Using High-Angle LWD Data in Carbonates

LWD solutions are a cost-effective means of evaluating carbonate reservoirs Carbonate reservoirs often show a high degree of geological and petrophysical heterogeneity. The variations stem from differences in localized depositional environment and diagenesis, ultimately dictating the poro-perm, wettability and overall hydrodynamic behavior of the reservoir at field scale. Secondary porosity and fractures are often the objective target when designing well plans, since their...

Mature Field Rejuvenation with Infill Drilling

In this tough economic climate, efficient mature field rejuvenation has become a major challenge for operators looking to balance the books. The most successful mature field rejuvenation projects are ultimately driven by a solid understanding of the existing infrastructure, reservoir geometry, and remaining hydrocarbons in place. Most large mature fields were initially developed long before many of the technologies we use today were available, such...
