Rover Pipeline Project- Over the course of 7 months in 2017-18, DCS participated in the successful drilling for 24 individual bores totaling more than 43,000 feet of 42" pipeline installation. We provided drilling fluid additives conforming to the strict standards required by the project owner and state and federal regulatory agencies. DCS drilling fluid engineers were instrumental in supervising fluid additive usage and mixing, analyzing ground conditions for additive decisions and providing borehole pressure data planning.
Hardrock Intercept / Kemah, TX.- One of the longest horizontal bores at the time, Hardrock Directional Drilling counted on DCS to provide the fluid additives and the engineering to complete an 11,328 foot long bore. As with many of the bores we are involved with, DCS provided accurate predictive Annular Pressure calculations to prevent inadvertent returns to surface, which proved very effective in preventing frac-outs and lost returns. Our on-site engineering services kept the drilling fluid in peak condition, in this case utilizing DCS HDD Lube to improve the reaming process and control pull pressures.
New Orleans Levy – DCS Fluid Solutions worked with a number of HDD contractors on more than 30 critical levy bores under the auspices of the Army Corps of Engineers in Louisiana. All of these bores required close coordination with the Army Corps, drilling contractors and engineering firms to insure zero damage was done to the levies during the boring and construction process as these levies protect millions of folks from flood waters. One notable bore was completed in the New Orleans region. At over 8200’ in length this project was drilled under 2 levies. The drilling was performed by Harding Directional at or below the predicted annular pressures worked up by DCS to prevent any damage from inadvertent returns to the surface of the levies.
