Current logistics and pipeline-infrastructure limitations make transportation and production of waxy crude oil challenging, necessitating a step change in the chemistry required to mitigate crude-oil-composition issues.

Banyu Urip crude contains 26% wax, which can lead to flow-assurance challenges in a crude pipeline exposed to lower temperatures. Injection of pour-point-depressant (PPD) chemicals has been considered an effective method to ensure flow of moderate waxy crude.

This paper presents a case study that is an example of how reassessing a flow-assurance risk-management strategy for operating assets can identify opportunities for optimization.

The last 3 years have seen an unprecedented increase in paraffin-related challenges. The featured papers give some insights into the work under way at some companies to elucidate the structure performance relationships between inhibitors and crude oils containing these higher paraffinic species.

Production from older wells in the Permian Basin is declining faster than widely assumed, according to a new study. If this trend holds, it could lead to problems for companies that are depending on those wells to pay for future development or to justify a big acquisition.

A real-time drilling-data analysis and recommendation system that leverages surface drilling data was deployed in a lateral section of a well from an artificial island in Abu Dhabi.

This work presents a systematic geosteering work flow that automatically integrates a priori information and real-time measurements to update geomodels with uncertainties and uses the latest model predictions in a decision-support system (DSS).

Natural gas, coupled with carbon capture and storage (CCS), could provide cheap and reliable energy in the long term and mitigate climate change. Gas-to-wire (GTW) generates electricity from natural gas at or near the field. This study applies an integrated GTW/CCS scheme to a gas-production field.

The pressure pumping giant turns to algorithms to get better fractures and fewer problems.

A demonstration project of carbon capture, utilization, and storage through enhanced oil recovery was conducted in Saudi Arabia. Surface facilities for such projects are expensive to build and involve tradeoffs in options based on economics for a given set of conditions.
