    Abstract: A method of patterning a substrate includes providing a first photoresist on a substrate, layering a second photoresist on the first photoresist, exposing the second photoresist to a first pattern of actinic radiation, and developing the second photoresist such that portions of the second photoresist are dissolved providing gaps between features of the second photoresist, wherein the gaps uncover portions of the first photoresist. Then, the method includes exposing the first photoresist to a second pattern of actinic radiation and developing the first photoresist such that portions of the uncovered portions of the first photoresist are dissolved providing gaps between the features of the first photoresist where a portion of the substrate is exposed.

    Abstract: Apparatus and methods provide for a tubing head spool (200) that may be disposed in a wellhead (100) during drilling or other wellbore operations, after which a tubing hanger adapter (206) may be disposed within the tubing head spool (200) for hanging tubing. Methods include installing a tubing head spool (200) onto a wellhead, installing a blow out preventer onto the tubing head spool, drilling a well by running downhole tools and at least one casing string through the tubing head spool, running a tubing hanger adapter bushing (202) through the blow out preventer and into the tubing head spool, running a tubing string into the well, and landing out the tubing string using a tubing hanger configured to hang within the tubing hanger adapter bushing.

    Abstract: A method of microfabrication includes forming a first relief pattern on a target layer of a substrate, coating the first relief pattern with a first solubility-shifting agent, layering a first polymeric fill on the first relief pattern, and diffusing the first solubility- shifting agent into the first polymeric fill to provide a solubility-shifted region of the first polymeric fill. Then the method includes forming a second relief pattern over the first relief pattern, coating the second relief pattern with a second solubility- shifting agent, layering a second polymeric fill on the second relief pattern, and diffusing the second solubility- shifting into the second polymeric fill to provide a solubility- shifted region of the second polymeric fill. Finally, the solubility-shifted regions of the first polymeric fill and the second polymeric fill are developed and the target layer is etched.

    Abstract: A method of determining an API gravity of a crude oil is provided. The method includes obtaining a reservoir sample containing the crude oil and heating the sample to a first temperature using an oxidative testing apparatus. The sample is then heated to a second temperature, which is greater than the first temperature, over a period using a fixed heating rate. The rate of carbon dioxide emission from the sample is detected during the period of heating to the second temperature. The peak rate of carbon dioxide emission from the sample is then determined and the peak carbon dioxide emission temperature associated with the peak rate of carbon dioxide emission is also determined. The API gravity of the crude oil in the reservoir sample is determined using an empirical correlation between API gravity and the peak carbon dioxide emission temperature associated with the fixed heating rate.

    Abstract: Methods of evaluating a surfactant (100) may include ultrasonicating a mixture of oil, water, and the surfactant to form at least one of the following: a sub-macroemulsion, a macroemulsion phase or a combination of the aforementioned (101); separating the sub-macroemulsion from the macroemulsion phase (102); introducing the sub-macroemulsion into a foam container (103); performing a first automated phase identification of the sub-macroemulsion (104); introducing a gas into the sub-macroemulsion to generate a column of foam, where the column of foam has a height in the foam container (105); performing a second automated phase identification of the sub-macroemulsion (106); and measuring the height of the column of foam in the foam container (107). In these methods, the first and second automated phase identifications may be configured to quantify one or more liquid phases and a foam phase in the column.

    Abstract: A method for recovering hydrocarbons from a hydrocarbon-containing formation. The method may include determining the hydrocarbon-containing formation pressure, temperature, and other properties such as the total acid number and total base number of the hydrocarbons, rock type, and brine ionic composition. The method may also include determining a desired amount of wettability alteration of the formation and modeling the formation. Modeling the formation may be based on the determined pressure, temperature, total acid number and total base number of the hydrocarbons, rock type, and brine ionic composition. The method may also include preparing an aqueous wellbore fluid based on the estimated wellbore fluid composition and injecting the aqueous wellbore fluid into the hydrocarbon-containing formation.

    Abstract: Acidizing treatments for carbonate reservoir may include a surfactant comprising one or more of C8-C30-alkyloxyglycoside-subsliluled hydroxysultaine, C8-C30-alkylamidopropyl hydroxysulfobetaine, poly(diallyldimethylammonium chloride), C8-C30-alkyl amido alkylamine oxide, C8-C30-alkyl-amido amine oxide, C8-C30-alkyl amine oxide, C8-C30-alkylaryl amine oxide, C8-C30-alkyl polyether phosphate, C8-C30-alkyl polyether phosphonate, C8-C30-alkyl ether phosphonate, C8-C30-alkyl amido ammonium propyl sulfonate, C8-C30-alkyl amido ammonium vinyl sulfonate, C8-C30-alkyl ether sulfonate, C8-C30-alkyl amido ammonium propyl sulfonate, C8-C30-alkyl ether sulfonate, alpha olefin sulfonate, C8-C30-alkyl benzene sulfonate, C8-C30-alkyl ethoxy carboxylate, C8-C30-alkylphenol ethoxylate carboxylate, and C8-C30-alkyl amido ammonium carboxylate. These acidizing treatments may also include an aqueous acid solution or mixture. In these acidizing treatments, the surfactant may be configured to partially or fully adsorb on a carbonate formation to retard the partial dissolution of the formation. Corresponding methods of reducing the reactivity of acidizing treatment may include introducing these acidizing treatments into wellbores such that the acidizing treatments contact carbonate formations.
