Formation Pressure Evaluation While Drilling - Fracture Gradient, Leak-Off Tests and Kick Interpretation
Formation pressure evaluation finds where pore fluids are above the normal hydrostatic gradient and estimates that pressure well enough to […]
Subsea Manifolds and Templates - Cluster vs Daisy-Chain Architecture, Pigging Design, and Wellhead Interface Engineering
Subsea manifolds and templates gather the production of several wells on the seabed and send it to a host facility […]
Total Well Costs: From Initial Planning to Abandonment
Total well cost is the financial result of the engineering decisions made in the well design: the rig and its […]

A well cost estimate, presented to partners and management as an authorisation for expenditure (AFE), is built from the well […]
Geostatistical Reservoir Modeling: Variograms, Kriging and Simulation
Geostatistics fills a reservoir grid with properties (facies, porosity, permeability, saturation) between the few locations where wells sample the rock. […]
Detailed Time Estimate: The Key to Precise Well Planning
A detailed time estimate links each activity to its quantity, its duration basis and its predecessors, and adds up to […]
Delayed Coking: Drum Operation, Coke Morphology, Resid Conversion Chemistry, and Delayed Coker Economics
Delayed coking converts vacuum residue, the heaviest and most contaminated part of the crude barrel, into gas, naphtha, light and […]
Scale Management in Production Operations: Formation Mechanisms, Saturation Indices, Inhibitor Squeeze Design, and Removal Strategies
