Problems solved by technology

In addition, after taking measurements and completing the logging process, the operator cannot interrupt immediately after restarting the pumping unit at the point of the fracturing process
Instead, the operator must repeat the complete fracturing job, introducing additional costs and unpredictable results

Embodiment

[0128] Pre-cured resin was prepared by pre-mixing 70 grams of Oil Well Resin OWR-262E (which is a liquid phenolic resole resin) and (3.75 grams of 80%) or (6.0 grams of 50%) of a solution of vanadium alloy complex coating. The premixed solution was then added to 1 kg of the fracturing substrate preheated to a temperature of 380-400°F (193-204°C). The substrate and premix solution are then mixed together under constant agitation. Surfactant (Chembetaine) was added to the cycle at 2 minutes 30 seconds. Agitation was stopped at 3 minutes and 40 seconds and the coated material was placed in an oven preheated to 320°F (160°C) for a post bake of 3 minutes and 40 seconds. The coated material was then removed from the furnace and cooled to room temperature.

[0129] Using the above procedure, several vanadium alloy composites (with different particle sizes) were prepared for further testing. The results are shown in Table 1.

Abstract

Articles and methods utilizing radiation susceptible materials are provided herein. In one aspect, a proppant, a treatment fluid, or both, may comprise a radiation susceptible material. In another aspect, a method is provided comprising disposing in a formation fracture, a proppant and / or a treatment fluid that comprises a radiation susceptible material, irradiating the radiation susceptible material with neutrons, measuring gamma-radiation emitted from the radiation susceptible material in a single pass, and determining formation fracture height from the measured gamma-radiation. The single-pass may be a continuous process or a periodic process.

Description

[0001] relevant application data [0002] This application is a continuation-in-part of the concurrently pending application of U.S. Patent Application No. 12 / 789094 filed on May 27, 2010, which is U.S. Patent Application No. 11 / 501575 filed on August 9, 2006, authorized A divisional application of Application No. 7726397, which claims the benefit of US Provisional Application No. 60 / 706791, filed August 09, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to methods and compositions for determining the geometry of fractures in subterranean formations. Background technique [0004] The production of hydrocarbons, such as gas and oil, from subterranean formations can be increased by fracturing the formation to stimulate the flow of these hydrocarbons in the formation. A variety of formation fracturing methods are currently used, such as hydraulic fracturing, in which liquids, gases, or a combinat...
