Horizontal Well Applications
For the first time in the history of the Canadian oil industry, the year 2011 will witness more horizontal wells being drilled than vertical. This is the result of the rapid advancements in how we drill, complete, and frac Hz wells which made MFHW’s very profitable. Further, many of the challenging reservoirs/formations the industry is dealing with now, fall in the category of tight, super tight and even ultra tight in the term of the formation permeability. Unconventional reservoirs, such as shale gas, CBM and siltty sandstone, cannot be produced economically without the applications of MFHW technology.
PMG has taken the lead in helping many oil companies to make important decisions that can reduce development costs and improve project's NPV. The use of specialized software (Topaze and Rubis) and experienced staff, allowed PMG to offer the following services:
- Spacing between the horizontal wells
- The number of frac stages or the spacing between the fracs
- Open hole vs cased hole completion
- Taking advantage of sweet spots present along the Hz well
Mini Frac Applications
PMG recommends the use of Mini Frac for the following reasons:
- Obtain important data for frac design
- Obtain other reservoir parameters
- Optimize water/fluid injection in EOR schemes
- Avoid over-injection (over the frac pressure)
- Avoid under-injection (much lower than the frac pressure)
- Determine ceiling injection pressure for steam-flooding projects (ERCB requirement)
- Fracture Propagation Pressure
- Instantaneous Shut In Pressure (ISIP)
- Fracture Gradient (ISIP/depth)
- Fracture Closure pressure (FCP)
- Net Pressure
- Identify leakoff mechanism and Coefficient
- Flow regime
