Title: Base oil composition for use in oil-base drilling mud compositions, and methods of producing same
Inventor: SCALLEY MATTHEW
IPC: E21B21/06
Filed: 2018-05-16
Abstract: A process for producing a base oil composition particularly adapted for use in oil-base drilling mud compositions. The process includes contacting drilling waste containing an oil-base mud phase with a solvent to produce a mixture of liquids and solids, separating the two phases, partially evaporating the liquids phase to produce an oil base composition substantially lacking low molecular weight carbon chain compounds and also lacking significant concentrations of benzene, toluene, xylene, and/or ethyl benzene, and having increased closed-cup flashpoint when compared to the oil-base mud phase in the drilling waste. The resulting base oil has enhanced health and safety characteristics for workers interacting with and otherwise exposed to the oil base composition during transporting, conditioning or using such compositions. The base oil produced and drilling methods using the recovered and recycled mud are also described.

Title: Facilitating location-based sales venue transaction payments using non-location-based identity targets
Inventor: ROGERS GARETT
IPC: G06Q20/38
Filed: 2019-04-08
Abstract: A method of processing payments in a location-based sales venue such as a restaurant.  Each customer location has a physical identity target attached in proximity thereto comprising a unique system-wide identifier readable by mobile customer devices.Targets might be visually readable, using QR codes or the like, or might be a short range radio beacon broadcasting the identifier (NFC, RFID etc.) -- they do not contain human-readable location indication information. The identifiers associated with the targets do not contain location- or venue-specific information, and are recorded in relation to location records corresponding to individual customer locations in the venue in a location database held on a server. On reading of a target by a customer device and a related location transmission to the server, the server can associate the transmission with its related customer location in the venue-associated POS system, facilitate a payment transaction for the amount owing at the selected customer location through a transaction gateway, and provide a transaction completion indication to the POS system.  The method allows for enhanced velocity in deployment and Maintenace of location targets, and enables mobile device-based payment in venues previously not offering same.  Systems and software are also disclosed.
