A well, penetrating a subterranean fluid-producing formation, is effectively gravel packed by a method comprising two sequential steps. In the first step, a slurry of gravel and carrier fluid is introduced into the formation at a pressure substantially in excess of the formation fracture pressure. In the second step, a slurry of gravel and carrier fluid is introduced into the

26/06/2000· Cement is often the preferred solution because of its well-established properties and proven performance. An increasing problem has been water production in gravel-packed wells. Chemical shutoff in a proppant pack cannot easily be achieved with standard cement slurries or specialized squeeze slurries because of the risk of bridging and incomplete

Well-plugging Equipment and Tools. 1. 10-gallon pail – used to mix Portland cement and water to make neat cement grout. 2. 2-foot by 3-foot ¼-inch screen – when formed into a cone, it is used to pass chipped bentonite through before it is poured into the well to separate out fines. 3. 8-foot and 16-foot 2-inch by 4-inch wood studs – used to tamp native clay as it is shoveled into the well

A water-producing zone in a reservoir penetrated by a gravel-packed well is isolated by placing a bridge plug in the well tubing adjacent to the top of the water-producing zone, then placing a first coarse sand on the bridge plug, followed by a fine sand on top of the coarse sand, and finally by placing a flowable resin on top of the fine sand where it spreads out through the gravel

well drilling Stockpiled over several years and waiting for an economically and environmentally acceptable solution, the gravel from Petrobras oil drilling operations began to be co-processed in 2007 in a cement plant in Brazil. Between 2007 and 2011, the cement plant was able to replace around 57% of its total natural clay supplies with waste gravel. This means that 150,000

The entire well completion process includes everything from casing the wellbore to cementing, plug and perf operations, gravel packing, and installation of a Production tree (or ‘Christmas Tree’) at the wellhead. Broadly speaking, there are two main well completion methods typically utilized: open hole and cased hole. Each of these methods,

15/01/2018· The success of a well depends on this primary operation. In addition to isolating oil-, gas-, and water-producing zones, cement also aids in Protecting the casing from corrosion; Preventing blowouts by quickly forming a seal; Protecting the casing from shock loads in deeper drilling ; Sealing off zones of lost circulation or thief zones; Remedial cementing.
