    Abstract: The rate of evaporation in an evaporation pond containing contaminated produced or process water from a hydrocarbon production operation is increased by pumping water from just beneath the surface of the pond through a pipe extending around the periphery of the pond. The water is dispensed around the periphery of the pond from ports in the pipe and then trickles down into the pond water. The pond has a black plastic lining, with a border region that is not submerged. The water from the pipe trickles down across the un-submerged black lining that is at an elevated temperature due to radiative solar heating, and energy is thereby imparted to the water to increase the rate of evaporation.

    Abstract: A method for producing heavy oil, the method including producing oil by SAGD or a SAGD variant in an array of wellpairs until an SOR increases, then shutting in every other injector and injecting steam plus noncondensable gas (NCG) in the remaining injectors and producing oil from all producers. The method reduced steam usage by at least 40% or even at least 50% in the later stages of the well, without comprising oil production.

    Abstract: Example embodiments of the present disclosure provide a new process (tool) to predict the production effects from MBEs. This tool can be based on an extensive study which risked the likelihood of MBE occurrence for patterns grouped by sand and completion type. In one aspect, a method includes determining a risk of Matrix Bypass Event (MBE) occurrence for a given sand type; assigning an MBE status to the given sand type based on the risk of MBE occurrence; and predicting an effect of the MBE status for the given sand type on production in a target production well.

    Abstract: A method for producing heavy oil using solvent injection without gas interference at the electric submersible pump (ESP), the method including completing the injection well with two or more injector tubings, at a heel and toe, and optionally therebetween. Ideally, when gas locking of the ESP is detected, the operator switches to toe dominant injections, mitigating the gas locking problem, and producing oil at a faster rate than possible with evenly distributed injections.

    Abstract: Pressure sensing plugs are used to check pressure in various void or cavities of a wellhead or Xmas tree of an active hydrocarbon well. Pressure sensing plugs (51) are provided at various points in the wellhead or Xmas tree (50). Each plug incudes a pressure transducer (39) and associated electronics allowing the pressure to be read by a hand held reader device. Alternatively, the plugs may include a radio transmitter for transmitting sensed data to a monitoring system via a wifi network or similar to a central control room on a hydrocarbon producing platform. In this way, the pressure at the various points in the wellhead/Xmas tree may be checked without exposing the cavity or void.

    Abstract: The invention relates to the dissolution of amorphous dithiazine (a-DTZ) or polythioformaldehyde or other polymeric by-products of the treatment of hydrocarbon products (a-DZT) to remove them from surfaces. These are solids that build up on surfaces of processing plant and are resistant to most chemical treatment. The treatment requires treating the surface with an effective amount of a mercaptan or an amine. Surfactants to keep the dissolved a-DTZ or other components from redepositing elsewhere are also described, as is the use of hydrogen sulfide to add in removal by mercaptans.

    Abstract: The invention relates to a cementing tool (1) and method for setting a cement plug. Instead of the conventional “balanced plug”, the technique involves pumping cement whilst pulling and rotating the tool. The cementing tool (1) includes nozzles (9) for jetting cement which are located in a relatively narrow region (8) of the tool and a larger diameter choke region (5) proximal of the nozzles (9). The end of the tool (11) is closed off and tapered. The tool is passed down the well to a location where it is desired to set a plug, then cement is injected whilst rotating and withdrawing the tool. The jets of cement help displace existing fluid in the well thereby reducing mixing of the existing fluid with the cement, The choke region (5) increases the flow energy, whilst the tapered end (11) helps prevent disruption to the cement as the tool is withdrawn. The choke region (5) may be expandable to allow the tool to pass through a cased part of the well and then set a plug in an under-reamed open hole part of the well.
