.... Shale gas production in China has met a surge in the number of drilling wells. Those new wells were characterized by a relatively low gas production rate (<1×10 6 m 3 /d) in comparison with shale gas wells in the US. As a result, flaring gas during well completion needs to be recycled or used...

...Craig Cipolla; Jennifer Wolters; Michael McKimmy; Carlos Miranda; Stephanie Hari-Roy; Aicha Kechemir; Nupur Gupta Summary In 2019, the operator embarked on a very ambitious data acquisition project in the Bakken, with the goal of mapping far-field drainage and characterizing completion performance...

... back water autonomously after water breakthrough. To fulfill a suitable design of a long horizontal well with the RCP completion, a detailed understanding of multiphase-flow behavior from the reservoir pore to the wellbore and production tubing is needed. Coupling a dynamic multiphase-flow simulator...

..., closed completion with the cyclic injection of high‐pressure gas, which expands and rapidly displaces fluid at high velocity from deep in the well. Development of the system was a collaboration internally and in conjunction with the vendor to install what was historically a vertical‐well assembly through...

...Dmitry Ridner; Taylor Frick; Ding Zhu; Alfred Daniel Hill; Renzo Angeles; Narendra Vishnumolakala; Chris Shuchart Summary Acid jetting occurs as a result of pumping acid through limited‐entry liner completions, causing high‐velocity streams to impinge against the wellbore wall. The dissolution...

... and frac-pack completions. In unconventional resources, an improper choke-management strategy may trigger proppant crushing or the flowback of proppant, resulting in fracture closure and loss of production. In frac packs and high-rate water packs, an abrupt increase in the rate (or drawdown) may induce...

...R. D. Barree; J. L. Miskimins; K. J. Svatek Summary Horizontal-well developments, focused on transverse hydraulic-fracture stimulation, have evolved rapidly during the past decade. Many of these completions may have missed or bypassed significant reserves that were intended to be produced from...

... the upper completion. In the Augvald Graben, the upper part of the Zechstein group (the Turbot Bank formation) consists of marl overlain by an anhydrite unit. The anhydrite has a proven thickness of 18 m in Well 16/2-7, but it is absent on the Avaldsnes High. The lower part of the Zechstein group...

... was deployed successfully, accessing the laterals. The oil and gas industry is constantly advancing well technologies to increase recovery and reduce production costs, especially as more-complex reservoirs are being targeted. The idea of increasing reservoir contact with multilateral completions started...

Without a realistic prediction of the decline resulting from a given completion, it is impossible to assign value to one design over another and equally impossible to optimize the treatment for whichever goal is sought, either acceleration...

...V. J. Pandey; R. C. Burton; M.. Nozaki Summary Frac-pack techniques were used in a recent subsea well-completion campaign. The sandstone layers that were targeted for completion are present generally in shallow gas reservoirs, with depths ranging from 2,000- to 4,500-ft (609.60- to 1371.60-m) true...

...Vibhas J. Pandey; Aquiles J. Agreda Summary The Sacatosa field in west Texas was discovered in 1956. Since then, more than 1,500 wells have been drilled and completed in the main reservoir section known as the San Miguel 1. The San Miguel 1 is primarily low-permeability sandstone, with several...

Brown; Edmond Shtepani Summary This paper studies the effect of viscosity and fines-particle loading on the pressure drop across a 4-mm orifice in a specific geometry built to mimic a representative well completion. It also provides experimental...

Moreover, reservoir models are rarely predictive at the spatial and temporal scales required to identify control actions. We show that simple, closed-loop...

The authors of this paper will evaluate multiple completion strategies in two offset horizontal wells drilled in the oil section of the Eagle Ford shale. The first well...

A change in completion philosophy was proposed after detailed analysis of the test results. Well X-1 was retested...
