conduit 17.
- the treatment system 18 can clean up the produced gas, which can be re-used in the boilers (e.g ., steam boiler 1) and pads.
- semi-processed produced water can be shipped to the water treatment process or "plant" as shown as water treatment plant 9.
- Some diluent from diluent storage tank 20 may be injected into the bitumen separation system 16 through a first diluent conduit 21.
- the reduced viscosity bitumen is transported through bitumen conduit 22, which may need additional amounts of diluent added to become Dilbit or salable product, as shown in hydrocarbon storage and handling tank 24.
- the Dilbit or salable product can be transferred through hydrocarbon conduit 23 into the hydrocarbon storage and handling tank 24.
- the Dilbit or salable product can be pumped from the hydrocarbon storage and handling tank 24 via a pump 25 and finally exit via exit conduit 26 to a sales pipeline, in an example.
- Electrical power is shown as power 6, which would be used to power the CPF and the pads.
- the source of the power 6 can be from an on-site generator and/or electrical transmission line connected to a power plant.
- a carbon-based fuel and blanket and lift gas can be received from the CPF via a gas conduit 13.
- conduit 11 is used to provide a method to premix preferred amounts of well head gas into natural gas supply 12, which can be in
- conduit 14 can contain a non-natural gas, mixed but treated well head gas, to potentially be used as a blanket gas or other hydrocarbon recovery tool .
- Basic subsystems such as glycol loops and condensate systems have not been shown to aid in clarity.
- Fig. 2A is an example of a new CPF optimized for a DCSG well, pad or series of pads configuration, in accordance with embodiments of the present disclosure. Similar elements, such as those depicted and discussed with respect to Fig. 1 are denoted with a "prime" symbol in Fig. 2A.
- the produced gas treating facility 18, as depicted in Fig. 1 can include the same or similar features with respect to the produced gas treating facility 18', as depicted in Fig. 2A.
- Fig. 2A depicts an embodiment that includes a minimal water treatment system 27. In some cases, the minimal water treatment system can include just a coarse filter.
- the source of DCSG boiler feedwater provided to the minimal water treatment system 27 via the produced water conduit 19' could come directly from the Free water Knockout or from an additional downstream skim tank, which can be included in the separation system 16'. Neither of these devices are shown in Fig. 2A for simplicity.
- the lightly (e.g . minimally) treated water then travels through treated water conduit 30 into a dirty feedwater storage tank 28 and is transported through a boiler feedwater conduit 29 to the well, pad, or pads to be consumed by the DCSG.
- the well, pad, and/or pads can be referred to as a hydrocarbon production site.
- the make-up feedwater in conduit 7' could be fresh, dirty or contaminated water, or pond water from a bitumen mining operation .
- Fig. 2B depicts an example of a new well, pad, or series of pads optimized for a DCSG configuration that compliments the CPF in Fig . 2A, in accordance with embodiments of the present disclosure.

- the steam outlet associated with the DCGS can be up to two miles away from the oil production site.
- Generated steam conduit 32 transfers steam generated by the DCSG system 31 to three closely positioned pads (pads not shown), although embodiments are not so limited .
- the generated steam conduit 32 could be sized to only service one well or many wells or a single pad or many pads.
- the key to keeping a high efficiency and minimizing both Capex and Opex would be to minimize the steam losses by minimizing the distance the steam is required to travel through careful DCSG system 31 placement versus deploying the minimum amount of DCSG systems required to complete the desired unconventional oil recovery.
- a waste conduit 33 could be used to eject the waste solids from the produced water if superheat were used in the DCSG system 31 or blowdown waste conduit 34 could be used to eject blowdown if saturated steam conditions were generated in the DCSG system 31.
