formation evaluation

The authors of this paper describe the characterization of fractures in the Mesozoic sandstones of the Phra Wihan Formation exposed at the southern part of Uttaradit Province in Thailand.

This paper proposes a multidomain approach to tackle petrophysical and geomechanical aspects of a fracture system governing the carbonate layer of an exploration well in Kuwait to assess producibility and qualification for stimulation.

Geochemical parameters such as total organic carbon (TOC) provides valuable information to understand rock organic richness and maturity and, therefore, optimize hydrocarbon exploration. This article presents a novel work flow to predict continuous high-resolution TOC profiles using machine learning.

There is a thin line between success and failure of clay stabilizers as they can either drive performance or cause unwanted formation damage.

The authors introduce and compare two quality-control approaches based on two different signal-processing practices.

This paper describes the acquisition and interpretation of long-term pressure-buildup data in a plugged and abandoned deepwater appraisal well.

Diagnostic fracture injection tests (DFITs) incur direct and indirect costs resulting from the tests themselves and the extended time required for the pressure falloff, which delays the completion of the well. The benefits, therefore, must outweigh the costs if the test is to be justified.

This paper bridges the gap between operational petrophysicists and FTS specialists, introducing an automated work flow by which petrophysicists can conduct FTS jobs.

A new multilayer boundary‑detection service has been introduced to resolve the geological uncertainty associated with horizontal wells in Bohai Bay. Geosteering and real time reservoir characterization were used to reduce the uncertainty.
