Completions
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

This paper aims to develop criteria for identifying situations in which induced fracture complexity and sustained conductivity are or are not required. -
This study provides a model for the inclined fracture case. It applies and further extends the unified-fracture-design approach for rectangular drainage areas, relating the dimensionless proppant number to the maximum productivity index in pseudosteady-state conditions.
-
The lower tertiary formation found in the pre-salt layers of the Gulf of Mexico has become a proving ground for extending what is possible when completing multistage fracturing in ultradeepwater wells.

A deepwater field located offshore Sabah, east Malaysia, features a spar dry-tree unit (DTU) and multiple subsea-hub tiebacks to a floating production, storage, and offloading vessel (FPSO).
-
Southwestern Energy plans to be freshwater neutral in its hydraulic fracturing operations by next year, and the company is well on its way to achieving that goal, said the leader of the group responsible for bringing it to fruition.

You have probably heard that the Eskimo language has several dozen words for “snow,” a frequently repeated and well-known idea. It is untrue. A meme is a snippet of culture that is learned by imitation and passed on by imitation or repetition.

An ongoing research project started nearly 3 years ago by the US Department of Energy’s National Energy Technology Laboratory (NETL) is shedding new light on what really happens to foamed cement as it is pumped deep down offshore wells during completions.
-
This paper describes thermal modeling and its combination with drilling-fluid analysis to reveal concealed changes in well conditions during various drilling and completion operations.

A large mature onshore Saudi Arabian oil field is producing sour crude oil that multiplies well-integrity challenges.
-
The authors describe the development of well-control techniques that allowed successful drilling operations in the Piloncillo Ranch lease in south Texas.
