Abstract: Compositions may include a wax modifier that is the product of a reaction between a polysaccharide having a number of sugar subunits in the range of 2 to 60 and one or more fatty acid reagents, and a reservoir fluid produced from a subterranean formation comprising one or more components capable of producing waxes. Methods may include contacting a hydrocarbon fluid with a wax modifier, wherein the wax modifier is the product of the reaction of a polysaccharide and one or more fatty acid reagents. Methods may also include introducing a wax modifier into a wellbore penetrating a subterranean formation, wherein the wax modifier is the product of a reaction between a polysaccharide and one or more fatty acid reagents; producing hydrocarbons from the subterranean formation; and allowing the wax modifier to inhibit the precipitation of a wax.

Abstract: This disclosure is drawn systems, devices, apparatus, and/or methods related to the separation of a mixture of solids according to size and the separation of solids from liquid. Specifically, this disclosure is drawn to an adjustable weight set for use on vibratory separators. In some examples, the adjustable weight set may include a base plate rotatable about an axis and extending radially outward from the axis; a plurality of slots extending through the base plate and being disposed between a radially outward periphery of the base plate and the axis; a plurality of weights coupled to each other about the base plate; and a weight locking tab that partially surrounds the base plate that may include one or more hooks extending through a portion of a slot.

Abstract: Embodiments relate to fluid flow improvers containing a copolymer with a siloxane group incorporated thereto. The fluid flow improvers may include polymer/copolymer having the characteristic of inhibiting wax/paraffin crystalline growth, modifying wax/paraffin crystal growth, dispersing of wax/paraffin, preventing the deposition of wax/paraffin, aiding the removal of wax/paraffin or depressing of the pour point of a wax/paraffin-containing fluid. The fluid flow improvers described may be employed alone, or may be used in combination with one or more additives for improving the low temperature flowability and/or other properties and may also be employed in combination with one or more organic solvents and/or aqueous solvents.

Abstract: A method of cleaning a wellbore prior to the production of oil or gas is disclosed, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake. The method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid includes an aqueous fluid, and imino diacetic acid or salt thereof. Optionally an acid buffering agent, and a weighting age are also included. The breaker fluid is formulated such that after a predetermined period of time and the filter cake present in the wellbore or on the wellbore face is substantially degraded. Other methods may also include drilling the wellbore with a water-based drilling mud that forms a water-based filter cake, wherein the method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid may include an aqueous fluid, and an iminodiacetic acid or a salt thereof.

Abstract: A method of electrically logging a section of a wellbore includes circulating an oil-based wellbore fluid within the wellbore and allowing filtration of the oil-based wellbore fluid to form a conductive filtercake on a wall of the wellbore; placing within the wellbore a wellbore logging tool with at least one pad capable of applying a current to a portion of the conductive filtercake and wellbore wall; applying electrical current from the at least one pad; and collecting an electrical log of the portion of the wellbore that has had electrical current applied thereto.
