Drilling
Oil and gas companies drilled 75 “high-impact” wells in 2024, representing 5.2 billion BOE.
This paper presents a comprehensive literature review of perforate, wash, and cement techniques that compares new methods with traditional ones and uses field cases and computational fluid dynamics to find the most cost- and time-effective practices without sacrificing safety.
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.

Vimlesh Bavadiya is leading a team of engineering students at the University of Oklahoma (OU) to repeat its victory in SPE’s Drillbotics competition next year. -
With the innovation of extended-reach and directional drilling, running casing and liner strings has become increasingly difficult.

While rotary-steerable systems (RSSs) dominate the offshore directional-drilling markets, the land-based markets are still dominated by conventional directional-drilling tools. This paper presents a new RSS that is being designed and tested specifically for the onshore markets.
-
The understanding and proper application of rotary-steerable systems will continue to provide a step change in the way fields are developed. Technology developed and implemented during the boom will receive closer scrutiny and evaluation during the bust.

Drilling the Severnaya Truba field in Aktobe, Kazakhstan, has been costly and time consuming.

The strength and conductivity of proppant packs are key parameters for assessing their performance. This paper introduces a new analysis technique based on interpretation of acoustic measurements to quantify mechanical damage in propping agents.

This paper offers insight into an integrated effort at combining analytical information, numerical well-test models, and geological evidence to explain the reservoir behavior observed in the Huntington field.
-
For thin-oil-rim reservoirs, well placement, well type, well path, and the completion methods must be evaluated with close integration of key reservoir and production-engineering considerations.
