Hydrajet fracturing, which can place multiple propped hydraulic fractures in precise locations, effectively stimulated two underperforming horizontal openhole gas wells in the low-permeability Cardium ...

Efficient drilling in shale reservoirs requires detailed 3-dimensional (3D) horizontal well trajectories. An orthogonal-arc trajectory (OAT) method assumes a single constant curvature in the curved ...

The change could represent a breakthrough at Chicontepec, a field that holds about one-third of Pemex’s proven reserves but where tricky tight carbonate reservoirs have confounded efforts to boost ...
