Abstract: A technique facilitates production of desired well fluids from a lateral wellbore or wellbores. Aspects of the technique comprise drilling and completing the main wellbore which may include a lower lateral wellbore portion. A production deflector may be run downhole into the main wellbore, and then a lateral wellbore section, e.g. an upper lateral wellbore section, may be drilled from the main wellbore. A liner may then be run downhole and out into the lateral wellbore section. The liner comprises a scab portion which ends up disposed across the main wellbore. Subsequently, the scab portion is removed, e.g. milled, to enable communication with both the lateral wellbore section and the main wellbore extending below the lateral wellbore section.

Related grout slurries formed from the grout composition, grouts, and methods of grouting a wellbore are also disclosed.

Abstract: Lithium recovery processes are described using concentration and conversion techniques. A vaporizer or membrane can be used to concentrate lithium and precipitate impurities. A conversion process can be used to replace anions in lithium bearing streams by adding a second anion and precipitating lithium in a salt with the second anion. Rotary separation can be used to separate the precipitated lithium salt.

Physical (e.g., density) and chemical (e.g., total dissolved solids and hardness) properties of the material can be also quantified using ML techniques.

Abstract: Methods and systems for conveying a WFT via drill pipe within a wellbore penetrating a subterranean formation and setting two packers of the WFT on opposite sides of a zone of interest of the formation, thereby isolating an interval of an annulus between the WFT and a wall of the wellbore. DTT of the formation is then performed by operating two WFT pumps of the WFT to pump fluid from the formation via the isolated interval, through the WFT, and out of the WFT to the wellbore, while operating mud pumps to pump drilling mud into the wellbore and thereby convey a mixture of the drilling mud and the pumped formation fluid through the annulus to a mud gas separator. Gas from the mud gas separator is used to measure a surface production rate of the formation fluid.

Abstract: A technique facilitates a drilling operation, e.g. a land-based drilling operation, by enabling a substantial reduction in the number of equipment components. According to an embodiment, a mud pump assembly is provided with at least one mud pump located on a rig positioned at a wellsite. The mud pumps may be run to perform a mud pumping operation by pumping mud downhole during drilling of a borehole, e.g. a wellbore. During stoppage of the mud pumping operation, the same mud pumps are utilized to perform a cementing operation in which cementing fluid is pumped downhole for cementing of casing. The use of the same mud pumps enables the operator to eliminate not only the separate cement pumps otherwise used for the cementing operation but also the motive units that would be associated with those separate cement pumps.
