Methods and systems for predicting interfacial tension of reservoir fluids using downhole fluid measurements
10 Jan 23
Methods and systems are provided for characterizing interfacial tension (IFT) of reservoir fluids, which involves obtaining fluid property data that represents fluid properties of a reservoir fluid sample measured downhole at reservoir conditions, and inputting the fluid property data to a computational model that determines a value of oil-water IFT of the reservoir fluid sample based on the fluid property data.

Rig operations controller
3 Jan 23
A method can include, during drilling operations at a wellsite, receiving operational data, where the data include hookload data, surface rotation data and block position data; training a controller using the hookload data, the surface rotation data and the block position data for determination of one or more transition thresholds, where the transitions thresholds include an in-slips to out-of-slips transition threshold and an out-of-slips to in-slips transition threshold; during the drilling operations, receiving additional operational data that include additional hookload data; and storing at least a portion of the additional operational data in association with slips state as determined based at least in part on a comparison of at least a portion of the additional hookload data and at least one of the determined transition thresholds.

Utility
Method of creating and executing a plan
3 Jan 23
A method includes accessing a domain model plan that includes a time independent initial state and a time independent goal state and sequences of events that include a sequence of a first event, a second event and a third event with conditional interrelationships; accessing operational data that include a failure condition for the third event and a time constraint for the failure condition; issuing a control instruction to rigsite equipment to perform a drilling-related action for generating the third event; during performance of the drilling-related action for generating the third event, receiving sensor data germane to the failure condition; upon occurrence of the failure condition, timing a duration of the occurrence of the failure condition; comparing the duration to the time constraint for the failure condition; and, based on the comparing, deciding to re-plan the domain model plan or to continue execution of the domain model plan.

Utility
Methods for wellbore strengthening
27 Dec 22
A wellbore fluid may include an oleaginous fluid forming a continuous phase; a non-oleaginous fluid forming a discontinuous phase; at least one emulsifier stabilizing an emulsion of the non-oleaginous continuous phase within the oleaginous continuous phase; and at least one viscosifier dispersed into the oleaginous continuous phase in a concentration of at least 4 ppb; wherein upon subjecting the wellbore fluid to shear rate of at least 10,000 s−1, the emulsion is disrupted and the non-oleaginous fluid contacts the at least one viscosifier, thereby solidifying the wellbore fluid.
