Abstract: A method of fracturing a reservoir wherein the main fracture stimulation treatment is preceded by depositing non dissolving solids into fracture tips where excessive downward or upward fracture growth is not desired, thereby controlling fracture geometry. The method thereby increases production of a fluid, such as water, oil or gas, from said reservoir, and avoids fracture propagation out of the pay-zone into undesirable zones.

Abstract: Hydraulic fracturing of subterranean formations has become more complex and detailed as information increases. Methods for calculating and monitoring reservoir pressures during treatment provide unique opportunities to adjust treatments on the fly. Treatments include acid fracturing, fracture acidizing, acid stimulation, propped acid fracture stimulation, hydraulic fracturing, slick water based hydraulic fracturing, foamed based hydraulic fracturing, foam based acid fracturing, foamed based acid diversion, any other physical particulate and fiber based hydraulic fracturing or matrix treatment.

Abstract: Reducing leak-off during acid stimulation with dissolvable material sized to preferentially block crevices and wormholes, thus allowing the acid to travel further down the fractures, etching deeper into the reservoir than a similar process not using such dissolvable materials. After stimulation, the materials dissolve and production can proceed and will be improved over what is possible without such dissolvable materials.

Abstract: Methods and systems are described for stimulating a subterranean hydrocarbon-bearing reservoir, one method comprising contacting the formation with a treating fluid, and monitoring the movement of the treating fluid in the reservoir by providing one or more sensors for measurement of temperature and/or pressure which is disposed on a support adapted to maintain a given spacing between the sensors and the fluid exit. In some embodiments the support is coiled tubing.

Abstract: A computerized handbook known as an ‘i-Handbook’ is adapted to be stored in a memory of a computer system and displayed on a display screen of the computer system for assisting field personnel in the performance of their respective job related responsibilities. The ‘i-Handbook’, when displayed, has the appearance of a real handbook and it includes a database and a plurality of calculators for calculating a plurality of oilfield or wellbore related data in response to a first plurality of data in the database and a second plurality of data input by a user. The plurality of calculators are adapted for calculating: unit conversions, triplex pump volumes, tank volumes, tubular stretch and free point, annulus volumes, slurry density, gate percentage, screen out, cement slurry, casing lift, HCL density, oil gravity and API, and salt requirements.

Abstract: The present invention relates to a method of determining the proppant friction generated in a fracture of a subterranean formation during a hydraulic fracturing treatment involving injection stages of pad and of proppant-laden fluids. This method is based on close monitoring of surface pressure to define a “net pressure rate” which defines an increase or decrease of net pressure while the job is being pumped, and then relates it with the pressure changes observed with the onset of proppant stages of varying concentrations.

Abstract: The invention is an interactive computer system for help in selecting well-services treatment fluid comprising a set of fluid families, a set of relevant fluid characteristics and a set of digital ratings of each fluid family with regard to these characteristics. The system further includes a set of job parameters pertaining to the treatment and qualitative ratings of said parameters estimating their relevance in the effective success of a treatment. An interface allows the user to enter the job parameters values known to him. Built in rules, associated with calculating means including an integrated spreadsheet, match fluid characteristics and job parameters and trigger the elimination of fluids that are not compatible with some value of the job parameters and compute a confidence index for the non-eliminated fluid families, said confidence index based on the one the sum of the products of the fluid families digital ratings and on the rating of the known job parameter.
