Abstract: A method includes performing a drilling operation using a drilling fluid; determining pressure losses of the drilling fluid in the drilling operation; updating non-linear regression coefficients to model the drilling operation; and performing gel strength tests on the drilling fluid. The method also includes determining optimal drilling parameters and the non-linear regression coefficients and determining optimal hole cleaning energy by balancing a mechanical energy level of the drilling fluid based on a maximum pump pressure of the mud pump and the optimal drilling parameters. The maximum pump pressure is determined based on the pressure losses and a range. The method further includes determining pressure changes created by the drilling operation using the optimal hole cleaning energy and results of the gel strength tests; determining an estimated equivalent circulating density based on the pressure changes; and modifying or maintaining the drilling operation based on the estimated equivalent circulating density.

Abstract: Embodiments of systems and methods for generating power in the vicinity of a drilling rig are disclosed. During a drilling operation, heat generated by drilling fluid flowing from a borehole, exhaust from an engine, and/or fluid from an engine's water (or other fluid) jacket, for example, may be utilized by corresponding heat exchangers to facilitate heat transfer to a working fluid. The heated working fluid may cause an ORC unit to generate electrical power.

Abstract: A craneless elevatable MGS vessel and U-tube assembly can be delivered on a winch truck to a drilling site and assembled in a far shorter time and without the need of having a crane and crane operator attend to the movement and placement of the MGS vessel and attached U-tube mud lines to a mud handling system in a drilling rig. The MGS vessel of the present application can be a standard type of MGS vessel well known in the industry. By fabricating this MGS vessel with attached and moveable U-tube connectors for the mud line, the system can be moved and assembled at the drill site without crane intervention. Moreover, the ability to raise the MGS vessel, after placement in its vertical position, permits ready attachment to multiple diverse drilling rig configurations.

Abstract: One system embodiment includes: an inlet sensor that measures a fluid quality of an input fluid stream; an arrangement of separation units operating to extract contaminants from the fluid stream; and a user interface (UI). Each separation unit produces a respective output fluid stream, exhibiting a performance that is impacted by a respective operating parameter, and has an outlet sensor that measures an output fluid stream quality. The UI receives fluid quality measurements from the inlet and the outlet sensors, responsively derives a performance value for each separation unit and an overall performance value for the arrangement, and displays each of the performance values. The UI may further set the operating parameter values to automate and optimize the operation of the arrangement for different drilling conditions. The fluid quality measurements may indicate contaminant concentrations, and the performance values may account for separation efficiency, energy consumption, reliability, and next service date.

Abstract: Systems and methods for extracting minerals from an underground mineralization zone located below the surface at an oil and gas drilling site. The system includes a vertical drilling means for drilling a vertical bore extending from the surface at the oil and gas drilling site into the mineralization zone, a second horizontal drilling means for drilling at least one horizontal production bore into the mineralization zone. The first horizontal drilling means and the second horizontal drilling means are configured to return material from the mineralization zone to the surface where the mineral content of the material is analyzed and a separator separates minerals, waste and drilling mud from the material. The method includes steps of drilling a horizontal assessment bore, analyzing assessment material for a desired mineral, drilling a horizontal production bore, producing production material containing the desired mineral, and separating the desired material from waste and drilling mud.

Abstract: Methods for selectively replacing the larger particles screened from a drilling fluid may include: circulating a drilling fluid comprising a base fluid and a plurality of particles through a wellbore penetrating a subterranean formation; passing the drilling fluid over a screen having a mesh size, thereby separating the plurality of particles into screened particles having a diameter greater than or equal to the mesh size and retained particles having a diameter smaller than the mesh size; adding a concentration of replenishment particles to the drilling fluid that comprises the base fluid and the retained particles, wherein a PSD of the replenishment particles has a d25REP greater than or equal to the mesh size; and re-circulating the drilling fluid including the replenishment particles back into the wellbore.
