Abstract: Methods and systems are provided for induc ing seismic energy waves in a subterranean formation. More particularly, improved seismic transducers are provided that comprise enhanced baseplates. Baseplates are provided that comprise an intermediate plate and a plurality of contact plates secured to the underside of the intermediate plate. The contact plates provide a surface area for engagement with the ground surface that is more limited than the lower surface area of the intermediate plate. Advantages of such baseplate enhancements include, but are not limited to, a reduction of baseplate harmonics or ringing and enhanced baseplate strength so as to reduce baseplate fatigue or failure, a reduction of baseplate flexure. These advantages ultimately translate to improved seismic surveys, having higher resolution of the formations surveyed and resulting in surveys reaching greater depths.

Abstract: A method for reducing thermal loss in a formation comprising two zone capable of production. The method first begins drilling a pair of wells, comprising a first well and a second well in a formation having two production zones, wherein one production zone is a thief zone such that the first well and the second well are in fluid communication with the thief zone. A sealing agent is injected into the thief zone via a first well and produced from the second well. Either the first well or the second well is then capped to form a capped well and a uncapped well. An amount of activating agent is injected into the uncapped well to form in-situ a thermally restrictive substance inside the thief zone.

Abstract: Target chemicals are monitored at very low concentrations in pipelines or vessels such as storage tanks using surface enhanced Raman spectroscopy analysis of a sample. A liquid sample having a target chemical such as biocides, corrosion inhibitors, scale inhibitors, anti-foaming agents, emulsion breakers, and hydrate inhibitors are tested while exposed to a prepared and charged surface of a coupon so as to draw the target material to the prepared and charged surface. The charged surface is fairly precisely charged using two other electrodes to calibrate the charge on the surface of the coupon. With the target substance presumably drawn to the coupon, the molecules on the surface of the coupon are excited by monochromatic light such as from a laser to induce vibrations within the molecules.

Abstract: This invention relates to a downhole hydraulic pump for hydrocarbon wells that is installed and operated using coiled tubing. The downhole hydraulic pump is driven by a hydraulic power system positioned at the surface and connected through a closed loop system using multiple channels of the coiled tubing. The coiled tubing is formed of a combination of channels including strength component such as steel and having one channel that is at least lined with a non-metallic corrosion resistant surface where clean hydraulic fluid is carried from the hydraulic power system to the downhole hydraulic pump through the non-metallic corrosion resistant channel so to be less likely to pick up manufacturing and environmental particulates and corrosion by-products within the channel carrying the hydraulic fluid to the downhole hydraulic pump. The non-metallic corrosion resistant lined channel may comprise plastic pipe.

Abstract: Methods and systems are provided for inducing seismic vibrations into subterranean formations. Seismic transducers may comprise a frame, a reaction mass, a driver, and a baseplate. The driver actuates the reaction mass, imparting a vibratory energy to the baseplate. This vibratory energy is then imparted directly to the ground surface to propagate seismic waves into the formation. These seismic waves are then reflected by subsurface geological features. The reflected seismic waves may then be detected and interpreted by seismic detectors to reveal seismic information representative of the surveyed region. An external dampener may be secured to the baseplate, which provide, among other benefits, a damping effect to the baseplate. Advantages include, reduced undesirable baseplate harmonic distortion or “ringing,” reduced baseplate decoupling, and reduced seismic noise due to flexure reduction and more uniform baseplate-to-ground conformance.

Abstract: Methods and systems relate to recovering hydrocarbons from within formations in which hydrocarbon bearing reservoirs are separated from one another by a fluid flow obstructing natural stratum. Relative to the reservoirs, the stratum inhibits or blocks vertical fluid flow within the formation.

Fluid communication established by the drilled bores enables production utilizing a producer borehole deviated from vertical and processes that rely on techniques such as gravity drainage through the fluid flow paths and/or injection through the fluid flow paths.

The binary fluid density allows the separation device to distinguish the target recycle material from drilling solids and recycles the target material to the drilling operations for re-use in drilling fluid. The binary fluid is recovered and refreshed to maintain a generally continuous process of targeted recycling.
