    Abstract: Process for converting synthesis gas to hydrocarbons which comprises contacting a gaseous stream comprising synthesis gas, at an elevated temperature and pressure, with a suspension comprising a particulate Fischer-Tropsch catalyst having a particle size in the range 5 microns to 500 microns, suspended in a liquid medium, in a system comprising at least one high shear mixing zone and a reactor vessel. The suspension and the gaseous stream is passed through the high shear mixing zone(s) wherein the gaseous stream is broken down into gas bubbles. The suspension having gas bubbles dispersed therein is discharged from the high shear mixing zone(s) into the reactor vessel, and suspension comprising the particulate Fischer-Tropsch catalyst suspended in the liquid medium and liquid hydrocarbon products is withdrawn from the reactor vessel and at least a portion of the suspension is recycled to the high shear mixing zone(s) via an external conduit at a flow rate of at least 10,000 m3 of suspension per hour.

    Abstract: The problem of lost circulation is pertinent to the oil industry. To prevent fluid loss, a lost circulation material (LCM), or more generally, a plugging material, can be used to effectively plug the fractures in the rock formation. If the fractures are in the production zone, it is also ideal to unplug them when the drilling operation is complete. Therefore, a material engineered to degrade after a desired period would be useful. In examples, a plugging material has been developed by gelling an oil-based fluid using a low molecular weight gelator, dibenzylidene sorbitol (DBS). DBS gels are robust and show plugging behavior. DBS is shown to chemically degrade in presence of an acid. Hence, a self-degrading gel can be synthesized by incorporating an acid into the system. Further, by varying the type and concentration of the acid, the degradation time of the gel can be controlled.
