... for longer period of time compared to any current products available, but also causes no significant damage to the proppant-pack conductivity. Additionally, it is environmentally-safe and cost-effective. This paper will describe the laboratory testing involved in developing this new technology in detail...

... releases the adsorbed scale inhibitor into the bulk water as it flows through the propped zone, providing immediate and long-term protection against solids deposition. Solids deposition can restrict production pathways through the proppant pack, contributing to loss of conductivity. Results...

... is proposed and a summary of the results are presented. This new approach enables us to not only determine the behavior of different proppant pack over a wide range of pressures but also to determine failure point of proppant at a given concentration. The new proppant crush test approach was used to compare...

... or conventional tubing coupled with a pressure-pulsing tool. The treatment fluids are designed to provide consolidation for previously placed proppant near the wellbore without damaging the permeability of the proppant pack. The consolidation treatment transforms the loosely packed proppant in the fractures...

... treatments are applied and present a methodology for evaluating a damaged well. A treatment was specifically designed to remove the proppant pack damage and create an effective stimulation for the character of the reservoir rock. The pressure response from the third treatment will demonstrate removal...

... separated from the slurry and held in the slot. This "grain sorting" mechanism continued until all available grain sites along the slot entry were occupied. Once the slot was bridged additional proppant was deposited upstream from the bridge, forming a dehydrated proppant pack. Differential pressure across...

... Abstract Fluid viscosity reduction is an important gauge of polymer degradation, and, although viscosity reduction does indicate that polymer degradation has occurred, reduced viscosity does not necessarily indicate that the proppant pack and the formation are undamaged. Polymer fragments which...

... of potential or actual production. For sustained, high production levels, the proppant pack's integrity must be maintained. With time, most proppant packs are damaged by fines migration, gel clogging, and geochemical precipitation. These processes can be abated with various additives and techniques. This paper...

... Abstract Significant gel break problems may exist when using borate crosslinked fluids with resin coated proppants (RCP). A test method was developed which measures proppant settling, fluid breakdown, and flow of broken fluid through the settled proppant pack. Generally, sand settling...
