| 101 | METHOD FOR INJECTING LOW SALINITY WATER | PCT/EP2012059226 | 2012-05-17 | WO2012156495A2 | 2012-11-22 | BRODIE JAMES ANDREW; JERAULD GARY RUSSELL |
| Methods, apparatuses and computer readable instructions for determining the effectiveness of, and for performing, a low salinity waterflood. An ion diffusion distance value is determined based on the rate of diffusion of ions within the rock of a reservoir and the residency time of floodwater within the reservoir. The thickness of the layers of the reservoir are compared to this ion diffusion value to determine the effectiveness of performing a low salinity waterflood and also to enable the effective control of a waterflood and to assist in the determination of locations of wells. | ||||||

| A method of forming a wellbore with a drill string and that includes continuously and automatically measuring a TARE value of the drill string. The TARE value of the drill string is measured while the drill string is rotating, fluid is circulating in the drill string, and after the drill string has been axially stationary for a set period of time. The TARE value is designated as an average of the measured hook load over the latter half of the set period of time. Knowing the measured TARE value and a designated weight on bit (“WOB”) of the drill string, a hook load for supporting the drill string is calculated. Matching the force applied that supports the drill string to the calculated hook load results in an actual WOB that matches the designated WOB. | ||||||
