... and setting of the TTIRP within the production liner close to the uncased reservoir section. Following successful anchoring of the TTIRP, the CT was disconnected from the packer assembly and a sand plug was utilized to protect the fishing neck. The CT was then retrieved to the surface, and a slickline dump...

Challenges include correct tools, equipment, job design, procedures, weather, limited deck space, personnel movement control and ensuring each well...

... Abstract In the gas and oil industry, efficiency optimization within unconventional reservoirs persists as a crucial and formidable challenge. As the exploration and development of these reservoirs advance, horizontal wells are being drilled to increasingly greater depths. Plug and perf (P...

... section, ensuring the cleanliness of wellbore for fluid replacement; During reservoir transformation and production, the soluble sieve tube is dissolved in acid and the soluble pore plug is used to reduce fluid flow resistance. The release short section can be repaired and salvaged in sections by shearing...

... of the best core plugs for testing. Unconfined compressive strength (UCS) tests were performed at atmospheric confining stress (confining pressure is zero) and "as received" condition at room (20-25 ° C) and elevated (200 ° C) temperatures to simulate the operation conditions during steam injection. Thin...

... multi-stage triaxial procedure. Eight (8) plugs representing the Baong and Belumai Formations of the North Sumatra Basin and eight (8) plugs representing the Talangakar and Gumai Formations of the South Sumatra Basin were prepared in vertical (V), horizontal (H), and 45° inclined (I) orientation...

.... With the operator's decision to drill a sidetrack from the original well, an engineered cement slurry was designed to cure losses, plug and abandon the original hole, and act as a kick-off point for another trajectory. The cement job was intended to be pumped and displaced through the drilling assembly and through...

... temperatures. Three different acids were used which were hydrochloric (HCl), formic (HCOOH) and acetic (CH3COOH) acids. These acids were injected at a fixed rate of 2 cm 3 /min into Indiana Limestone core plugs at two different temperatures: 150 and 250°F using coreflood equipment. Non-destructive...

... Abstract This methodology presents an efficient implementation of solid degradable particles to address zone isolation failures in plug and perforation (Plug and Perf) acid fracturing operations, thereby facilitating proper zone stimulation without the need for subsequent well interventions...

..., bridging, plugging, diversion and degradation, which are the tools required to provide reservoir and completion specific design guidelines for various scenarios. Each model is built using dedicated experimental procedures. Experimental data are presented together with their correlations. The efficiency...

... Abstract Characterizing oilfields involves testing rock plugs. However, carbonate reservoirs like the Brazilian pre-salt basins pose challenges due to their high heterogeneity and deepwater location, making plug extraction costly and risky. To address and contribute to this issue, a new...

... are drilling lateral lengths between 9,000 and 15,000 ft. This analysis will focus on optimizing frac plug drillouts (also known as mill out) and cleanouts of frac plugs in extended reach laterals under high pressure and high-temperature conditions using Hydraulic Completion Units (HCU). In the preplanning...

In addition, coreflooding experiments were performed to quantify the impact of oil content, dissolved and suspended solids, and particle sizes on the injectivity loss as a function of time core plugs. Treatments to remove or bypass...

... Abstract The use of Y-tool assemblies permits production logging and stimulation work in Electric Submersible Pump (ESP) oil well completions. Auto Y-tools use a valve design which preclude the need for a blanking plug used in conventional Y-tool completions and hence provides an alternative...
