Abstract: Methods for using shut-in pressures to determine uncertainties in a hydraulic fracturing process in a shale reservoir are described. Data commonly collected during multistage fracturing is used to calculate propped fracture height and induced stresses, as well as other variables, in the presence of horizontal stress anisotropy. These variables can then be incorporated into reservoir simulations to improve the fracturing monitoring, forecast hydrocarbon recoveries, or modify fracturing plans.

Abstract: The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g., in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.

Abstract: Methods and systems relate to generating steam from water that contains dissolved organic compounds. The methods mix a polymerization inhibitor with the water prior to feeding the water into a steam generator. The polymerization inhibitor limits coupling of the dissolved organics under boiler conditions to mitigate fouling issues within the boiler.

Abstract: The invention relates to a method and apparatus for treatment of produced or process water from hydrocarbon production to reduce the volume of the produced or process water while simultaneously reducing the salinity of a highly saline stream, for example, the brine from a seawater desalination plant. The method includes causing a feed stream comprising produced or process water to flow through the lumen of a hollow fiber osmotic membrane 4 which is immersed in an open channel 2 or tank of flowing draw solution 6 which has high salinity. In this way, water from the feed stream is drawn through the osmotic membrane 4 by an osmotic pressure differential caused by the difference in salinity between the feed stream and the draw solution 6.

Abstract: A process of liquefying a natural gas stream in a liquefied natural gas facility is provided. The process includes cooling the natural gas stream in a first refrigeration cycle to produce a cooled natural gas stream. The process also includes cooling the cooled natural gas stream in a first chiller of a second refrigeration cycle, the cooled natural gas stream exiting the first chiller at a first pressure. The process further includes cooling the cooled natural gas stream in a first core of a second chiller of the second refrigeration cycle. The process yet further includes cooling a refrigerant of a refrigerant recycle stream separate from the cooled natural gas stream in a second core of the second chiller of the second refrigeration cycle, wherein the refrigerant recycle stream enters the second chiller at a second pressure that is lower than the first pressure of the cooled natural gas stream.

Abstract: This disclosure describes a method of calculating fluid distribution from a hydraulically fractured well, especially during a plug-and-perf hydraulic fracturing operation. The Distributed Acoustic Sensing (DAS) data is used to quantify the fluid distribution in separate perf clusters during fracturing, and the result can be used for completion design and optimization, hydraulic fracturing, and ultimately for oil and gas production.
