CBHP is an MPD technique that controls or reduces the effect of circulating frictional losses thereby maintaining the bottom hole pressure within pore pressure and fracture pressure
It consists of multiple horizontal wells and simultaneously injecting high volumes of steam above the rock fracture pressure
Previous research on formation stability shows that the empirical value of the formation fracture pressure
The pore pressure, collapse pressure and fracture pressure of formation compose the safe density window of drilling fluid under the static condition.
f] is the safety value-added for the formation fracture pressure, g/[cm.
Formation pressure matrix includes pore pressure matrix, collapse pressure matrix and fracture pressure matrix.
On the basis of the formation pore pressure matrix, with the conventional formation fracture and collapse pressure calculation methods, the fracture pressure matrix and the collapse pressure matrix would be built by the similar simulation method.
The release also includes a new module for log-based pore pressure and fracture pressure
prediction that optimizes drilling safety and helps optimize the economics of the drilling program.
Under the terms of the agreement with Knowledge Systems, A2D will supply its vast well log data for the creation of pore pressure and fracture pressure
key attributes about the geological storage such as porosity, injectivity, fracture pressures
and storage risks.
Today many of the programs have been consolidated and there are 18 programs in the Maurer software suite that help clients design wellbore trajectories, design and verify casing strings, minimize casing wear, design cement jobs, analyze torque and drag, verify wellbore hydraulics, plan for well control, determine pore and fracture pressures
, determine wellbore stability and numerous programs for coiled tubing design and completion programs.
