Consulting
CWC does a lot of consulting work. This includes, but is not limited to Drilling plan reviews, relief well planning, gas dispersion modeling etc.
Drilling Plan Review and Enhancement
The Drilling Plan Review and Enhancement is a tool that can be used when drilling critical wells, wells with suspect pressure regimes or wells with narrow pore pressure and frac gradient windows.
The drilling plan is reviewed so that calculations for the following parameters can be made.
Frac gradient
Surface pressures while circulating out a kick
Kick volumes during influx removal
Mud gas separator performance
Maximum surface pressure for evacuated wellbore
Bullhead kill
Gas Dispersion Modeling
The proximity of some drilling and production operations to the general public often presents an elevated level of risk exposure. In order to mitigate that risk, gas dispersion modeling has been used to determine the impact that a full scale blowout will have on the nearby surroundings.
CWC will use open flow potential data supplied by the operator as input into the Breeze HazPro® gas dispersion modeling program. This program can be used to calculate the gas concentration for a variety of meteorological and surface terrain scenarios in the area surrounding the well. This data can be useful during the early stages of a major well control event to determine the impact area and the necessary response. The dispersion data can also be used to develop a Blowout Ignition Plan to determine when a blowout should be ignited.
Blowout Ignition Criteria
The decision to ignite a blowout should not be taken lightly. Preplanning for igniting a well is important when such a serious decision is required. CWC can supply the operator with recommended ignition criteria for the gas storage wells. The criteria will be based on a number of factors to be determined during the data gathering phase of this project. The gas dispersion profile calculated for each well will also be used to develop an ignition plan for each well. Radiant heat calculations for the wells that are recommended to be ignited will be performed as a part of this exercise.
