Reservoir
This study demonstrates how routinely acquired downhole temperature data allows for direct estimation of fluid saturations and delivers more accurate reservoir volume assessments, particularly in aquifer-supported systems.

Effective data analysis depends on seeing connections that matter. Explore how Spotfire enables a more intuitive approach to understanding petroleum data.
The deal adds over 1,000 potential drilling locations and almost doubles oil production for Houston-based Magnolia.

Drilling, completing, and fracturing of unconventional-formation wells in North America have become commonplace for producing natural gas. It is less common to drill, complete, and fracture treat multiple lateral branches from a single main wellbore. -
A test-case study (Norne E-segment), based on field data of an offshore Norway brownfield, was organized to evaluate and compare mathematical methods for history matching and strategies for optimal production or enhanced oil recovery (EOR).

A nonlinear orthogonal-matching pursuit (NOMP) for sparse calibration of reservoir models has been proposed. Sparse calibration is a challenging problem because the unknowns are the nonzero components of the solution and their associated weights.

Reservoir simulation is essential in the decision-making process for the development and management of petroleum reservoirs. A simulation model can predict the reservoir behavior under various operating conditions.

Changing the salinity of injection water could make the difference in getting more out of existing wells.

Using low-sal water for flood can add 30% to the amount of oil that can be recovered from a reservoir. What is the theory behind it?

A recent webinar discussed current technologies to enable reuse of produced water in gas and oil shale developments.

ExxonMobil is testing its Controlled Freeze Zone technology, a single-step cryogenic process that allows carbon dioxide (CO2) to freeze in a controlled method and then melts the CO2. After recovery of the methane, the CO2 can be sequestered or used for EOR.

Industry proponents and many leading academic institutions agree that natural gas is the safest, cleanest-burning bridge fuel. One risk in the development of this resource involves the inevitable leakage of methane.

Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.
