作业者冒险进入深水区域将面临大量的技术挑战。钻井泥浆的设计必须强调传统的工程问题，如井底清洁、井壁稳定、岩屑稳定和可能的天然气水合物地层。在墨西哥较深的井段，孔隙压力和压裂梯度之间的压差或许是非常小。在陆地，压裂压力是由地层施加的上覆岩层压力的函数值。另一方面在海洋的应用，海水减少了上覆岩层压力梯度。在深水钻井中，为了使钻井泥浆能从井底泵送到海平面以上接近80－100ft的钻台上。在合适的套管鞋位置被确定之前，大量的井必须在直至海底都无隔水管的情况下被钻进。当作业者进入深水区域时，钻井泥浆必须被设计成适合于低压裂梯度和潜在的天然气水合物地层的泥浆。
Operators risk entering the deep water will face a large number of technical challenges. Drilling mud designs must emphasize traditional engineering issues such as bottomhole cleaning, borehole stability, cuttings stabilization and possible gas hydrate formations. At deeper intervals in Mexico, the pressure difference between pore pressure and fracturing gradient may be very small. On land, fracturing pressure is a function of overburden pressure exerted by the formation. On the other hand, in marine applications, seawater reduces the overburden pressure gradient. In deep-water drilling, drilling mud is pumped from the bottom of the well to a rig that is close to 80-100 ft above sea level. Before a suitable casing shoe position can be determined, a large number of wells must be drilled without risers until the sea floor. When the operator enters a deep water zone, the drilling mud must be designed to be mud suitable for low fracturing gradients and potential gas hydrate strata.
