    Abstract: Single well SAGD is improved by having one or more injection segments and two or more production segments between the toe end and the heel end of a flat, horizontal well. The additional injection points improve the rate of steam chamber development as well as the rate of production, as shown by simulations of a central injection segment bracketed by a pair of production segments (-P-I-P-), and by a pair of injection segments with three production segments (-P-I-P-I-P). Although the completion of the single well costs more, this configuration allows the development of thin plays that cannot be economically developed with traditional SAGD wellpairs.

    Abstract: The invention relates to an improved method for installing a dual/multiple lateral well where the overburden casing is relatively narrow. A tapered liner is employed for the first lateral. The liner has a narrow production section (109) and a larger diameter section (104) allowing a liner (116) for Lateral B to be run through it, after a window (114) has been milled. The system saves a drilling run and a liner installation run, as well as avoiding the need to set a liner hanger in Lateral A.

    Abstract: The invention relates to a system, method and apparatus for removing heavies from natural gas. Natural gas and an external rich reflux gas feed are processed in a single column refluxed absorber. A bottoms stream is routed to a first heat exchanger and then to a stabilizer column where an overhead stream from the stabilizer column is routed through a condenser for partial separation into an overhead stream. A rich solvent may be introduced to the stabilizer column. The overhead stream is routed through a condenser for partial separation into a stabilizer reflux and a second overhead stream lights. The second overhead stream lights is routed to a heat exchanger and then routed to a partial condenser where the stream is separated into a heavies rich reflux stream, a distillate stream and heavies treated natural gas stream. The rich reflux is routed through a heat exchanger and the rich reflux is pumped to the single column refluxed absorber to be introduced into the single column refluxed absorber as the external rich reflux gas feed.

    Abstract: Systems and methods of forming a seal employ a robust metal sealing unit for tubulars used in rotary drilling. Specifically, eutectic alloy is used to seal a tubular to a wellbore after drilling. A downhole heater melts the alloy, allowing the alloy to expand and drain before it cools and solidifies between the wellbore and tubular, forming a gas tight seal.

    Abstract: A plug for Plug and Abandonment (P&A) operations. The plug is a two-part plug of bismuth-based alloy and resin, allowing for sealing of an oil well using two different mechanisms with a shorter plug. The sealing can be rock-to-rock and/or cast-in-place.

    Abstract: A uniform oleophobic or oleo- and hydrophobic film is applied to equipment used in the petroleum industry. The methods can be applied to new equipment or equipment pulled from service, with the application process being performed in a controlled environment or the field. Applicator tools for efficient delivery and application of cleaners, solvents, and films used in the coating process are also described.

    Abstract: Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.

    Abstract: The invention relates to the drilling of subsurface oil and gas wells and the installation of subsurface equipment (11). A lifting vessel 7 brings heavy equipment such as Xmas trees or manifolds and wet parks this equipment (11) on the seafloor (5) during good weather when the significant wave height is low. The equipment (11), once it is underwater, has much lower weight and may easily be moved into place onto a wellhead (10) at an appropriate time using lower capacity lifting gear. The timing of this operation is much less sensitive to weather conditions because the equipment does not need to pass through the splash zone (sea surface). This makes for efficient use of expensive drilling rig time, and allows for acceleration of production of first wells on the template as critical heavy lifts could not else be done until rig has left the location. (FIG. 1).
