... at the reservoir depths, and design a single-trip gravel pack and treatment system. A non-polymeric viscoelastic surfactant was selected for its proppant suspension capabilities and compatibility with a filter cake breaker. Due to the high reservoir pore pressure, a high-density brine (14.0 ppg CaBr 2 ) was chosen...

... whereas Thru-Tubing Gravel Pack (TTGP) is retrofit sand control method, which the sand control principle is similar to conventional Cased-Hole Gravel Pack (CHGP), but can be installed in a smaller completion size. In Zawtika existing development phases, almost 150 zones of sand producing intervals...

... Abstract Multi Zone Single Trip Gravel Pack (MZ-STGP) system has been the solution for developing sand prone reservoirs in the Mahakam Delta, Indonesia. Despite providing cost effective solutions, few sand control failures has been recorded. It is deemed necessary to understand the cause...

... Abstract Thru-Tubing Gravel Pack Techniques have been receiving an increasing attention in the recent years as a cost effective solution for sand producing wells with either failed gravel packs or zones that started sand production at a later stage during the life of the well especially...

.... It will also describe a number of enabling technologies pioneered by ExxonMobil including: • NAFPacSM, a gravel pack technique that allows the operator to run the gravel pack screens in non-aqueous fluid, gravel pack the well and displace the casing to brine, all in one trip • MazeFlo™, a self healing...

... at the sand face. This new technology can be installed over traditional sand screens in gravel pack or frac pack applications, with no negative impact on the sand control functionality of the screens, or the quality of the pack. The installed fiber optic provides the equivalent of a strain gauge positioned...

... stage, workover with conventional gravel packing is one way to alleviate the problem, but such a costly undertaking is not always economically justifiable. The candidate field is located at offshore Terengganu in Malaysia and has been in production since 1982. The reservoir consists of several layers...

... Abstract Cased-hole gravel packing is commonly utilized to control sand production from oil and gas wells. The success of a cased-hole gravel-pack job depends on the ability to effectively pack perforation tunnels, which act as conduits between the reservoir and the wellbore for hydrocarbon...

... to mitigate solids production. A Horizontal Open Hole Gravel Packed (HZOHGP) was chosen as the optimal solution for particle size range, cost and long term integrity. Five horizontal wells were drilled and successfully completed with a 1,000 ft open hole section and 7-inch production tubing. The gravels were...

... in Serbia is gravel pack, and almost third of total oil production comes from wells with gravel pack. Sand control management, monitoring and well maintenance are essential to achieve planned oil production and to decrease operational costs. Presence of clays in sandy collectors leads to poor gravel pack...

... precautions the wells tend to sand-up, ceasing all flow from the reservoirs. The sand control techniques used for the field include openhole gravel packs, expandable sand screens, and cased hole gravel packs. The wells in question have two different types of completion. The first one is an openhole completion...

... recovery. Major investments like well head - or front end compression could be delayed and thereby appreciable cost savings are generated. After initial well test results it was concluded that all wells in the Miano gas field will need gravel pack installations in order to protect completion and surface...
