A unitary pipe loop component for use with a sinker bar and a pair of pipes in a wellbore includes a return bend pipe fitting having a fluid flow passage configured to extend between the pipes in the wellbore, and further includes a sleeve having a passage with open opposite ends to receive the sinker bar through the sleeve. A weight suspension structure is connected to the sleeve and the pipe fitting as another distinct portion of the unitary pipe loop component, and has a knockout portion configured to provide an eyelet for insertion of a hook, tether, or the like for suspension of a weight. The eyelet may alternatively receive an anchor.

A system and method for on-line training of a support vector machine (SVM). The SVM is trained with training sets from a stream of process data. The system detects availability of new training data, and constructs a training set from the corresponding input data. Over time, many training sets are presented to the SVM. When multiple presentations are needed to effectively train the SVM, a buffer of training sets is filled and updated as new training data becomes available. Once the buffer is full, a new training set bumps the oldest training set from the buffer. The training sets are presented one or more times each time a new training set is constructed. An historical database of time-stamped data may be used to construct training sets for the SVM. The SVM may be trained retrospectively by searching the historical database and constructing training sets based on the time-stamped data.

A sealed well direct expansion geothermal heat exchange unit, whose sealed well can be placed in ground and/or in water, consisting of a conventional direct expansion, or other heat pump, system wherein the exterior refrigerant heat exchange lines are placed within an insulated and sealed container, which container is supplied with a circulating heat conductive liquid from and to a sub-surface sealed well encasement, which container liquid may be supplemented with heat from a solar heating system, and which unit's hot refrigerant vapor line may be supplementary cooled by means of condensate water evaporative cooling.

Disclosed is a system and method for directing data representing well operations (drilling and producing) through the Internet or similar wide area network. The instant invention comprises a system and method of installing sensors at the well to provide technical information to remotely-located Internet users who provide services to the well owner. The service providers may be observers, who may then advise the well owners and operators as to actions to take to increase or optimize well performance. Service providers may also be data storage companies, who clean and store the data from the well. Service providers may then be paid from a portion of the well revenues or a portion of the incrementally-increased revenues.

A system for installing sub-surface fluid transport tubing and pressure testing coupling seals in a vertically oriented geothermal heating/cooling system installation, and particularly in a direct exchange system installation, includes providing an elevated containment area, that has a confined space opening, supported by extensions/poles, within which opening an upper portion of the fluid transport tubing segment, to be installed within the borehole, can be positioned and contained. The system further includes pressure testing above-ground segmental coupling seals, by using moderate gas pressure applied via temporary gas hose and plug connections to respective ends of the operatively connected fluid transport line set.
